I am trying to run an R script to create a .png file containing a tree map on a
headless Linux server using Xvfb. When I try to run tmPlot, I get the
following errors and warnings:
Error in grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size 9 could
not be loaded
Calls: tmPlot ... <Anonymous> -> widthDetails -> widthDetails.text -> grid.Call
In addition: Warning messages:
1: In grid.Call.graphics(L_text, as.graphicsAnnot(x$label), x$x, x$y, :
X11 protocol error: BadMatch (invalid parameter attributes)
...
etc. (complete error message below)
The .png file does contain a partially constructed graph. When I try something
simple like plot(x,y) I get a plot with warnings.
The results from capabilities() and X11Fonts() (see end of message) suggest to
me that it should work.
Any idea what is happening and how to fix the problem (or work around it)?
Thanks,
Jay
