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

[Joris Meys]

Hi Tiago,

Without knowing which package you're talking about or a link to the check results, it's impossible to know whether that warning is a proper one or a side effect of something else. 

In general though: it is well known that relying on devtools is not enough for a good CRAN submission. The guidelines for CRAN clearly state :

"Please ensure that R CMD check --as-cran has been run on the tarball to be uploaded before submission. This should be done with the current version of R-devel (or if that is not possible and explained in the submission, current R-patched or the current release of R.)"

So before submitting a package to CRAN and after running your devtools:: check_etc, open a terminal and run the following commands:

R CMD build path_to_pkg_folder
R CMD check --as-cran package_version.tar.gz

The --as-cran is important, as is doing so against a R-devel. I use devtools myself extensively, but these checks have to be done outside the RStudio ecosystem to be sure.

Kind regards
Joris

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

Dear all,

In the last submission of my package the CRAN team has suggested including
some references in the description field of the DESCRIPTION file.
When I submitted it to CRAN it did not pass the incoming checks
automatically and I got the following WARNING.



Quitting from lines 108-117 (vignettes_metan.Rmd)

Error: processing vignette 'vignettes_metan.Rmd' failed with diagnostics:

Unknown colour name: transparent



It seems that this warning is related to a function with the argument
'col.segm.gen = "transparent"'.

I don't changed anything in this function and in the last submissions no
warning was related.

For curiosity I ran:

> col2rgb("yellow")

      [,1]

red    255

green  255

blue     0



> col2rgb("transparent")

      [,1]

red    255

green  255

blue   255



No warnings or errors were observed while running devtools::check_rhub(),
devtools::check_win_devel(), and devtools::check_win_release()

Any suggestion?

Best,

Tiago
