[R] NAs are removed

[Ebert,Timothy Aaron]

Hi Neha,
   You used a variable named "fraction" so we took a guess. However, as another pointed out 1/0 does not give NA in R. number/0 returns Inf except 0/0 which returns NaN. So 1/0 <= 1 returns FALSE and 0/0 <= 1 returns NA. A great deal of the behavior of your program hinges on what "fraction" is in your program.

Hi Jim and Ebert

How I am using divide by zero, I did not understand? I am using caret and AUC metric.

If I do, what is the solution?
