Hello,
Is this expected ?
nchar( c( , NA ) )
[1] 0 2
Should not the second one be NA ?

Hi Romain,
Did you read the help for nchar?
Value:
For ‘nchar’, an integer vector giving the sizes of each element,
currently always ‘2’ for missing values (for ‘NA’).
It may be unexpected behavior, but it's *well-documented* unexpected behavior.

Oh, that must make it ok then.
For a more sensible take:
