The uniform distribution with infinite range gives each possible

That's also true of a finite range uniform distribution.
In the standard real numbers, that probability is ZERO.
So is that.
In fact, the probability of getting a number in *any* prespecified
finite range is the same, ZERO.
That's not true for the finite range version, only the improper one.

One such finite range is the numbers that can be represented in floating-point.
So you are with certainty not going to draw a representable number.
A complete answer to your question is thus
ifelse(runif(N) < 0.5, 1, -1)/0 >
Why do you think you need this?

Hi,
I want to draw a set of random number from Uniform distribution where
Support is the entire Real line.
runif(4, min = -Inf, max = Inf)
However it produces all NAN
Could you please help with the right approach?
