ERROR: task 1 failed - "Number of clusters 'k' must be in {1,2, .., n-1}; hence n >= 2"`

Hello all,

I was trying to cluster a 642x6 (participants x features) data frame and kept running into an issue with M3C. Here's my code and error.

res <- M3C(just_brain_zscored_complete_df_SIG) M3C method: Monte Carlo simulation objective: entropy clustering algorithm: pam annotation: none running simulations... |=======================================================| 100%Error in { : task 1 failed - "Number of clusters 'k' must be in {1,2, .., n-1}; hence n >= 2"`

Have others run into?

Here's my R sessioninfo()
