You don't want to be down at the C level

Something like this - alternating among continents - happens with AoIR,
the Association for Internet Research. A real effort has been made to
make sure that the conference is in North America no more than every other
year, with alternating slots going to Europe and (once so far..) to
Austra
Some of the bits and pieces in this look like very strong candidates for
breaking off into CRAN packages, if you haven't done so already.
This looks like very nice work - you should be proud! :-)

hi,
You should probably be looking at the functions in the following packages:

graph
dynamicgraph
mathgraph
igraph
Matrix
and a few others ;)

Isn't that supposed to be the wad of files for Windows machines?
there's a different link on the PVM homepage to the source for unices...

Notable that your commandline is trying to use the 10.4u sdk, while ld is
trying to use libdylib "10.5" - aka leopard dynamic linker.
The two probably don't go all that groovily together... :)

I have some problems with DBI package, I want to connect to PostgreSQL
database but I don't know the way to do it.
pg <- dbDriver("PostgreSQL")
... nope. That won't work.
you need the RdbiPgSQL package from Bioconductor. Along with DBI, as I
recall.

Do you have the X11 devel packages installed? You probably do not.

Yes. ;)
Reading the help for dist() and hclust() should make the procedure for
doing this appear fairly str

The functions you'll want to read the documentation to, here, are
"hclust()" and "cutree()". They're fairly straightforward and nicely
documented.

Yes, it is definitely much nicer than the version on www.r-project.org
