[R] Mediation analysis takes up all RAM, then all swap, and then RStudio/terminal suddenly closes

[Phillips Rogfield]

Hello Bert,

thank you for your kinds answer.

No I didn't contact the maintainer of the package first, that's my fault :)

I have come to the conclusion that the problem is that I don't have 
enough resources on my PC (RAM) for the task at hand.

I have tried to run it on a remote VM with more RAM and seems to work.

Best regards
