In Centos 7 systems, I wrote a script that runs on the cron and I notice some package updates and installs fail like this:Error : .onLoad failed in loadNamespace() for 'iplots', details: call: .jnew("org/rosuda/iplots/Framework") error: java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it. Error: loading failed Execution halted ERROR: loading failed * removing ‘/usr/share/R/library/iplots’ * restoring previous ‘/usr/share/R/library/iplots’ I can log in interactively and run the same install successfully. I understand I need something like xvfb to simulate an X11 session, but I don't understand how to make it work. Can one of you give me an idiot's guide on what to do? pj
I don't know if iplots offers this, but a package should be able to work in a non-X11 environment. rgl does it by checking the RGL_USE_NULL environment variable.
