stri_remove_empty

Remove All Empty Strings from a Character Vector

Description

stri_remove_empty (alias stri_omit_empty) removes all empty strings from a character vector, and, if na_empty is TRUE, also gets rid of all missing values.

stri_remove_empty_na (alias stri_omit_empty_na) removes both empty strings and missing values.

stri_remove_na (alias stri_omit_na) returns a version of x with missing values removed.

Usage

stri_remove_empty(x, na_empty = FALSE)

stri_omit_empty(x, na_empty = FALSE)

stri_remove_empty_na(x)

stri_omit_empty_na(x)

stri_remove_na(x)

stri_omit_na(x)

Arguments

`x`	a character vector
`na_empty`	should missing values be treated as empty strings?

Value

Returns a character vector.

Examples

stri_remove_empty(stri_na2empty(c('a', NA, '', 'b')))
stri_remove_empty(c('a', NA, '', 'b'))
stri_remove_empty(c('a', NA, '', 'b'), TRUE)
