about hcluster
Hi all:
As to hcluster,how can I control the cluster is performed according to rows(genes for instance) or columns(samples for instance)?
I can't find the parameters for it.
Thanks a lot!
My best!

distance matrix and hclustering
...)
by using "as.matrix", i converted by data into a matrix. Now, I want to create a distance matrix. My data as shown above contains 364 rows and 4 columns. I have to create distance matrix based on the values of 2nd column.
secondly, based on this distance matrix i would like to do "hclustering", to see which of the rivers have similar discharge patterns. more precisely, i need to see river(a,b,c,d) splitted in clusters with river having similar discharge patterns in one cluster.
thnx in advanceeliza botto

how can I import a number of datsets in a folder in my working directory to a list in R
Hi,
Suppose, if I create 15 files in my working directory.
set.seed(48)
lapply(1:15,function(i) {m1 <- matrix(sample(1:20,1686*2,replace=TRUE),nrow=1686,ncol=2); write.table(m1,paste0("file_",i,".txt"),row.names=FALSE,quote=FALSE)})
?D <-dir()
D1 <- D[order(as.numeric(gsub("\\D+","",D)))]

?res <- t(sapply(D1,function(x) {x1<-

Dear useRs,
i am using NbClust to determine appropriate number of cluster for hclustering. i am consistently getting the following error
Error in if (is.na(n) || n > 65536L) stop("size cannot be NA nor exceed 65536") :
missing value where TRUE/FALSE needed
Does any one know where i am wrong??
