Re: [R] Some problems with X11
Yuelin Li and Joerg van den Hoff,
Thank you very much for your emails. Apparently, I found that xorg.conf
has all the directories related to fonts specified as
/usr/share/X11/fonts/. However, the files are located in
/usr/share/fonts/X11/. I manually changed the paths for each line and
tried R again. It is now working!
Thanks a lot

[R] Some problems with X11
Hi,
I am really new with R, so I don't know anything about it. I have
written a script (attached) which tries to do really basic stuff (such
as computing basic statistics and basic plots). When I try to plot a
histogram and pairs, for example, I get the following message:
> source("project.R")
Loading required package: sp

Analysis of geostatistical data
For an Introduction to geoR go to http://www.est.ufpr.br/geoR
geoR version 1.6-13 (built on 2006/12/26) is now loaded
-
Error in title(main = main, sub = sub, xlab = xlab, ylab = ylab, ...) :
X11 font at size 8 could not be loaded
>
I have seen some threads about this problem, though none of them really
states what should be done in order to solve that problem (At least it
was not clear for me!).
This is the R version I have:
> version
_
platform i486-pc-linux-gnu
arch i486
os linux-gnu
system i486, linux-gnu
status
major 2
minor 4.1
year 2006
month 12
day18
svn rev40228
language R
version.string R version 2.4.1 (2006-12-18)
I am also running R on a Ubuntu Linux Edgy distro. The interesting thing
is that I have this problem on my desktop only. I also have Ubuntu Edgy
installed on my laptop and it is working just fine!
Thank you
R
