| kmeans2 {Mfuzz} | R Documentation |
This function is a wrapper function for
kmeans of the e1071 package. It performs
hard clustering of genes based on their expression values using
the k-means algorithm.
kmeans2(eset,k,iter.max=100)
eset |
object of the class ExpressionSet. |
k |
number of clusters. |
iter.max |
maximal number of iterations. |
An list of clustering components (see kmeans).
