is_integerish: Is a vector integer-like?

Description

These predicates check whether R considers a number vector to be integer-like, according to its own tolerance check (which is in fact delegated to the C library). This function is not adapted to data analysis, see the help for base::is.integer() for examples of how to check for whole numbers.

Usage

is_integerish(x, n = NULL, finite = TRUE)
is_bare_integerish(x, n = NULL)
is_scalar_integerish(x)

Arguments

x

Object to be tested.

n

Expected length of a vector.

finite

Whether values must be finite. Examples of non-finite values are Inf, -Inf and NaN.

See Also

is_bare_numeric() for testing whether an object is a base numeric type (a bare double or integer vector).

Examples

# NOT RUN {
is_integerish(10L)
is_integerish(10.0)
is_integerish(10.0, n = 2)
is_integerish(10.000001)
is_integerish(TRUE)
# }
