[R] Beyond double-precision?

I need to perform some calculations with some extremely small numbers (i.e. likelihood values on the order of 1.0E-16,000). Even when using the double() function, R is rounding these values to zero. Is there any way to get R to deal with such small numbers? For example, I would like to be able
