R: View HTML rendering of regular expression match.

str_view {stringr} | R Documentation

## View HTML rendering of regular expression match.

### Description

`str_view` shows the first match; `str_view_all` shows all the matches.

### Usage

    str_view(string, pattern, match = NA)

    str_view_all(string, pattern, match = NA)

### Arguments

`string` | Input vector. Either a character vector, or something coercible to one.
`pattern` | Pattern to look for. The default interpretation is a regular expression, as described in stringi::stringi-search-regex. Control options with `regex()`. Match a fixed string (i.e. by comparing only bytes), using `fixed()`. This is fast, but approximate. Generally, for matching human text, you'll want `coll()` which respects character matching rules for the specified locale. Match character, word, line and sentence boundaries with `boundary()`. An empty pattern, "", is equivalent to `boundary("character")`.
`match` | If `TRUE`, shows only strings that match the pattern. If `FALSE`, shows only the strings that don't match the pattern. Otherwise (the default, `NA`) displays both matches and non-matches.

### Examples

    str_view(c("abc", "def", "fgh"), "[aeiou]")
    str_view(c("abc", "def", "fgh"), "^")
    str_view(c("abc", "def", "fgh"), "..")

    # Show all matches with str_view_all
    str_view_all(c("abc", "def", "fgh"), "d|e")

    # Use match to control what is shown
    str_view(c("abc", "def", "fgh"), "d|e")
    str_view(c("abc", "def", "fgh"), "d|e", match = TRUE)
    str_view(c("abc", "def", "fgh"), "d|e", match = FALSE)
