[R] recursion depth limitations

[Suzen, Mehmet]

Hello List,

I am aware that one can set with recursion depth 'options(expressions
= #)', but it has 500K limit. Why do we have a 500K limit on this?
While some algorithms are only "solvable"  feasibility with recursion
and 500K sounds not too much i.e. graph algorithms
for example dependency trees with large nodes easily reach to that number.

Best,
