Hi, I am trying to transition a system based on dynamic image generation (via R) from our development system to a production environment. Our R script functions as expected when run by a regular user. However the script dies when calling the png() function, when started by the webserver user.
Here are some details >sessionInfo() R version 2.9.2 (2009-08-24) i686-pc-linux-gnu locale: C attached base packages: [1] stats graphics grDevices utils datasets methods base The script gets to this line: png(file=filename, width=600, height=400) and then dies. It leaves an empty PNG file where it should be, however it never finishes the file. If I replace png() with pdf() an output file is generated and closed by dev.off() as expected. It seems like the environment is setup just as when started by a regular user, specifically the LD_LIBRARY_PATH variable. This behavior suggests that R is encountering an error, and stopping. However there is no reporting of the error. Is there any way to get more verbose error reporting?
