[Rd] Saving a plot in R-LINUX

[Augusto.Sanabria@ga.gov.au]

Vaidotas,

The command 'dev2bitmap(plotname, type="jpeg")'
does the trick too.

Thanks to all those who sent helpful tips. It seems that I
am posting these questions to the wrong list, my apologies!

Regards,

Augusto

What about using dev.copy? Or am I missing something? In windows there is a
context menu when you click with the right mouse button, which lets you
choose how do you want to save the plot. On linux I came up with such
function, which albeit not perfectly but does the job:

d2b <-
function(file="Rplot%d.bmp",height=4,width=4,res=150,which=dev.cur(),...)
{
    if(which!=dev.cur()) {
        cur <- dev.cur()
        dev.set(which)
    }
    else cur <- NULL

 
dev.copy(device=bitmap,file=file,height=height,width=width,point=8,res=res,..
.)
    dev.off()
    if(!is.null(cur))dev.set(cur)
    else dev.set(which)
}

It copies told device (current by default) to bitmap file. This function
could be easily adapted for copying to other formats.

Since the answer was too easy, probably I did not understand question
correctly. In that case please ignore this message.
