Hi, Lynette,
A few pointers:
1. Not an R question.
2. Not an ESS question.
3. No reproducible example.
4. (x >= 1/4) is comparing a pointer. Surely, this is not what you
intended to do. Plus, if you're using void* then this is not even a C
function called by R. And I'm not familiar with Rdqags.

I think Paul's suggestion works if you use:
