printing hclust with k clusters
howdy R friends, I've searched CRAN but to no avail... I'm trying to use mva's hclust and print out for say 10 clusters in batch. How do I do this?

cant find "get"?
...wdy gurus, I was wondering if someone could help me with what looks like a simple problem. I found this great function called "get" which allows me to work out my object name at run time.

R on os390
G'day R friends, I didn't get any replies on the main list so I thought I'd try with the experts. I was wondering if anyone's ported R to os390. If so, are the vsize and nsize limits the same as other platforms?

tapply, sorting and the heap

Factor Analysis
Thanks to Brian Ripley for the time and effort put into developing the factanal package for R. I have found it very useful. However, in trying to replicate some results from previous research, I have run into the need for a couple of extensions and was wondering if they might find their way into future implementations. 1. Though maximum likelihood estimates might be more rigorous and
