Problems with large loops in CentOS

I have run into a problem when do loops with lots of elements in CentOS (I am a new user after using Ubuntu for many years).  I am attaching two scripts, one called
Looping_Centos_minimal_bug_OK.R
which runs fine.  I simply repeat a function call in it 15 times.  However, if I repeat that function call 16 times, as in this one,
Looping_Centos_minimal_bug_breaks.R
I get the error,
Error: unexpected '}' in:
"CorMod
}"

I have a laptop with Ubuntu installed, and everything works fine.  This is just my minimal example.  I have many other scripts with loops, and if they have too many functions in them, they break in CentOS, while they always work in Ubuntu.  I was wondering if anyone else with CentOS or Fedora is having a similar issue, and can reproduce my problem.  Thank you.
