Numeric generators

A set of generators for numeric vectors. Numeric vectors can be either integer or double vectors.

Usage

numeric_(len = c(1L, 10L), any_na = FALSE, big_num = FALSE)

numeric_bounded(left, right, len = c(1L, 10L), any_na = FALSE)

numeric_left_bounded(left, len = c(1L, 10L), any_na = FALSE, big_num = FALSE)

numeric_right_bounded(right, len = c(1L, 10L), any_na = FALSE, big_num = FALSE)

numeric_positive(len = c(1L, 10L), any_na = FALSE, big_num = FALSE)

numeric_negative(len = c(1L, 10L), any_na = FALSE, big_num = 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.

big_num

Should integers or doubles near the maximum size be included? This may cause problems because if the result of a computation results in a number larger than the maximum an integer will be silently coerced to a double and a double 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.

Examples

numeric_() %>% show_example()
#> [1]  1500  3875 -8377 -5401 -1367
numeric_(big_num = TRUE) %>% show_example()
#> [1]     572149  672724392 1432248207 1015662317  162297194
numeric_bounded(left = -5L, right = 5L) %>% show_example()
