Analyzing dendrograms
...ty integrating them with the
existing framework--I'm trying to write some resampling routines and
sensitivity tests for tree objects.
Perhaps this question should go to the r-devel list instead....
Yours,

Analyzing dendograms??
I have used heatmap to visualize my microarray data. I have a matrix of
M-values. I do the following.
#The distance between the columns.
sampdist <- dist(t(matrix[,]), method="euclidean")
sclus <- hclust(sampdist, method="average")
#The distance between the rows.
genedist <- dist(matrix[,], method="euclidean")
gclus <- hclust(genedist,

A language technical question.
If I have 100 objekts in a folder and I prefer not to load them manually I
wonder how I do this in R if using a for-loop.
I was thinking initially to do something like this:
infiles <- dir(pattern=".RData")
for(i in length(infiles))
{
load(infiles[i])
paste("kalle", i, sep="") <- saveLoadReference
}
But the line
