Generate a continuous set of colors

Source: R/color_palettes.R
get_continuous_colors.Rd

Based on a vector of colors provided to col, make these colors continuous (i.e. make it possible for an arbitrary n number of colors to be requested) then return those n colors.
strategy describes how to make these colors continuous:

  • 'interpolate' interpolates provided colors using grDevices::colorRampPalette()

  • 'recycle' - recycles the input color vector across the n requested.

  • 'cutoff' - supply only a maximum of as many colors as exist within the originally supplied vector.

Usage

get_continuous_colors(col, n, strategy)

Arguments

col

character vector. colors to make continuous

n

integer. number of colors to get

strategy

one of 'cutoff', 'recycle', or 'interpolate'. strategy to use when more colors are requested than exist

Value

a vector of colors

Examples

get_continuous_colors(col = "#eb4034", n = 10, strategy = "interpolate")
#>  [1] "#EB4034" "#EB4034" "#EB4034" "#EB4034" "#EB4034" "#EB4034" "#EB4034"
#>  [8] "#EB4034" "#EB4034" "#EB4034"
