get many text messages after a 500-iteration run of decipherMutationalProcesses

[AGordonRobertson]

In RStudio, using CRAN mutSignatures v2.0.1 on R 4.0.2, I'm getting many text messages when a 500-iteration decipherMutationalProcesses job finishes. For example, is the following expected?

My sense is that when I get these messages, I do not get a silhouette plot that I can see in RStudio's Plots panel. Perhaps I should not be running a parallel (foreach) job in RStudio, but should run it in a terminal?
