Hello I'm trying to use rpy with latest R (2.2.0), but unfortunately it seems there is some kind of undefined symbol in grDevices.so (utf8locale) Within python, this message appears: >>> import rpy Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/usr/local/lib/R/library/grDevices/libs/grDevices.so': /usr/local/lib/R/library/grDevices/libs/grDevices.so: und...

Is it possible to configure and build an R without any graphics support. I..e no grDevices or graphics packages? I tried "--with-x=no --with-cairo=no --with-grDevices=no --with-graphics=no" but it is still building grDevices. My problem is that I am using experimenting with a compiler that cannot compile the Objective-C file, qdCocoa.m, and I don't need graphics for...

It appears that the chromatic adaptation feature of `grDevices::convertColor`is broken, and likely has been for many years.? While a little surprising, it is an obscure enough feature that there is some possibility this is actually broken, as opposed to user error on my part.? If it turns out to the latter, I apologize in advance for spamming this list. Consid...

Oftentimes, I see graphs on the web that *look* like they've been produced by R, but I can never be sure. Or can I? I notice that PostScript files include a "%%%Creator: R Software" line, but do R graphics drivers encode any identifying information in GIF or PNG files more commonly used on the web? And of so, would such evidence necessarily be obliterated in post-processing (e.g

Hi everyone, I wanted to draw your attention to a new post on the developer.R-project.org blog: https://developer.R-project.org/Blog/public/2019/04/01/hcl-based-color-palettes-in-grdevices/ A new function grDevices::hcl.colors() greatly extends the color palette functionality available in base R. Also, the defaults in the heatmap functions image() and filled.contour() have been adapted accordingly. Feedback is welcome, especially regarding potential problems with the changed def...

It appears that grDevices (and perhaps other R libraries) is built without passing C_VISIBILITY to PKG_CFLAGS (-fvisibility=hidden), while other libraries (e.g. utils) do use the flag. This results in potential crashes on linux in situations like using embedded R in another application that happens to export a symbol named...
