Breaks linear

Description

Generate a breaks vector of size n with linearly spaced breaks.

Usage

breaks_linear(n = 10)

Arguments

n

<int> the size of the output vector. Ouput size will be at least length-2 for finite input.

Details

If input range is non-finite, an empty vector is returned.

See Also

Other breaks: breaks_log(), breaks_manual(), breaks_power(), breaks_symlog(), breaks_trans()

Examples

breaks_linear(5)(-10:10)
breaks_linear()(-1:1)

Breaks log

Description

Generate a breaks vector of size n with log log_trans spaced breaks.

Usage

breaks_log(n = 10, base = exp(1))

Arguments

n

<int> the size of the output vector. Ouput size will be at least length-2 for finite input.
base

<number> The log base

Details

Input range must be finite and either be strictly negative or strictly positive; it must not cross, nor include 0.

If input range is non-finite, an empty vector is returned.

Note

This function has a different goal to scales::breaks_log: it produces evenly spaced log-breaks for use with d3-scale, it doesn't produce breaks with pretty labels.

See Also

Other breaks: breaks_linear(), breaks_manual(), breaks_power(), breaks_symlog(), breaks_trans()

Examples

breaks_log(5)(-10:-1)
breaks_log(5)(1:10)

Breaks manual

Description

Generate a breaks vector with pre-determined threshold values.

Usage

breaks_manual(thresholds = 0.5)

Arguments

thresholds

<numeric> a numeric vector of ordered, finite thresholds.

Details

Wraps thresholds in the range of input data (which may be null or non-finite). Thresholds that fall outside the range of input are omitted from the output.

See Also

Other breaks: breaks_linear(), breaks_log(), breaks_power(), breaks_symlog(), breaks_trans()

Examples

breaks_manual(0)(-10:10)
breaks_manual(c(-10, 0, 10))(-10:10)
breaks_manual(-1:1 * 1e6)(NULL)

Breaks power

Description

Generate a breaks vector of size n with exponentially power_trans spaced breaks.

Usage

breaks_power(n = 10, exponent = 0.5)

Arguments

n

<int> the size of the output vector. Ouput size will be at least length-2 for finite input.
exponent

<number> The power exponent

Details

If input range is non-finite, an empty vector is returned.

See Also

Other breaks: breaks_linear(), breaks_log(), breaks_manual(), breaks_symlog(), breaks_trans()

Examples

breaks_power(5)(-10:10)
breaks_power(5, exponent = 1 / 3)(-1:1)

Breaks symlog

Description

Generate a breaks vector of size n with log1p symlog_trans spaced breaks.

Usage

breaks_symlog(n = 10)

Arguments

n

<int> the size of the output vector. Ouput size will be at least length-2 for finite input.

Details

If input range is non-finite, an empty vector is returned.

See Also

Other breaks: breaks_linear(), breaks_log(), breaks_manual(), breaks_power(), breaks_trans()

Examples

breaks_symlog(5)(-10:10)
breaks_symlog(5)(0:10)

Breaks trans

Description

Generate a breaks vector of size n with evenly spaced breaks in trans domain.

Usage

breaks_trans(n = 10, trans)

Arguments

n

<int> the size of the output vector. Ouput size will be at least length-2 for finite input.
trans

<scales::trans> an invertible transformer.

Details

Breaks are generated by transforming the input range to trans domain, generating a regular sequence of size n for the transformed range, then inverting the transform.

The input range must be finite for both the input domain and the trans domain. If input is not finite, an empty vector is returned.

Log transformation

Description

Applies a log transform on the input: y = log(abs(x), b), where:

  • x is the input vector

  • b is the log base

Usage

log_trans(base = exp(1))

Arguments

base

<number> The log base

Details

If x is negative, the result is multiplied by -1.

This transform requires that the input range doesn't cross zero. Transforming an input that crosses 0 will succeed and give predictable output, but its inverse will not, due to unsigned 0 (i.e. -1 * log(1) == log(1)).

See Also

Other transform: power_trans(), symlog_trans()

Mapbox access token

Description

A mapbox access token is required for rendering the mapbox basemap (regardless of tiles used) and mapbox services (tiles). To use a basemap, you need to register for a mapbox account. Mapbox has a generous free tier.

Each rdeck map rendered equates to a map load for web.

Usage

mapbox_access_token()

Details

The mapbox token is read from the following locations (in order):

  • getOption("rdeck.mapbox_access_token")

  • Sys.getenv("MAPBOX_ACCESS_TOKEN")

  • Sys.getenv("MAPBOX_TOKEN")

RDeck proxy

Description

Creates an rdeck() interface for asynchronous updates of a pre-rendered rdeck map in Shiny apps.

All rdeck props can be updated through the proxy (NULL values will be discarded), layers that are added to the proxy (e.g. rdeck_proxy %>% add_h3_hexagon_layer()) will be merged with pre-rendered rdeck layers.

Layers are merged by their id. Matched layers will be updated in place, new layers will be appended and hence drawn on top of all existing layers. For layer updates, you may omit the data prop to avoid re-serialising unchanged data. All other props will assume their defaults if omitted.

Shiny bindings for rdeck

Description

Output and render functions for using rdeck within Shiny applications and interactive Rmd documents.

Usage

rdeckOutput(outputId, width = "100%", height = "400px")

renderRdeck(expr, env = parent.frame(), quoted = FALSE)

Arguments

outputId

output variable to read from
width, height

Must be a valid CSS unit (like '100%', '400px', 'auto') or a number, which will be coerced to a string and have 'px' appended.
expr

An expression that generates a rdeck
env

The environment in which to evaluate expr.
quoted

Is expr a quoted expression (with quote())? This is useful if you want to save an expression in a variable.

Rescale center

Description

Re-centres a scale to have a defined centre / midpoint. This is the rdeck equivalent of scales::rescale_mid().

centring an rdeck scale creates a new scale with the output palette or range centred at center. This is similar to creating a diverging scale; the key difference is that the output palette or range remains linear (with respect to the breaks) and is truncated on the side that is closest to center. This is useful in creating difference layers, where the output palette or range represents distance from the centre.

Usage

rescale_center(scale, center = 0)

Arguments

scale

<scale> a scale object
center

<number> the center of the scale input

Centring vs Diverging

The plot below shows how rescale_center() and rescale_diverge() distort the scale output. The input scale in this case is power_scale(limits = -36:4); this scale is centred and diverged at 0.

The plot on the left shows the mapping between the input -36:4 (x axis) and output 0:1 (y axis). The plot on the right is a linear representation of the left and is the space that rdeck works in. The input -36:4 transformed with power_trans() and rescaled to 0:1. This plot has been included because it's (hopefully) easier to understand.

In the unaltered scale, we see that 0 is mapped to 0.75 in the output, which would be the colour at 0.75 on a colour ramp (e.g. scales::colour_ramp(viridis::viridis(256))(0.75)).

When applying rescale_center() we see that gradient of function has become y = 2/3x in the linear scale, which is 2/3 * scales::rescale(trans$transform(x)) for our data. For rescale_diverge() we see a piecewise scale with the break at center; both sides of center have a different gradient (y = 2/3x and y = 2x - 1) and the full range of y is used.

The colour ramp plot shows the effect rescaling has on a colour palette (in this case viridis).

Other scales: rescale_diverge(), scale_category(), scale_identity(), scale_linear(), scale_log(), scale_power(), scale_quantile(), scale_quantize(), scale_symlog(), scale_threshold()

Examples

# create a sqrt scale that is centered at 0
sqrt_centered <- rescale_center(
  scale_color_power(col, limits = -36:4),
  center = 0
)

# create a discrete symlog scale that is centered at 5
symlog_centered <- rescale_center(
  scale_color_threshold(col, limits = -100:100, breaks = breaks_symlog()),
  center = 5
)

Rescale diverge

Description

Creates a diverging scale with defined centre / midpoint. Similar to rescale_center(), key difference is the output palette / range is piecewise linear (with respect to breaks) and the entire output range is always used.

Usage

rescale_diverge(scale, center = 0)

Arguments

scale

<scale> a scale object
center

<number> the center of the scale input

Centring vs Diverging

The plot below shows how rescale_center() and rescale_diverge() distort the scale output. The input scale in this case is power_scale(limits = -36:4); this scale is centred and diverged at 0.

The plot on the left shows the mapping between the input -36:4 (x axis) and output 0:1 (y axis). The plot on the right is a linear representation of the left and is the space that rdeck works in.

Scale category

Description

Creates a categorical scale. Categorical scales map input values defined in the set of levels to colours (or values). Input values not in the set of levels are assigned unmapped_color (or unmapped_value).

Usage

scale_color_category(
  col,
  palette = scales::brewer_pal("div"),
  unmapped_color = "#000000",
  levels = NULL,
  unmapped_tick = NULL,
  tick_format = NULL,
  col_label = "{.col}",
  legend = TRUE
)

scale_category(
  col,
  range = 0:1,
  unmapped_value = 0,
  levels = NULL,
  col_label = "{.col}",
  legend = TRUE
)

  • vector of RGBA hex colours,

  • a palette generator function, taking a length parameter, or

  • a palette ramp created from scales::colour_ramp()

A scales::colour_ramp() interpolator is created from the input palette.
unmapped_color

<color> The colour representing unmapped levels.
levels

<factor | character | logical> The category levels. If NULL, will be populated from input data. The order of the levels is determined by levels() for factors & unique() otherwise.

If there are more levels than colours (or range values), the palette (or range) is interpolated.
unmapped_tick

<string> The tick label of the unmapped category. If not NULL and legend == TRUE, the unmapped category will appear at the bottom of the legend.
tick_format

<function> A label function taking a vector of ticks returning formatted ticks.
col_label

<string | function> A template string or a label function for customising the column name in the legend.

  • if col_label is a string, {.col} may be used to represent the col name

  • if col_label is a function, the function must take a single argument: the col name

legend

<boolean> Indicate whether the legend should be displayed for this scale.
range

<numeric> The output range of the numeric scale. Must be length >= 2. A stats::approxfun() interpolator is created from the input range.

Other scales: rescale_center(), rescale_diverge(), scale_identity(), scale_linear(), scale_log(), scale_power(), scale_quantile(), scale_quantize(), scale_symlog(), scale_threshold()

Scale identity

Description

Creates an identity scale; a special case of a linear scale, where input is mapped to itself (input limits = output range). An identity scale is useful in cases where input data is already expressed in a visual representation (e.g. a line width) and should be used as-is.

Usage

scale_identity(col, na_value = 0, col_label = "{.col}", legend = TRUE)

Arguments

col

<name | string> The name of the column containing data to be scaled. Must be a valid input to rlang::ensym(); either a named column (non-standard evaluation), a string. Supports tidy-eval.

<number> The output value for NA input values.
col_label

<string | function> A template string or a label function for customising the column name in the legend.

  • if col_label is a string, {.col} may be used to represent the col name

  • if col_label is a function, the function must take a single argument: the col name

legend

<boolean> Indicate whether the legend should be displayed for this scale.

Note

Identity scales are almost equivalent to an accessor to a numeric column; differences are:

  • NA is replaced with na_value

  • May render a numeric legend

Scale power

Description

Creates a continuous power scale, where input values are transformed with power_trans(exponent) before calculating the output.

Power scales can be useful in transforming positively skewed data. A square-root or cube-root scale can be helpful in dealing with right-skewed data.

A square-root scale can be defined with scale_power(exponent = 0.5, ...) (the default). A square-root scale is a good choice for scaling the radius of point data, as this would result in a linear scale for the area of each point.

Scale quantile

Description

Creates a threshold scale, where threshold breaks are computed from the given quantile probs.

Quantile scale legend ticks will be quantile values at each quantile break (including limits), not the quantile probabilities at each break. This can be overridden in tick_format.

Example: tick_format = function(x) as.character(probs).

Usage

scale_color_quantile(
  col,
  palette = scales::viridis_pal(),
  na_color = "#000000",
  probs = seq.int(0, 1, 0.25),
  data = NULL,
  tick_format = format_number,
  col_label = "{.col}",
  legend = TRUE
)

<number> The output value for NA input values.

Note

As the quantiles are computed from input data, quantile scales are incompatible with layers that load data from a url (e.g mvt_layer). If quantiles for remote data are known, a quantile scale can be constructed manually with scale_threshold().

<numeric | function> The threshold breaks of the scale. The scale palette or numeric range are linearly interpolated (by length) and mapped onto breaks. Breaks outside the limits of the scale are discarded.

If not NULL, breaks must be either:

  • a numeric vector

  • a breaks function, taking a numeric vector argument (e.g. breaks_linear())

Breaks must be in increasing order. Each break will be present on the legend for colour scales.
tick_format

<function> A label function taking a vector of ticks returning formatted ticks.
col_label

<string | function> A template string or a label function for customising the column name in the legend.

  • if col_label is a string, {.col} may be used to represent the col name

  • if col_label is a function, the function must take a single argument: the col name

legend

<boolean> Indicate whether the legend should be displayed for this scale.
range

<numeric> The output range of the numeric scale. Must be length >= 2. A stats::approxfun() interpolator is created from the input range.
na_value

<number> The output value for NA input values.

Note

Threshold scales don't require limits, but breaks_trans() does.

  • normal: Normal blending doesn't alter colours of overlapping objects.

  • additive: Additive blending adds colours of overlapping objects. Useful for highlighting dot density on dark maps.

  • subtractive: Subtractive blending darkens overlapping objects. Useful for highlighting dot density on light maps.

visibility_toggle

<boolean> Whether this layer will appear in the layer selector.
tooltip

<tooltip> Defines the columns (and their order) that will be displayed in the layer tooltip, if pickable == TRUE. Supports tidy-select if a data is a data.frame. Geometry columns are always removed.

Tile json

Description

Intended for use as the data parameter of mvt_layer(). Creates a tile json url from a tileset_id and tile_service. Tile service defaults to getOption("rdeck.tile_service") %||% "mapbox".

The created url will be fetched and parsed with jsonlite::fromJSON().

Usage

tile_json(tileset_id, tile_service = NULL)

Arguments

tileset_id

<string> The tileset_id, may be one of the following

  • a tileset identifier, e.g. "mapbox.mapbox-streets-v8"

  • a tileset identifier.json, e.g. "mapbox.mapbox-streets-v8.json"

  • a url, e.g. "mapbox://mapbox.mapbox-streets-v8", or "https://mytileserver/tileset"

tile_service is unused if a url is supplied.
tile_service

<string> The tile service name, defaults to 'getOption("rdeck.tile_service") %||% "mapbox".

Note

Authentication via mapbox_access_token() occurs when tile_service = "mapbox", or tileset_id uses the mapbox scheme (i.e. mapbox://).

Examples

## Not run: 
tile_json("mapbox.mapbox-streets-v8", "mapbox")
tile_json("mapbox.mapbox-streets-v8.json", "mapbox")
tile_json("mapbox://mapbox.mapbox-streets-v8")
tile_json("mapbox://mapbox.mapbox-streets-v8.json")
tile_json("https://mytileserver/tileset.json")
tile_json("tileset.json", "https://mytileserver")
