[R] Factors and NaN

[Dinesh Chowdhary]

R-3.1.2

> x <- factor(c("yes", "yes", "no", NA, "yes", "no", NaN))
> x
[1] yes  yes  no   <NA> yes  no   NaN
Levels: NaN no yes
> is.nan(x)
[1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE

>From the above snippet can you notice that the "NaN" value is not logically
identified in a vector? Can anyone elaborate on this?
