Dear R users,
I'm currently visualizing my data using scatter3d from the "Rcmdr"
package. I have data points which can be separated in two
classes. Data points from class 'A' should be colourised red and
data points in class 'B' should be colourised 'blue'. No matter
what I try, the data points are always blue.
I attached a (very) minimal example to reproduce my problem.
Thanks,
Philippe
library("Rcmdr")
scatter3d(x=c(1,2), y=c(1,2), z=c(1,2),
groups=as.factor(c(1,2)),
point.col=c('red','blue'), surface=F)
Now that is weird! (I'm not a regular user of Rcmdr.) I didn't
think that rgl would run under the 64 bit R, but there does seem to
be a functioning rgl widow that comes up. Hmmm .... Need to
investigate this further. Looks promising.
Dropping the groups term corrects your color problem, so the colors
are probably <somehow> being derived from the numerical
underpinnings of the group factor.

Hi David,
thanks for your answer. Dropping the groups term does not solve my
problem. After dropping the term both data points have a red colour.
Then it's probably time to compare details from your sessionInfo(),
capabilities(), and system specs. I'm on a Mac running with the R64
GUI and graphics devices vary quite a bit across the range of OSes.
Just to be clear this was my function:
scatter3d(x=c(1,2), y=c(1,2), z=c(1,2),
point.col=c('red','blue'), surface=F)
