[R] elseif syntax

[Christos Hatzis]

Another option in R is to use the vectorized version 'ifelse', which has an
advantage if x is a vector:

> x <- -1:4
> x
[1] -1  0  1  2  3  4
> ifelse(x == 1, 'same', ifelse(x > 1, 'bigger', 'smaller'))
[1] "smaller" "smaller" "same"    "bigger"  "bigger"  "bigger"
