Assign class to data frame after clustering

Question

I used k-means cluster algorithm on a data-frame df1 and the result is shown in the picture below.

library(ade4)
df1 <- data.frame(x=runif(100), y=runif(100))
plot(df1)
km <- kmeans(df1, centers=3)
kmeansRes<-factor(km$cluster)
s.class(df1,fac=kmeansRes, add.plot=TRUE, col=rainbow(nlevels(kmeansRes)))

enter image description here Is there a possibility to add to the data frame information from which cluster does the observation come from?

`df1$cluster <- km$cluster` should work – hrbrmstr May 15 '15 at 13:07 — hrbrmstr, May 15 '15 at 13:07

You already have the information you want:

kmeansRes<-factor(km$cluster)

just add it to your data frame as additional column.

df1$cluster <- km$cluster
