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.
