Dear All, Here is a small example: library(skmeans) library(tm) data("crude") #Examine the first document inspect(crude[[1]]) dtm <- DocumentTermMatrix(crude, control list(removePunctuation = TRUE, removeNumbers = TRUE, stopwords = TRUE)) clus <- skmeans(dtm,3) names(clus) Is there any way I can get the document number of the prototypes ? Also can I get the 3 closest documents to each prototype ? By prototype I mean the cluster centers. I know can compare each row of the DocumentTermMatrix with the prototypes to test for equality and I can manually compute the distance of each Document from a prototypes,but I was wondering if such a tool already exists.
