[BioC] Interrupting an R command

[Kasper Daniel Hansen]

There is no other way.

How effective C-c is depends a lot on the code you are running.  In C
code for example the author has to place a command like
  checkUserInterrupt()
once in a while.  Some packages don't do this, making them impossible
to interrupt.  Some packages do this inside a for loop, only checking
for example every 1000 iterations.  In that case you have to wait
until the code reaches the interrupt check, which may take forever if
the system is starting to swap a lot.

I don't know which category randomForest belongs to.
