In colorfast: Fast Conversion of R Colors to Color Component Values and Native Packed Integer Format
col_to_rgb R Documentation
Fast conversion of colors-as-strings to a matrix of RGBA integers
Description
This is a faster replacement for grDevices::col2rgb() which uses
a hash lookup of R color names (rather than a linear search).
Usage
col_to_rgb(col)
Arguments
col
Character vector of color names. Supports all R color names
(e.g. "red", "hotpink") and hex colors of the form: "#RRGGBBAA",
"#RRGGBB", "#RGBA" and "#RGB".
Value
An integer matrix with four rows and number of columns
the length of the input.
Examples
col_to_rgb(c("hotpink", "#abc", "#abcd", "#aabb99", "#aabb9980"))
