Sorry :|

version :
         _                   
platform sparc-sun-solaris2.8
arch     sparc               
os       solaris2.8          
system   sparc, solaris2.8   
status                       
major    1                   
minor    2.2

month    02                  
day      26                  
language R 

example :
    
postscript("pipo.ps")
pipo<-matrix(c(1:12),ncol=4)
par(mfrow=c(1,4))
for (i in 1:4){ plot(pipo[,i])}
dev.off()

well, there's problems with translation from ps to pdf too, so I don't 
think ghostscript matters (?).

thanks for your reply, 
 Mathieu
