In zlog: Z(log) Transformation for Laboratory Measurements

Z(log) Depending Color

Description

This function provides a color gradient depending on the zlog value as described in Hoffmann et al. 2017. The colours are only roughly equal to the one found in the article.

Usage

zcol(x)

Arguments

Value

character, of length(x) with the corresponding color hex code.

Examples

z <- -10:10
image(matrix(z, ncol = 1), col = zcol(z), xaxt = "n", yaxt = "n")
text(seq(0, 1, length.out=length(z)), 0, label = z)
