R Documentation

Replaces string or NA in a character vector with either NA or another string.

This is to augment stri_replace_all_fixed(), which does not allow NA as a pattern.

str_or_na_replace(x, pattern, replacement, fold = FALSE)

`x`	character vector
`pattern`	string pattern to search for may be empty string or NA. Comparison is done with "==". Case can be ignored.
`replacement`	string to replace entire entity that has pattern.
`fold`	logical value where if TRUE the vector `x` and `pattern` are converted to lower case.
