There are limits, and they are quite high -- it is far more likely that
you have an error in your R code.
In this particular case, it is saying that you have more than 50 nested
parse contexts -- that is nested if, [, [[, {, ( calls.
I find it helpful to use a syntax-aware editor (e.g. ESS) as that will
highlight these things for you via indentation patterns.
