[R] X11 fonts and Ubuntu

[Rich FitzJohn]

Hi,

I have observed this as well (Debian etch, R 2.4.0), with "small" cex
values when drawing text.

My LANG environment variable was set to "en_NZ.UTF-8"; setting this to
"C" or "en_NZ" seems to prevent the error occuring.  I presume my
installation is missing a few fonts, yours may be too.

HTH,
Rich

 Setting the environment variable LANG=C before running R seems to
work as a workaround (normally this is en_NZ.UTF-8
