hc - hclustdist_mat_matError in if isnan n 65536L stopsize cannot be NA nor exceed 65536 missing value where TRUEFALSE needed

This error occurs because the number of objects in the distance matrix is too large for the hclust function to handle. The maximum number of objects that can be handled by hclust is 65536. To resolve this issue, you can either reduce the number of objects in the distance matrix or use a different clustering algorithm that can handle larger datasets.
