Function to automatically coerce integers to 64-bit integers in R?

I am running into an issue where integer calculations within an R-based model I am using are leaving R's 32-bit range. I have tried using the trace() function to manually coerce some of the values of top level functions to 64-bit integers using the bit64 package, however, there are some buried inner calculations in the model that are leaving that range as well, making it impossible to coerce them using surface level functions like trace(). Is there functionality that can automatically coerce R's default 32-bit integers to 64-bit? If not, I will probably just have to revise and recompile the package to get to those inner functions. Thanks!
