[R] Probabilities for bivariate normal distribution with adapt

["Iwersen, Sönke"]

Dear R-List:

I`m trying to calculate the probabilities for a bivariate normal
distribution while using the mvtnorm-package(dmvnorm) and the
adapt-package for multidimensional integration.

The problem is that I can`t specify the upper bound in the adapt-package
the way I need it because I don`t need a rectangular area. I want to
calculate the probability starting at the origin under the line y=x.  

In MATHEMATICA it`s possible to use 
NIntegrate[pdf, {x, 0, 5}, {y, 0, x}]  with pdf as bivariate
normal distribution but it`s very slow. 

Can anybody help me to do it in R ??

Thanks in advance

Sönke Iwersen
