[Rd] NAs in unsplit factor

[Jeff Enos]

R-devel,

Below is a simple example calling split and unsplit on a numeric
vector of length 2 where 'f' is c(1,NA).

> unsplit(split(c(1,2), c(1,NA)), c(1,NA))
[1] 1 0

I noticed that the call to vector in unsplit gives us 0 as the 2nd
element of the result.

Is this the intended result, as opposed to NA?

Thanks for your help,

Jeff
