Hello, I'm trying to adapt some R code that works on Windows so that it will work on a Linux machine.
The command : png("myFile.png", width=600, height=600) fails claiming that it is impossible to establish a connection with X11. (Error messages are in French, so I'm not pasting them here!) I have libpng installed: >rpm -qa libpng* libpng-1.0.12-2 libpng-devel-1.0.12-2 So I don't understand why R thinks I'm trying to connect to X11. I haven't been able to find many examples of R graphics code specifically for Linux, but I have the impression that if libpng is installed, the graphics commands are identical. The libpng manual is not useful, because it does not mention use of libpng commands in an R environment. I'm using R 2.4.1, which I recently installed. Do I have to install a more recent libpng ? If so, do I have to reconfigure and remake R ? I've also read that no graphics devices are available under R CMD BATCH. Does that really mean that I can't create graphics from some R code that I launch in noninteractive mode? Thanks in advance !
