Hello,

Though I think you should compute that integral symbolically by hand and then define a function with the result, maybe package pracma can do what you want.
[functions dblquad(9 and quad2d()]


Hope this helps,

Dear R-users,

I'm wondering how to calculate this double integral in R:

int_a^b  int_c^y g(x, y) dx dy

where g(x,y) = exp(- alpha (y - x)) * b

Thanks for answering!

Cheers,

Alui
