[R] Problems with png()

[Laura Quinn]

I am trying to save a series of plots as .png files by using

png(file="myfile.png",bg="transparent")
dev.off()

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,
