Dear Rui,
Did you have a look at 'pracma' package? There is a 'kmeanspp' function.

Dear Pascal,
From Wikipedia:
In applied statistics, k-means++ is an algorithm for choosing the
initial values (or "seeds") for the k-means clustering algorithm. It
was proposed in 2007 by David Arthur and Sergei Vassilvitskii, as an
approximation algorithm for the NP-hard k-means problem—a way of
avoiding the sometimes poor clusterings found by the standard k-means
algorithm.

Dear Rui,
What "++" means? There is kmeans in "stats" package.

Dear all.
I am searching for KMeans ++ for R. I cannot find it.
Do you know any package with it?
Best regards,
Rui
