Hi, I'm trying to run batch R scripts that is triggered online with PHP code: exec(R --no-save -q < myscript.r > output.txt 2>&1); However, as there are some R libraries, e.g. qvalue, webbioc needs X11 (tcltk) loaded, I got the following errors: Loading Tcl/Tk interface ... Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/usr/local/lib/R/library/tcltk/libs/tcltk.so': /usr/lib/libXft.so.2: undefined symbol: FT_GlyphSlot_Embolden Error : .onLoad failed in 'loadNamespace' for 'tcltk' Error: package/namespace load failed for 'tcltk' Execution halted I have no problem to run the script on the shell when X11 is lauched. How do I launch X11 before running R scripts in batch from the web? Is there a way to avoid loading tcltk when loading R libraries like qvalue and webbioc? As far as I remember, the old versions of qvalue and webbioc do not require tcltk. Thanks Amy.
