[R-pkg-devel] R_CStackLimit and OpenMP for CRAN Packages

[Jonathan Lisic]

After about a three hour slog through my code I was able to track down and eliminate any non-essential function calls.  The function call removal significantly decreased the stack size, removing the requirement for R_CStackLimit bound to be changed.

Thanks,

Jonathan Lisic
