Replace Missing Values in a Character Vector

This function gives a convenient way to replace each missing (NA) value with a given string.

Usage

stri_replace_na(str, replacement = "NA")

Arguments

str

character vector or an object coercible to

replacement

single string

Value

Returns a character vector.

Details

This function is roughly equivalent to str2 <- stri_enc_toutf8(str); str2[is.na(str2)] <- stri_enc_toutf8(replacement); str2. It may be used, e.g., wherever the 'plain R' NA handling is desired, see Examples.
