Jack,
There is no pch= argument for plot3d() or points3d(). You can change the
color and the size of the symbols. Or you can use characters as symbols
using text3d(). I found that suggestion by searching the rhelp archives.
It is helpful to share code that will work.
x <- c(-4, -2, 0, 2, 4)
y <- c(-4, 0, 2, -3, 1)
z <- c(-2, 6, -3, 5, 5)
library(rgl)
plot3d(x, y, z, xlim=c(-5,7), ylim=c(-5,3), zlim=c(-4,7), xlab="PC1",
ylab="PC2", zlab="PC3", col=1, type="n")
text3d(x, y, z, col=1, "o")
text3d(x+1, y+0.5, z, col=2, "*")
text3d(x-0.5, y, z-0.5, col=3, "w")

[R] change pch in 3dplot, export graph
Sent by:
r-help-boun...@r-project.org
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)
