For all those few of you who care about weird statistical visualization software, I've finally made available a "test" release for R-Orca.  There are 
examples of a 2-d variable selection plot (i.e. 2-d straight projection, with selection of the 2 variables to view), a GrandTour plot, and a Simplicial data plot.  The points of interest are the ability to brush and select from the command line, etc.

Requires Duncan's recent SJava for "stability" under Linux, I've heard reports that it has always been stable under Microsoft Windows.  I don't have a Mac, so am clueless as to whether it works.

D/L the rorca package and test.R example from


I'd appreciate any comments.  For examples of visualizations that I've implemented, you might "checkout" the orca distribution and look in the examples directory.  The java code "ports" in a straightforward way from Java to R.

Really straightforward, thanks to Duncan :-).

I've not provided linked-views examples yet, but hope to do that next week, if nothing interrupts.
