Dear All,
is there a way to plot to a connection? I mean, I would like to do
something like
> tc <- textConnection("foo", "w")
> png(tc)
> plot(...)
> close(tc)
According to the documentation of the Cairo package, this should work
with CairoPNG() (among others), but all I get is
> tc <- textConnection("foo", "w")
> CairoPNG(file=tc)
Error in Cairo(width, height, type = "png", file = filename, pointsize
= pointsize, :
file must be a filename. to support writing to a connection,
recompile R and Cairo with the R Connection Patch.
Anybody knows what is the "R Connection Patch"?
Btw. is there any particular reason that the png(), jpeg(), etc.
devices do not work with connections?
Thanks,
Gabor
