[R] X11 Fonts sizes

[Wolfgang Waser]

In postscript graphs (pointsize = 10, different sizes in graph adjusted via 
cex) I would like to use different font sizes but get the following warning 
message:

Warning messages: 
1: X11 used font size 8 when 9 was requested 
2: X11 used font size 8 when 7 was requested 
3: X11 used font size 8 when 5 was requested 

This is probably not a R but a X11 problem, nevertheless I would be most 
obliged for any help how to actually use font sizes 9, 7, and 5 and others.


Sincerely

Wolfgang Waser
