# 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.

    ## [1] "a" NA  "b"
    stri_remove_empty(c('a', NA, '', 'b'), TRUE)
    ## [1] "a" "b"
    stri_omit_empty_na(c('a', NA, '', 'b'))
    ## [1] "a" "b"
