[BioC] probelms with hexbin (Solaris, R1.9, BioC 1.4)

Hi Ariel,
The segmentation fault may not be hexbin, but may be due to something in
your compile of R.
We have a sun here running solaris 9 so I can check with our sysop if I
can compile R-2.0 
and hexbin 1.0.10 using 64 bit. I did it a while back for an older
version on Solaris 8 and
had no problems which is why I suspect it is your whole compilation. Can
you try just using 
plot and polygon and changing the pars and see what happens? If that
works than
the next culprit is the hexbin fortran code, and from there .....

Thanks
Nicholas
