Hello,
A reproducible example would be nice.
Anyway, with "lattice::xyplot", you can store, then print the figure, in
order to write it into a file:
> xyObj <- xyplot(...)
> postscript(...)
> print(xyObj)
> dev.off()
Regards,
Pascal

Hi,
When I was using the regular plot() function, I added this:
--8<---------------cut here---------------start------------->8---
if (!is.null(file)) {
do.call(tools::file_ext(file),list(file = file))
on.exit(dev.off())
cat("writing",file,"\n")
}
--8<---------------cut here---------------end--------------->8---
to the beginning of each of my functions which plotted anything.
now that I am using lattice::xyplot to plot multiple lines, the above
code does NOT result in the plot being written to a file.
why?
I trued passing file=file to xyplot but that appears to be ignored too.
so, how do I tell lattice::xyplot to write charts in png files?
thanks!
