Thanks Jari, My original thought was to write a wrapper for the original FORTRAN code by replacing the file read of data with data passed from R, and then bringing in the results in a list. That would allow sizing the arrays at run-time and eliminating fixed array sizes. I have a copy of

Dear Zoltan, Thanks for the note. The R function I wrote does in fact follow the Roleček et al protocol, and that's partly what motivated the idea to write it up. Lubomír Tichý, Petr Smilauer, and Laco Mucina have all contributed information in the development, but I've still been stymied

Dear List, Earlier this year on an (undoubtedly ill-advised) lark I coded up an R version of TWINSPAN. It's far from a polished package at this point, but the code does run. One of the interesting features is that you can partition a PCO or NMDS in addition to the traditional CA. To be
