Miscellaneous string functions that don't quite fit into the other categories.
string_dup(s, times) string_insert(s, insert, position) string_split(s, split, ...) string_len(s) string_reverse(s) string_unique(s) string_sort(s, descend = FALSE)
| s | A string (character) vector. |
|---|---|
| times | The number of times to duplicate a string. |
| insert | The string to insert. |
| position | The position index to which to insert the string. |
| split | The character by which to split a string vector. |
| ... | Parameters passed to |
| descend | Whether to sort in descending order ( |
string_dup() acts the same as strrep(): it repeats a string n number of times.
string_insert() inserts a string at a specified position.
string_len() acts the same as nchar(): it counts the number of characters per vector element.
string_reverse() reverses the characters in a string.
string_split() acts the same as strsplit(): it splits a string by a specified character.
string_unique() obtains the distinct characters for each element in a vector.
string_sort() arranges the letters in the character vector in order if descend = FALSE (the default) and reverse order if descend = TRUE.
The synonym pattern of these functions are s_*() and *() (insert, len, and reverse). For the former pattern, you can replace with split, unique, and sort, as well.
