Replace Missing Values in a Character Vector
This function gives a convenient way to replace each missing (NA)
value with a given string.
stri_replace_na(str, replacement = "NA")
str |
character vector or an object coercible to |
replacement |
single string |
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.
