[datatable-help] Bug filled [#4878]

[Arunkumar Srinivasan]

Statquant, 

I don't think this is a bug because the default NA is indeed NA_logical_

IF you do:

x <- rep(NA, 10)
class(x) # [1] logical

You should just do:

x <- rep(NA_integer_, 10)
class(x) # [1] integer

>From ?NA (first paragraph)
NA is a logical constant of length 1 which contains a missing value indicator. NA can be coerced to any other vector type except raw. There are also constants NA_integer_, NA_real_, NA_complex_ and NA_character_ of the other atomic vector types which support missing values: all of these are reserved (http://127.0.0.1:42400/help/library/base/help/reserved) words in the R language.
