Problems with png()

From: Laura Quinn

Sorry!

Tried to save the .png from both R-1.9.1 and R-1.8.0 to no avail. I am
running R-1.9.1 on SusE 9.0, and R-1.8.0 on Debian.

I have tried to view the images with Gimp and Kview (on both 
systems), to
no avail.

More details please, we cannot help otherwise.
At least version of R, operating system, and version of 

libpng, as well

as the program that told you the file is corrupted ...

Uwe Ligges

for each image plot I produce. Unfortunately when I have 

tried this I am

unable to open the files, and am told they are corrupted.

I have tried to use the jpeg() function but have the same 

problem. The only way I have managed to

export a graphic successfully is as dev.copy2eps. Aside 

from producing

unwieldy files, this is also unhelpful as I at m hoping to 

create a movie of

the images via ImageMagick.

Any suggestions?

Thanks in advance,
