I am on Ubuntu 13.10, with R version 3.1.0 beta (2014-03-28 r65330) -- "Spring Dance" (64 bit).
It is a new install and when trying to plot I am getting above error message
Error in title(main = "Test", line = -1) :
X11 font -adobe-helvetica-%s-%s---%d-------*, face 2 at size 11 could not be loaded
This is happening with X11(type="Xlib")
I looked around a bit, but could only find quite old threads. Prof. Ripley replied to a similar issue in 2013 with
See ?X11 and the 'R Installation and Administration Manual'. You are dragging up ancient history (2002). The 'modern' X11 device (from 2007) uses cairographics and does not use X11 fonts. I suggest you take a look at how R was built and ensure that the cairo-based device is available. Further, for a long time most X11 installations have been from Xorg and not Xfree86, and do not generally have a config file.
That unfortunately doesn't help me, because I am using events:
setGraphicsEventHandlers(prompt="Click and drag to zoom, hit q to quit", onMouseDown = dragmousedown, onMouseUp = mouseup, onKeybd = keydown) eventEnv <- getGraphicsEventEnv() getGraphicsEvent()
And those aren't supported on any other device. It is still working on my other machine, so I presume I just need to find fonts somewhere.
How do I install or generate those fonts on Ubuntu?
