[R] memory issue trying to solve too large a problem using hclust

Dear all

I would like to thank all people who have responded (Carlos Ortega,
Aboubakar Maitournam, Ron Wherens, Christian Henning and Andy Liaw).
Some have sent their answers to my mail-address only, so I am never
quite sure if they want me to foreward their answers to r-help or
not. In contrast to S-news, at R most people respond to r-help,
which I find preferable.

I am especially greatful to Andy Liaw ,who mentioned the following
possibility to use correlation in hclust:
  d <- 1-cor(x)^2
  hc <- hclust(as.dist(d))
Sorrowly, I did not have time to try it, but it seems that I would
have to start using more R and less S-Plus, since "as.dist()" does
not exist in S-Plus (maybe it works with dist, I have to try)

Best regards
Christian Stratowa
