Hi,
Thank you both for the suggestions .... it seems i have to send the plot twice
since i cannot have 2 devices active in the same time ..... I Knew about
savePlot but this saves jpf only at 72 dpi and i wanted a better resolution for
jpg files. I will look into dev.copy2pdf, maybe i can have the jpg device open,
save the plot there and after use dev.copy2pdf to get my pdf.
Again, thanks,
