Hello R users,

I'm using SOM() to cluster a gene expression data set

the syntax i used was

dataGrid <- c(somgrid(xdim = 3, ydim = 3, topo = c("rectangular","hexagonal")))
dataClusters <- SOM(dataMatrix, grid = dataGrid)

it seems that this works just fine but the thing i can't figure out is
how to determine where each data point has been clustered.

any suggestions are welcome

thanks in advance

richard mendes
