[R] integrate()

[Robin Hankin]

Hi

I found the following unexpected:

 > integrate(function(x){0*x+1+1i},0,1)
1 with absolute error < 1.1e-14
 >

One can write a little wrapper, but it's messy.  Would it be hard to
accommodate such functions?

The manpage for integrate() does not mention imaginary numbers.
