Paste Omitting NA Values

Pastes elements together while omitting NA values, returning NA only if all values are NA.

Usage

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

Arguments

...

one or more R objects, to be converted to character vectors.

sep

a character string to separate the terms. Not NA_character_.

collapse

an optional character string to separate the results. Not NA_character_. When collapse is a string, the result is always a string (character of length 1).

Examples

paste_na_rm(
  c(letters[1:2], NA, NA),
  c(1, NA, NA, 4),
  sep = ", "
)
#> [1] "a, 1" "b"    NA     "4"   

paste_na_rm(
  c(letters[1:2], NA, NA),
  c(1, NA, NA, 4),
  sep = ", ",
  collapse = "; "
)
#> [1] "a, 1; b; 4"
