This is probably because R on a server requires an X11 framebuffer since your process is not able to open an X11 server connection while it's running.

Hi,
I am trying to wrap the qvalue R package in a script (as I have already done for a dozen), but this time I have repeatedly the same error "In fun(libname, pkgname) : no DISPLAY variable so Tk is not available" or "Loading Tcl/Tk interface ... done" (and red, desperately red box).
I already had this type of bugs and fixed them by using the suppressWarnings or suppressMessages R methods. But this time, no way. I really don't need the Tcl/Tk interface and I am not using it with qvalue... frustrating. (my code run into R in command lines like a charm)
Any clue to shut off Galaxy and get this miserable pvalue vector output ?

PS. I browsed the net, found traces of problems similar to mine, but unfortunately no trace of solutions.
