This question is more appropriate for the R-help list, as this has 
nothing to do with any BioC package.

Anyway... savePlot() is AFAIK only available on Windows so you will not 
be able to use that function under linux. In addition, I don't think it 
is that common to have libpng installed on linux, so you will likely 
need to install libpng before you will be able to use png(). Check 
capabilities() to see if you have png support.

I don't know if there is a way to tell R that you have libpng installed 
without re-configuring and re-making (I would imagine there is, but I 
don't know how). However, since the only thing that would be added in is 
png support, I would imagine a compile and make would be pretty quick.

HTH,

Jim
