Due to popular request (like three times in the last five years ;-D), I 
have added a 'distmeth' argument to both clusterComp() and benhur(). 
Valid choices are "euclidean" (default) and "pearson". If you choose 
"pearson", then the distance measure will be 1-cor(<yourdatahere>).

This is in the devel branch, version 1.25.1 and will be propagated 
through the build system in the next couple of days.

You don't technically need the devel version of R to use it, just 
download the correct version for your OS and install.

Best,

Jim
