bare-type-predicates: Bare type predicates

In imanuelcostigan/predrcats: Predicate Functions with Sane Interfaces and Behaviours

Description

These predicates check for a given type but only return TRUE for bare R objects. Bare objects have no class attributes. For example, a data frame is a list, but not a bare list.

Usage

is_bare_list(x)

is_bare_atomic(x)

is_bare_vector(x)

is_bare_double(x)

is_bare_integer(x)

is_bare_numeric(x)

is_bare_character(x)

is_bare_logical(x)

Arguments

x	object to be tested.

Details

• Like is_atomic() and unlike base R is.atomic(), is_bare_atomic() does not return TRUE for NULL.

• Unlike base R is.numeric(), is_bare_double() only returns TRUE for floating point numbers.

Value

TRUE or FALSE
