Omit missing values/rows

Returns data object with NA values (if atomic vector), all NA elements (if list), or all NA rows (if data frame or matrix) omitted

na_omit(x)

Arguments

x	Data object

Value

Data with NA values (if atomic vector), all NA elements (if list), or all NA rows (if data frame or matrix) omitted.

Examples

## generate data
df <- data.frame(
  a = I(list(c(1, 2), c(NA_integer_, NA_integer_), c(1, 2))),
  b = c("a", NA_character_, "c"),
  c = c(1.1243, NA_real_, -1.234134)
)

## data frame
