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':

Hi folks, Debian 504 64 bit grDevices is NOT on Debian repo $ apt-cache search r-cran | grep grDevices no printout On R $ sudo R > install.packages("grDevices", dependencies=TRUE)) Warning in install.packages("grDevices") : argument 'lib' is missing: using '/usr/local/lib/R/site-library' --- Please select a CRAN mirror for use in this session ---

Hi. I'm not having any luck installing the binary for the new Macintosh OS called "Tiger". I get error messages as below. Can anyone offer me some advice? (PS: I checked the bug list first but a search on "Tiger" turned up nothing so I hope it's OK to post here.) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared

I'm trying to build R 2.4.0 on an IBM P5-570 that's running AIX 5.3. I'm using xlc 7.0, xlc++ 7.0 and xlf 9.1 in 32 bit mode (OBJECT_MODE is 32 in the build environment). The source is the patched version of 2.4.0, downloaded yesterday. Configure options were --prefix, --srcdir, --x-includes, --x-libraries, and --without-readline. Compiler flags were -O2. The make step fails with

(Warning: I'm not an R guy. I'm a Python guy trying to get the R-Python interface working again after some upgrades.) I'm trying to upgrade our numpy/rpy/matplotlib environment (Solaris 10/Intel, Python 2.4). In the process I found I needed to rebuild R (2.1.1) because it was compiled with gcc 3.3.2 and we have since migrated to gcc 3.4.1. I'm using this configure setup:

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 this

Hello everybody,I am having an error while compiling R-2.5.0 on Linux powerpc.

Dear all I've just tried the brand new 'grdevice' option in Sweave but couldn't make it work. When I declare \SweaveOpts{grdevice=pdf} or \SweaveOpts{grdevice=cairo_pdf} trying to plot something simple <<fig=T, echo=T>>= plot(1:10,1:10,main='Some title') @ would result in an Sweave error: 18:16:47.299: 1 : term verbatim 18:16:47.308: 2 : echo term verbatim

If one wants to unload compiled code for a package containing a namespace, my understanding is that .onUnload() should be used, with a call to library.dynam.unload(). This is used in e.g., the stats and methods packages, but it appears to me that the compiled code is not being unloaded when the package is detached(). Am I misunderstanding something?

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

I use mac os 10.3.9 and I've installed in my computer R 2.1.0 (I believe this is the latest R version). Although it works alright when I open R by clicking in the R icon, I cannot use the graphics facility when I open R from a X-terminal window (or x-11 window). In fact, when I try to open R I get the message that I pasted below. Is this a R bug? Is R assuming that I should have the

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 similarly to one defined in R's library, since the runtime linker

Dear all, I am sending a patch for extending pdf device to embed popup text and web links. I implemented this feature by using annotation object, a interactive feature of pdf. You can see a sample code for using this feature in the following, and sample pdf is in

Hi, I am trying to test out the scripts here as a proof of concept http://www.r-bloggers.com/integrating-php-and-r/ However, I am not able to reproduce the output graph in the browser. Rscripts is working fine as I run the command "Rscript /home/username/R/testscript.R 1000" for example, and a png graph is output as expected, and I can output it to any folder where I have permission

Dear all, In grDevices R functions cairo_pdf and cairo_ps it is mentioned that when transparency (alpha channels) are used in vector output, it will rasterize the PDF or postscript exported graph at a resolution of 72 dpi : https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/cairo.html You can see the problem if you try library(ggplot2) cairo_ps(file = "test.eps",onefile =
