Hello I was wondering if anyone has been able to change the pch value for
points in 3dplot()?  I am able to change point colors just not symbol types.
 I have included a portion of my code below.  I realize this won't work
outside of my script, but thought, maybe there is something obvious that I
am doing wrong.   Also is it possible to utilize the interactive feature of
3dplot in a powerpoint, perhaps there is some sort of file format that the
graph could be exported to?  Any suggestions would be very much appreciated.
 Thanks in advance,


library(rgl, pos=4)
plot3d(subset(Dataset$PC1, source=="ashe_amphib"), subset(Dataset$PC2,
source=="ashe_amphib"), subset(Dataset$PC3, source=="ashe_amphib"),
xlim=c(-5,7), ylim=c(-5,3), zlim=c(-4,7), xlab="PC1", ylab="PC2",
zlab="PC3", col=1, pch=1)
points3d(subset(Dataset$PC1, source=="ashe_ZAS"), subset(Dataset$PC2,
source=="ashe_ZAS"), subset(Dataset$PC3, source=="ashe_ZAS"), col=2, pch=2)
points3d(subset(Dataset$PC1, source=="earlies_gap"), subset(Dataset$PC2,
source=="earlies_gap"), subset(Dataset$PC3, source=="earlies_gap"), col=3,
pch=3)
