xrtplot
+++++++


This library provides access to the 3d plot functions of the XRT toolkit.

This library is _NOT_ intended as a final solution to the lack of 3d plots
in R, because it uses commercial components, which might be not a good
idea in a freeware project, as R is. 

But if you own a copy of XRT you can use it now for 3d plots within R.

Currently XRT for Linux is shipped with the S.u.S.E. Metrolink Motif 2.x
CDs.

(there are evaluation copies available, I think)


Currently this library uses one of the demo programs (feedback3d) shipped
with XRT. 

I think it could be possible to write a special "plot3d" program for R,
starting from the sources of these demos, the copyright notice in the demo
sources (cited below) seems to allow this.  It would even be possible to
distribute the resulting binaries (statically linked) freely.

But, as alreasdy mentioned above, a better solution to the 3d-plot problem
in R is to have an implementation based on free tools or libraries!
