Re: [R] saving png images and X11
Hi Bogdan, If we take the error message seriously, it may be that the initial X11 image was never displayed. When this very suspicious black box function tried to transfer the image to a PNG file, it wasn't there or the function couldn't find it.

Is this a question or a statement that png('file.png', type = 'cairo');
plot(1,1); dev.off() doesn't produce any files for you?
What's the output of capabilities() and sessionInfo() in this build of
R?

This is rather OS-dependent. You should read [1] and if if you need more help consider asking in one of the OS-specific mailing lists mentioned in the Posting Guide. https://cran.r-project.org/doc/manuals/r-release/R-admin.html On February 25, 2022 4:33:38 AM PST, Bogdan Tanasa wrote: >Dear all, > >I am using a R package that renders the png images.
