I want to call R from Perl to generate plots to be displayed on a

That's exactly what a batch file should do. There is no GUI to run.

Not sure if this a bioconductor question or general R mailing list

When plotting dendrograms created by hclust you can identify clusters

each cluster.
That´s what I needed. Thanks!

There is no threshold for fdr. The adjusted p-values give the expected
proportion of false positives for all comparisons with similar p-values

positives.
For any matrix, the following definitions hold:
row rank: number of linearly independent rows
column rank: number of linearly independent columns
There is a theorem stating that these 2 numbers must be the same

Where did you find that function? In rw1080 on windows XP I get:
Some earlier versions of the maps package (which was then available for

I believe in R you need
