mlampros / ClusterR

Not sure if a bug or intended behavior, but when using ClusterR::Optimal_Clusters_GMM I get a warning the number of columns of the data should be larger than 'max_clusters' triggered by:

ClusterR/R/clustering_functions.R

Line 248 in d9ff519

    
           if (ncol(data) < max(max_clusters) && verbose) { warning("the number of columns of the data should be larger than the maximum value of 'max_clusters'", call. = F); cat(" ", '\n') }

However, from the examples I would assume we are trying to cluster observations rather than parameters? Hence shouldn't the number of rows be used to trigger this warning?

@FMKerckhof yes that's true, based on the Armadillo documentation

The k parameter indicates the number of centroids; the number of samples in the data matrix should be much larger than k

give me a few days and I'll fix both the code and the documentation of the package

I just updated the code, now it should show the warning if the number of clusters are bigger than the number of observations.
I'll close the issue for now, feel free to re-open it in case that the code does not work as expected.
