I felt I had to share this gorgeously simple trick for finding the colour name you need in R.
col.wheel <- function(str, cex=0.75) { cols <- colors()[grep(str, colors())] pie(rep(1, length(cols)), labels=cols, col=cols, cex=cex) cols } #then just do: col.wheel("slate") #or: col.wheel("gold") #or whatever.
