[R] How to do clustering

2007-06-07 Thread ssls sddd
Dear List,

I have another question to bother you about how to do clustering.
My data consists of 49 columns (49 variables) and 238804 rows.
I would like to do hierarchical clustering (unsupervised clustering
and PCA). So far I tried pvclust (www.is.titech.ac.jp/~shimo/prog/*pvclust*
/)
but I always had the problem like for R like cannot allocate the memory.

I am curious about what else packages can perform the clustering analysis
while memory efficient.

Meanwhile, is there any way that I can extract the features of each cluster.

In other words, I would like to identify which are responsible for
classifying these
variables (samples).

Thanks a lot!

Sincerely,

Alex

sorry, I hit send before finishing my thoughts...

and as for clustering microarray data, you might want to consider the  
bioconductor mailing list...

Hi Alex,

just in case you're trying to get genotypes from the Affymetrix 500K  
set, you might want to check the oligo package available on  
BioConductor.

best,
