[R] Efficiency of for-loop in R

[jim holtman]

Exactly "what is the problem you are trying to solve"?  Could you
"provide commented, minimal, self-contained, reproducible code"?

A lot depends on what you are trying to do,  There might be other
ways, in R, than a 'for' loop to solve your problems.
