Robin,
You could try
b <- complex(real=1, im=Inf)

Asunto: [R] Inf +1i vs 1+Inf*1i
Hi
If I have
a <- Inf + 1i
then
Re(a) is Inf, and Im(a) is 1, as expected.
But if
b <- 1 + Inf * 1i,
then
Im(b) = Inf , as expected, but Re(b) = NaN, which I didn't expect.
Why this asymmetry? How to define an object with Re(b)=1, Im(b)=Inf?
