Map Score to Black and White Color

Maps a numeric input value to a color from a black-white gradient palette. Values are mapped to a 1001-color palette where -2 maps to black and +2 maps to white.

Usage

mapbw(x, my_palette2 = NULL)

Arguments

x

Numeric value to be mapped to a color (typically between -2 and 2).

my_palette2

Color palette vector (should have 1001 colors). Default uses black-white gradient.

Value

A color from the black-white palette as a hex code.

Examples

my_palette2 <- grDevices::colorRampPalette(c("black", "white"))(1001)
color <- mapbw(1.5, my_palette2)
color <- mapbw(-1, my_palette2)
