Ermmm... from ?integrate
"Description:
Adaptive quadrature of functions of one variable over a finite or
infinite interval."
R maps infinite intervals to a finite interval before numerical integration,
provided that you tell it that the limits are infinite.
Using integrate() over multivariate intervals will get very slow, though; I
wouldn't do that...

No, R does numerical (not symbolical) calculations, hence it can never
perform integration (not even univariate) with infinite limits.
