What were H & W? For png() they are (by default) in pixels, for pdf() in
inches.
You haven't told us your OS, but I guess Mac OS. Please update to R
2.7.0: that offers you two new png() devices for higher-quality plots, and
various other improvements. (If you want to use the cairo-based png() at
other than 72dpi, use R-patched or remember that the pointsize is
mistakenly in pixels.)

I've used to have a script with a barplot command it in, preceded by a png:
png(graph.file,height=H,width=W)
barplot(t,names.arg=breaks[2:(length(t)+1)],tck=gridlines)
-- worked before R 2.6.2. When I tried it in R 2.6.2, which I have for a
while but didn't run with that script, it complained, the margins too large,
and I've googled the messages from our list where neither height nor width
had been specified. Yet here they are specified here.
Not in this email -- very likely they are too small.
Calling same from R GUI draws the nice barplot in Quartz, and replacing png
with pdf or postscript does fine. Other graphs work fine with png. Jpeg
also complains; when I try various values for H or W, still the same -- how
can I subdue the png?
Cheers,
