One more thing - for large data sets, the packages flashClust and
fastcluster provide much faster hierarchical clustering that (at least
for flashClust which I'm the maintainer of) give the exact same
results. Simply insert a
library(flashClust)
before you call the function and your code will run
Hi Paul,
I assume you are using the argument cutoff to specify the p-value
below which nodes are considered connected and above which they are
not connected.
I would use single linkage hierarchical clustering. If you have two
groups of nodes and any two nodes between the groups are connected
(i.e
Sorry bad example. My data is undirected. It's a correlation matrix so probably
better to look at something like:
foomat<-cor(matrix(rnorm(100), ncol=10))
foomat
mine are pvalues from the correlation but same idea.

Dear all,
I'm having some problems getting my recursive function to work. At first I
though that maybe my data was too big and I increase option(expressions=5).
Then I thought that I would try it on some smaller data. Still not working. :(
I would have thought there should be a function for
