bare-type-predicates: Bare type predicates

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, n = NULL)
is_bare_atomic(x, n = NULL)
is_bare_vector(x, n = NULL)
is_bare_double(x, n = NULL)
is_bare_complex(x, n = NULL)
is_bare_integer(x, n = NULL)
is_bare_numeric(x, n = NULL)
is_bare_character(x, n = NULL)
is_bare_logical(x, n = NULL)
is_bare_raw(x, n = NULL)
is_bare_string(x, n = NULL)
is_bare_bytes(x, n = NULL)

Arguments

x

Object to be tested.

n

Expected length of a vector.

Details

• The predicates for vectors include the n argument for pattern-matching on the vector length.

• 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.
