[R-sig-Geo] package for bidimemsional regression

[Marco Helbich]

Dear list,

Is there a package available, which computes the "bidimemsional regression"? 
For literature see e.g.

Tobler, W: Bidimensional Regression, Geographical Analysis, 26: 186-212.

Friedman, A; Kohler, B 2003: Bidimensional regression: A method for 
assessing the configural similarity of cognitive maps and other 
two-dimensional data. Psychological Methods, B, 468-491

I appreciate every hint!

Best regards
Marco Helbich
