speed of the cluster.stats function
...ot the library fpc that you built for R, specially the
cluster.stats function. In that function, the calculation of G2 index
(Goodman & Kruskal) could be really slow as you warned in the help page
for that function. That speed problem is due to the double loop for(i in
1:nwithin) for(j in 1:nbetween).
I came up with a solution (probably not the best, but ....) that is
really faster than your's (with all due respect). (You can see the speed
calculation above). What i did was just vectorizing the second loop. See
the code in the patch above.
Could be a good thing for the next fpc releas...
