Do you mean with millions of different patterns (motifs)? If not, the
R-level regular expression functions are vectorized, and so the looping
will already happen for you in C.
Also, have you confirmed that the R evaluation overhead will actually
dominate the pattern matching here if you just do it in R? That very well
may be, but it's not obvious to me that it would depending on details about
what you're doing that I'm not privy to.
