I would appreciate some help with clustering
Is this homework? If so, you should discuss it with the instructor, not us. Regardless, the methods you suggested are a reasonable place to start, and you perhaps should have done so first before asking here. You may well have gotten the results you needed without the delay of waiting for an answer on the list. Sarab

I have a binary vector whose length is known.
Such a vector contains an unspecified number of 1s.
My goal is
1. to generate as many clusters as the number of 1s
2. to place the 1 as much as possible at the center of its own cluster
Example. Say I have the following binary vector:
v <- c(0,0,1,0,0,0,0,1,0,1,0,0)
Then I have to get 3 clusters.
I can generate a matrix containing the distance of each element from each one of the
clusters center (the 1s):
1st_1 2nd_1 3rd_1
---|-----------------------------------
0 | 2 7 9
0 | 1 6 8
1 | 0 5 7
0 | 1 4 6
0 | 2 3 5
0 | 3 2 4
0 | 4 1 3
1 | 5 0 2
0 | 6 1 1
1 | 7 2 0
0 | 8 3 1
0 | 9 4 2
Should I input such matrix to R function "dist" and then use for instance PAM or KMEAN
to get the expected 3 clusters ?
I would greatly appreciate some help.
Thank you so much.
