are_dbl_ish: Check if an object can be safely coerced to double

In stbl: Stabilize Function Arguments

Check if an object can be safely coerced to double

Description

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

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

Usage

are_dbl_ish(x, ...)

is_dbl_ish(x, ...)

## S3 method for class 'character'
are_dbl_ish(x, ..., coerce_character = TRUE)

## S3 method for class 'factor'
are_dbl_ish(x, ..., coerce_factor = TRUE)

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

Arguments

x	The object to check.
...	Arguments passed to methods.
coerce_character	⁠(length-1 logical)⁠ Should character vectors such as "1" and "2.0" be considered numeric-ish?
coerce_factor	⁠(length-1 logical)⁠ Should factors with values such as "1" and "2.0" be considered numeric-ish? Note that this package uses the character value from the factor, while as.integer() and as.double() use the integer index of the factor.
depth	⁠(length-1 integer)⁠ Current recursion depth. Do not manually set this parameter.

Value

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

Examples

are_dbl_ish(c(1.0, 2.2, 3.14))
is_dbl_ish(c(1.0, 2.2, 3.14))

are_dbl_ish(1:3)
is_dbl_ish(1:3)

are_dbl_ish(c("1.1", "2.2", NA))
is_dbl_ish(c("1.1", "2.2", NA))

are_dbl_ish(c("a", "1.0"))
is_dbl_ish(c("a", "1.0"))

are_dbl_ish(list(1, "2.2", "c"))
is_dbl_ish(list(1, "2.2", "c"))

are_dbl_ish(c(1 + 1i, 1 + 0i, NA))
is_dbl_ish(c(1 + 1i, 1 + 0i, NA))
