Dear list,

I do not understand how to get group variables from XGobi into R.
For example, I start with
data(laser)
xgobi(laser)
and in xgobi I brush some points red. Now xgobi creates a group
variable (I did not understand *when* this group variable is created
and how I get it even in xgobi, but, however, suddenly it was
there...). What must I do if I want this group variable as a variable of
R?

Thanx,
Christian

you can have it written out into an ASCII file, 
and must read that into R via scan() or such. 
This is not very convenient, I agree, but the
     R <-> Xgobi
connection is only via ascii files.

Instead of putting considerable effort into the R-xgobi interface,
the real thing will soon be ggobi, a gobi version based on GTK and hence
available for Unix and Windows at least.
