[R-pkg-devel] RES: Possible unknown color in r

Hi Joris,
Thank you for your suggestions.
After installing the version v 2.0.2 of "farver" I was able to reproduce the
WARNING.
To fix this issue, I created a simple helper function:
transparent_color <- function() {
  return("#000000FF")
}
And changed "transparent" with "transparent_color()" in my R scripts.
After, I built and check again with 'R CMD check --as-cran
metan_1.2.1.tar.gz' and no longer WARNINGS were observed.
Thanks again,
Tiago

Hi Tiago,

It's indeed that. For some reason col2rgb() knows the unofficial
"transparent". Replace this with the correct value from the vector colors(),
i.e. "white". "transparent" is not mentioned in that vector, so it shouldn't
be used in a package. See also ?rgb2col and ?colors.

Cheers
Joris
