Subject: [Rd] scatterplot3d
Message-ID: <39C9B8B9.F8A85481@statistik.uni-dortmund.de>

Hi!

A new version (0.3.3) of scatterplot3d (plots a 3D point cloud
perspectively) is available at
http://www.statistik.uni-dortmund.de/leute/ligges.htm

I am especially interested in bug reports and reports of unexpected
results (always with examples to reproduce the error, please).

Also feel free to send feature requests. 
Some R users (see the parts of two emails below) are missing a function,
which plots a 3D perspective of a matrix. So I am thinking about
creating a new function (based on the code of scatterplot3d, if there
are no more known bugs in it), which does the trick.
