Generate a Continuous Colour Palette Function

Returns a function that maps numeric values to colours based on the current or specified palette. Works with ggplot2 via scale_colour_gradientn / scale_fill_gradientn.

Usage

PaletteContinuous(n = 256L, palette = NULL)

Arguments

n

Integer. Number of colours to generate. Default 256.

palette

Character or character vector. Palette specification (see SetPalette). If NULL, uses the global palette.

Value

A character vector of n hex colours.

Examples

cols <- PaletteContinuous(10)
plot(1:10, col = cols, pch = 19, cex = 3)


cols <- PaletteContinuous(10, palette = c("blue", "white", "red"))
plot(1:10, col = cols, pch = 19, cex = 3)
