Hi,

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?

Thanks
