Dear David,
In fact just updating R seems to have fixed the problem. There's a lesson.
Thanks a lot,
George

Dear all,
I am trying to write figures directly to a file using the jpeg()
function.
this_ylab=expression(paste(P,sep=)~lambda)
this_xlab=expression(rho)
jpeg(file_name.jpeg,width=100,height=100,units=mm,res=300)
Try instead something like:
quartz(file=file_name.jpeg, type=jpeg, width=7,height=7)
And follow-ups should go the R-SIG-Mac mailing list. And please update
your installation of R.

plot
(input_values
,output_values,pch=16,cex=cex_pt,xlab=,frame.plot=T,ann=F,axes=F)
axis(side=2)
axis(side=1,labels=T,xlab=)
mtext(this_xlab,side=1,line=4,cex=2)
mtext(this_ylab,side=2,line=3,cex=2)
dev.off()
However, I get the following error message:
Error in mtext(this_xlab, side = 1, line = 4, cex = 2) :
Metric information not available for this device
I could put the argument specifying the x-label in the plot
function but
then I don't control where it goes. When I have used the tiff()
function
instead I don't have this problem.
I am using R 2.11.1 on Mac OS X 10.7.3
Thanks,
George
