Dear all,
i have a little trouble with cutting an understanding the handling of

is that the dendrogram shows lots of pretty small clusters and only
some larger ones.

I would like to maximize the following function fqp with linear constraits

This depends on the editor you use for writing R code rather than on R.

Hello,
How do I sample observations with replacement from a normal distribution

Hi John,
I've used Emacs + ESS under Fedora since Core 1 and the easiest way I
found to install it was to follow the instructions on the ESS web-page.
This had the downside of actively having to be involved with updating to
later versions of ESS, so it was a nice surprise to find that ESS is

Dear Brian, thank you for helping. You are right, I was not aware of these two
different meaning of bg. I will have a closer look to those help pages (whereas
I've consulted
