Hi Henrik,
Running the commands
Since there are several different PNG drivers for R, aroma tries to
automatically find one that works. Try the following in a fresh R
session:
library("aroma.core");
pngDev <- findPngDevice(transparent=FALSE);
pngDev("foo.png", width=840, height=640); plot(1:10); dev.off();
Is foo.png empty? Wha

files
and I'm seeing a warning message but as yet have been unable to figure out

The warning is
libpng warning: Application built with libpng-1.2.26 but running with 1
