Dear all,
I have recently submitted a package to Bioconductor and during the
review some issues with semi-transparency in output plots from two
functions have been identified. The warning message was:
In grid.Call.graphics(C_points, x$x, x$y, x$pch, x$size) :
semi-transparency is not supported on this device: reported only once
per page
(https://github.com/Bioconductor/Contributions/issues/1828#issuecomment-763069622).
This warning appears on R Under development (unstable) (2021-02-20
r80030), Platform: x86_64-pc-linux-gnu (64-bit), Running under: Ubuntu
20.04.1 LTS, but everything seem to work fine on Windows and Linux with
R version 4.0.3 as well as Windows with R devel version (2021-02-27
r80043). I could find other examples of functions producing same
semi-transparency warning (e.g.
https://tinyheero.github.io/2015/09/15/semi-transparency-r.html), where
solutions are for user to change their ~/.Rprofile file. Is there
anything that can be done with this issue in the code of the package
functions or in the vignette?
Thank you for any suggestions!
Petra
