[R] I need help with one question. I already have my clusters, but I don't know how to use the which() function to find the indices. Thanks in advance.

13. Partition the vector into 4 clusters Function needed: Ckmeans.1d.dp (! 14. Reporthe positions (indices) of the numbers in each cluster Function needed: which() For example, if the clustering results are 1 4314111231111212124, then numbers at indices 1 4 678 11 12 13 14 16 18 belong to cluster 1 and so on 13.
