Integer generators

A set of generators for integer vectors.

Usage

integer_(len = c(1L, 10L), any_na = FALSE, big_int = FALSE)

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

integer_left_bounded(left, len = c(1L, 10L), any_na = FALSE, big_int = FALSE)

integer_right_bounded(right, len = c(1L, 10L), any_na = FALSE, big_int = FALSE)

integer_positive(len = c(1L, 10L), any_na = FALSE, big_int = FALSE)

integer_negative(len = c(1L, 10L), any_na = FALSE, big_int = 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_int

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

left

The minimum possible value for generated numbers, inclusive.

right

The maximum possible value for generated numbers, inclusive.

Value

A quickcheck_generator object.

Examples

integer_() %>% show_example()
#> [1] -8818 -9394   428  4806 -1093 -3786  4696   238     0
integer_(big_int = TRUE) %>% show_example()
#> [1]   736816680 -1730886292           0  -174129295
integer_bounded(left = -5L, right = 5L) %>% show_example()
#> [1]  1  3 -3
integer_(len = 10L, any_na = TRUE) %>% show_example()
#>  [1]    NA   691  9262     0    NA    NA -5561 -5609  1255 -3302
