Scale quantize

Description

Creates a discrete quantize scale, with n_breaks linearly spaced threshold breaks between limits. This scale can be thought of as a restricted special case of scale_threshold(), or a discrete scale_linear().

Usage

scale_color_quantize(
  col,
  palette = scales::viridis_pal(),
  na_color = "#000000",
  limits = NULL,
  n_breaks = 6,
  tick_format = format_number,
  col_label = "{.col}",
  legend = TRUE
)

scale_quantize(
  col,
  range = 0:1,
  na_value = 0,
  limits = NULL,
  n_breaks = 6,
  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.
palette	<color|function> The colour palette of the colour scale. Must be a: 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.
na_color	<color> The colour value for NA input values.
limits	<c(min, max)> The limits of the scale's input. If NULL, limits are computed from layer data. Values outside the range of limits are clamped.
n_breaks	<integer> The number of linearly spaced breaks in the scale. 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.
