Check if a number is an integer

Check if a number is an integer

Usage

is_integer(x, non_numbers_as_na = TRUE)

Arguments

x

A vector of one or more values to test.

non_numbers_as_na

The vector is coerced to numeric before checking it is an integer. If this option is set to TRUE (default), non-numeric values in the vector are returned as NA. If it is set to FALSE, non-numeric values are returned as FALSE

Value

A logical vector the same length as X with TRUE for integers, FALSE for non-numeric integers, and either FALSE or NA for non-numeric values.

Examples

x1 <- c(1,2.1,"a")
is_integer(x1, non_numbers_as_na = TRUE)
#> Warning: NAs introduced by coercion
#> [1]  TRUE FALSE    NA
is_integer(x1, non_numbers_as_na = FALSE)
#> Warning: NAs introduced by coercion
#> [1]  TRUE FALSE FALSE
