Error Detecting clusters

[massihonda]

Hello, I am trying to use codeface for my research but I encounter a problem when it finishes the blame analysis. When it starts Revision range after the blame analysis it says:
2020-04-15 18:16:30 [codeface.util] Process-2 INFO: -> Revision range 60/61 (bbb13e..8da2c5): Commit analysis done.
2020-04-15 18:16:30 [codeface.util] Process-2 INFO: -> Revision range 1/61 (e83c51..ad8c80): Detecting clusters...
Pass 1/2: 33% |############################# | ETA: 0:00:13: No such file or directory
2020-04-15 18:16:31 [codeface.util] Process-2 ERROR: Command '/vagrant/codeface/R/cluster/persons.r --loglevel info -c /vagrant/codeface.conf -p /tmp/gitESh228 /home/vagrant/res-Git/git/tag/001--e83c51-ad8c80 170' failed with exit code 127.

Is there a reason for that I am missing?

Best,
Massimo
