Yes, based on my informal benchmarking, lm is the main "bottleneck", the rest
of the code consists mostly of vector manipulations and control structures.
I am not familiar with lm.fit, I'll definitely look it up. I hope it's similar
enough to make it easy to substitute one for the other.
Thanks for the suggestion, much appreciated. (My runs now take sometimes
several hours, it would be great to cut that time down by any amount :-)
