When using color.id from the plotrix package, is it possible to get ONLY a single colour returned not a vector of colours? see this example:
color.id("#A1A295")
this returns: "gray62" "grey62"
Is there a way (or another package) that simply returns a single colour name?
Thanks.
Here is vectorized function based on what Limey said.
get_color_name <- function(color_hex) {
out = vector(length = length(color_hex))
for(i in seq_along(color_hex)) {
out[i] <- color.id(color_hex[i])[1]
}
out
}
get_color_name(rainbow(5))
>[1] "red" "yellow2" "springgreen2" "dodgerblue2" "magenta2"
get_color_name("#A1A295")
>[1] "gray62"
