Please consider the following two R statements:
A = runif(20, min=-1,max=1)
ifelse( A < 0, sqrt(-A), A )
The second statement produces the following error message:
rt(-A) : NaNs produced
I understand that you cannot take the square root of a negative number
but I thought the condition A < 0
would take care of that issue. It appears not to be.
What am I missing?
Thanks,
Bob
