I cannot generate png files running R2.2.1 on a SunOS 5.9 machine. See
below. I did a search on this problem and people who have virtually the
same error have solved the problem by installing or updating libpng .
We downloaded libpng from Sun but still the problem remains. Does a path
within R need to be set to this file or does the problem indicate that
libpng was not installed properly? I have no problems running on
various Linux OS's or a SunOS 5.8 machine. I appreciate any help on
this issue. We are using R2.2.1
