String utility

Description

glue() is a shortcut of stringr::str_glue() without trimming.

str_c_coalesce() tries stringr::str_c() first, and falls back to dplyr::coalesce().

rsplit() splits a string from right.

as_chr() converts expr into character vector.

as_code() converts a vector into R code that generates it.

Usage

glue(..., .sep = "", .envir = parent.frame())

glue_data(.x, ..., .sep = "", .envir = parent.frame(), .na = "NA")

str_c_coalesce(..., sep = "", collapse = NULL)

rsplit(string, pattern = "\\s+", n = 42L)

as_chr(...)

as_code(x)

Arguments

`...`	expressions
`.sep`, `sep`	[`character(1)`: ‘""’] Separator used to separate elements.
`.envir`	[`environment`: `parent.frame()`] Environment to evaluate each expression in. Expressions are evaluated from left to right. If `.x` is an environment, the expressions are evaluated in that environment and `.envir` is ignored. If `NULL` is passed, it is equivalent to `emptyenv()`.
`.x`	[`listish`] An environment, list, or data frame used to lookup values.
`.na`	[`character(1)`: ‘NA’] Value to replace `NA` values with. If `NULL` missing values are propagated, that is an `NA` result will cause `NA` output. Otherwise the value is replaced by the value of `.na`.
`collapse`	Optional string used to combine output into single string. Generally better to use `str_flatten()` if you needed this behaviour.
`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 `vignette("regular-expressions")`. Use `regex()` for finer control of the matching behaviour. 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")`.
`n`	Maximum number of pieces to return. Default (Inf) uses all possible split positions. For `str_split()`, this determines the maximum length of each element of the output. For `str_split_fixed()`, this determines the number of columns in the output; if an input is too short, the result will be padded with `""`.
`x`	vector
