Replace all pattern matches in a string

Replaces every occurrence of pattern in string with replacement. Supports both regular expressions and literal string matching via fixed().

Usage

str_replace_all(string, pattern, replacement)

Arguments

string

A character vector.

pattern

A regular expression string, or a literal string wrapped in fixed(), or a named character vector where names are regex patterns and values are replacements (applied sequentially).

replacement

A character string to replace each match with. Use "" to delete matches.

Value

A character vector the same length as string.

Examples

# Regex replacement
str_replace_all("hello world", "o", "0")
#> [1] "hell0 w0rld"

# Fixed (literal) replacement
str_replace_all("a.b.c", fixed("."), "-")
#> [1] "a-b-c"

# Remove all spaces
str_replace_all("remove all spaces", fixed(" "), "")
#> [1] "removeallspaces"

# Named vector: multiple replacements applied in order
str_replace_all("aabbcc", c("a" = "X", "b" = "Y"))
#> [1] "XXYYcc"
