Double generators

Source: R/double.R
double_.Rd

A set of generators for double vectors.

Usage

double_(
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

double_bounded(
  left,
  right,
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE
)

double_left_bounded(
  left,
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

double_right_bounded(
  right,
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

double_positive(
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

double_negative(
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

double_fractional(
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

double_whole(
  len = c(1L, 10L),
  any_na = FALSE,
  any_nan = FALSE,
  any_inf = FALSE,
  big_dbl = FALSE
)

Arguments

len

Length of the generated vectors. If len is a single number all vectors will have this length. If len is a numeric vector of length 2 it will produce vectors with lengths between a minimum and maximum, inclusive. For example len = c(1L, 10L) would produce vectors with lengths between 1 and 10. To produce empty vectors set len = 0L or a range like len = c(0L, 10L).

any_na

Whether NA values should be allowed.

any_nan

Whether NaN values should be allowed.

any_inf

Whether Inf/-Inf values should be allowed.

big_dbl

Should doubles near the maximum size be included? This may cause problems because if the result of a computation results in a double larger than the maximum it will return Inf.

left

The minimum possible value for generated numbers, inclusive.

right

The maximum possible value for generated numbers, inclusive.

Value

A quickcheck_generator object.
