The gamma function and infinity

I have to calculate some formula like: gamma(x)/(gamma(x+y) and I observed that for relatively big values of x, R returns infinity and so cannot compute the formula. Is it possible to force R to give the real value of gamma(x) instead of Inf ?
No, it is overflowing the floating point representation. How about using lgamma? That's basically what it is for.
