[R] S4, polymorphism, and parallelization

[R] Normal cdf modified function

I wonder if an R package would have a function that calculates the following. Let Y be a normal multivariate function. For example, let Y have 4 dimensions. I want to calculate P(Y1 Z1, Y2 Z2, Y3 Z3, Y4 Z4). There are R functions to do the calculation if all the inequalities are of the type
