Thanks for the help.
As indicated into the R-admin manual, it was an ubuntu install problem.
But it only shows in R, as I do not use special fonts usually.

Dear all,
I am having problem on plots in R for some cases.
Your machine has Cairo: Cairo-based X11 devices do not use those
fonts. So it seems you have done something you have not shown us.
The fix is to use the Cairo-based X11 devices. See the R-admin manual
for more details.
For example:
plot( 1:10 )
text( 1:10, letters[1:10], cex = 1)
works well but :
plot(1:10)
text(1:10, letters[1:10], cex = 0.9)
returns :
Erreur dans text.default(1:10, letters[1:10], cex = 0.9) :
impossible de charger la police X11
-adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, de face 1 et de taille 11
(sorry for the french).
But it is very easy to set LANGUAGE=en to get American English
messages ....
In this message, for other cases the function may changed (it can be
axis( ) for example) but it always a font problem.
I encountered this issue various times (with more complicated graphics).
I'm working on ubuntu 12.04 with R 3.0.1 (2013-05-16).
The capabilities function returns me:
jpeg png tiff tcltk X11 aqua http/ftp sockets
TRUE TRUE TRUE TRUE TRUE FALSE TRUE TRUE
libxml fifo cledit iconv NLS profmem cairo
TRUE TRUE TRUE TRUE TRUE FALSE TRUE
I think this may be an issue with my installation, but I could not
figured out what was the missing package.
I tried this on other computers. I did not see the same bug.
Thanks in advance for the help,
Alice
