string, something that I find strange. At best NA is the equivalent of an empty string. In this sense, if you Hmisc::describe() the vector you get, as I would expect, that in the context of character vectors NA and '' values are considered together:
By the way, same question holds for nchar(): Should NA values be reported as 2-char strings, or as 0-char empty/missing values?
x <- c(letters, NA, '') nchar(x)
