I'm trying to run a bunch of tasks in parallel using 'Future' package and
for some reason, it's not able to find the data frames that I want it to
find. I've created the below sample program to show what I'm doing. Should
I be exporting the Global data to each child process? I am not doing that
currently because I read somewhere that it's automatically done when using
the multisession plan. Any idea what I'm doing wrong?
