Hello Karuna,
Christian answer was great and very detailed.
One more approach you might want to try is using the K-medoids algorithm
instead of the K-means.
That can be used through the pam command (from the cluster package)

Dear R family
I have a following question.
Suppose I have a matrix as follows, for instance:
tau=
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1
1 0 0 0 0
I want to calculate (-m) power of tau, for example, m=893.
When I run tau^2, the outcome is just tau.
Any help would be appreciated.

You can do this using the package numDeriv.
