Mark a pattern as a fixed string

Flags a pattern to be interpreted as a literal string rather than a regular expression. Pass the result to str_replace, str_replace_all, str_count, or str_split_fixed wherever you want exact character matching instead of regex matching.

Usage

fixed(pattern)

Arguments

pattern

A character string to match literally.

Value

The same character string with class "fixed_pattern".

Examples

# Without fixed(), "." matches any character (regex)
str_replace_all("a.b.c", ".", "-")
#> [1] "-----"

# With fixed(), "." matches only a literal dot
str_replace_all("a.b.c", fixed("."), "-")
#> [1] "a-b-c"
