Hello everyone,
Again, I apologize for not providing a reproducible example. There was a
small (but important) bug in my R code having nothing to do with system(),
this is now fixed, and everything is working as expected this morning. The

The "whatever information" would be the usual minimal reproducible example.
Since you think your code works at the shell level, make up an example with a
system call to "echo".
Then state what you expect to happen and what happens instead.

around here who came across similar proble
For question 2, my personal favorite is options(error=recover) which
will let you take a look at all levels of the call stack as soon as an
