R help - Mar 2008 - functions

I wrote some functions for multiway CANDECOMP, i.e. for least
squares fitting of

a_{i_1\cdots i_m}\approx\sum_{s=1}^p x^1_{i_1s}x^1_{i_1s}\cdots  
x^m_{i_ms}

with arrays of arbitrary dimension. Reminded me of the good old APL
days. I could not find this in the archives, but if it's already there,
I would appreciate if someone let me know.

Sorry. I mean

a_{i_1i_2\cdots i_m}\approx\sum_{s=1}^p x^1_{i_1s}x^2_{i_2s}\cdots  
x^m_{i_ms}
