Check if an object can be safely coerced to character

are_chr_ish() is a vectorized predicate function that checks whether each element of its input can be safely coerced to a character vector.

is_chr_ish() is a scalar predicate function that checks if all elements of its input can be safely coerced to a character vector.

Usage

are_chr_ish(x, ...)

is_chr_ish(x, ...)

# Default S3 method
are_chr_ish(x, ..., depth = 1)

Arguments

x

The object to check.

...

Arguments passed to methods.

depth

(length-1 integer) Current recursion depth. Do not manually set this parameter.

Value

are_chr_ish() returns a logical vector with the same length as the input. is_chr_ish() returns a length-1 logical (TRUE or FALSE) for the entire vector.

Examples

are_chr_ish(letters)
#>  [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE
#> [16] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE
is_chr_ish(letters)
#> [1] TRUE

are_chr_ish(1:10)
#>  [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE
is_chr_ish(1:10)
#> [1] TRUE

are_chr_ish(list("a", 1, TRUE))
#> [1] TRUE TRUE TRUE
is_chr_ish(list("a", 1, TRUE))
#> [1] TRUE

are_chr_ish(list("a", 1, list(1, 2)))
#> [1]  TRUE  TRUE FALSE
is_chr_ish(list("a", 1, list(1, 2)))
#> [1] FALSE
