Pattern matching
String
`str_count()`	Count number of matches
`str_detect()`	Detect the presence/absence of a match
`str_escape()`	Escape regular expression metacharacters
`str_extract()` `str_extract_all()`	Extract the complete match
`str_locate()` `str_locate_all()`	Find location of match
`str_match()` `str_match_all()`	Extract components (capturing groups) from a match
`str_replace()` `str_replace_all()`	Replace matches with new text
`str_remove()` `str_remove_all()`	Remove matched patterns
`str_split()` `str_split_1()` `str_split_fixed()` `str_split_i()`	Split up a string into pieces
`str_starts()` `str_ends()`	Detect the presence/absence of a match at the start/end
`fixed()` `coll()` `regex()` `boundary()`	Control matching behaviour with modifier functions
Vector Unlike other pattern matching functions, these functions operate on the original character vector, not the individual matches.
`str_subset()`	Find matching elements
`str_which()`	Find matching indices
Combining strings
`str_c()`	Join multiple strings into one string
`str_flatten()` `str_flatten_comma()`	Flatten a string
`str_glue()` `str_glue_data()`	Interpolation with glue
Character based
`str_dup()`	Duplicate a string
`str_length()` `str_width()`	Compute the length/width
`str_pad()`	Pad a string to minimum width
`str_sub()` `str_sub<-`() `str_sub_all()`	Get and set substrings using their positions
`str_trim()` `str_squish()`	Remove whitespace
`str_trunc()`	Truncate a string to maximum width
`str_wrap()`	Wrap words into nicely formatted paragraphs
Locale aware
`str_order()` `str_rank()` `str_sort()`	Order, rank, or sort a character vector
`str_equal()`	Determine if two strings are equivalent
`str_to_upper()` `str_to_lower()` `str_to_title()` `str_to_sentence()`	Convert string to upper case, lower case, title case, or sentence case
`str_unique()`	Remove duplicated strings
Other helpers
`invert_match()`	Switch location of matches to location of non-matches
`str_conv()`	Specify the encoding of a string
`str_like()`	Detect a pattern in the same way as `SQL`'s `LIKE` operator
`str_replace_na()`	Turn NA into "NA"
`str_view()`	View strings and matches
`word()`	Extract words from a sentence
Bundled data
`sentences` `fruit` `words`	Sample character vectors for practicing string manipulations
