Hello everyone,
several months ago my Rstudio sessions starts to become unresponsive at several occasions. Unfortunately, I have no reproducible example, as there is no example that triggers the problem reliably.
However, today I encountered the problem four times in a row when I tried to use grepl to select certain columns of a data.frame.
My only hope are the logfiles but I don't understand what they mean. Can anybody help me to understand them and maybe to find the - hopefully easy to fix - problem?
The logfiles from today read
