quartz.save()

Hi Peter & Ricardo

The same thing can be done in 2.7.0 with:

quartz(type="pdf", file="/Users/username/wherever")
plot(0,0)
dev.off()

help(quartz) for additional options
I don't think so: that does not save the current plot.  You could adapt 
dev.copy2pdf() to come very close (or just use it -- R's pdf device will 
copy well enough unless you need exotic fonts).

I think the changes needed are from

     oc$device <- pdf
     oc$onefile <- FALSE
     if (is.null(oc$paper))
         oc$paper <- "special"
to
     oc$device <- quartz
     oc$type <- "pdf"

but I'm not sitting in front of a Mac.

(Had quartz(type="pdf") been working at feature freeze for 2.7.0 we might 
have made this an option in dev.copy2pdf, but it was broken until 
recently.)

Best wishes,

Todd

Hello all,

I'm having trouble with the quartz.save(), I know this is an
undocumented function, and perhaps it is to be removed in 2.7.0.
However, I find it very useful though I have been having trouble with
it lately.

Specifically, I get:

quartz()
plot(0,0)
quartz.save('temp.pdf')

Error in .Call("QuartzSaveContents", device, file, type, list(...)) :
  C symbol name "QuartzSaveContents" not in load table

I know that quartz.save() has been discussed recently on the list, but
I didn't see this particular issue addressed.

Thanks

Peter

R GUI r5072
I'm getting exactly the same behavior here. Same R.app GUI, r5072,
version.string R version 2.7.0 beta (2008-04-12 r45280).

And I also find this function really useful. Sorry, I've not followed
previous discussions, so I am not aware of possible alternatives. Accept
my apologies if they are quite obvious.

Thanks,

Ricardo
