Seems unlikely that RStudio has much to do with this matter. I'm reasonably sure that you would need to compile R to link to OpenBLAS but I think LAPACK is the default math package (although you can use an "external" version).

Search for:
A.3.1.3 Goto and OpenBLAS   # in the 'R Installation and Administration' manual

I thought R's binary wasn't set up to run under Cygwin?

And I didn't change my mind after reading Section:
C.8 Cygwin

I think follow-up question on this matter would be more appropriate on R-devel, but they really do expect you to RTM.
