data_frame_of {quickcheck}

Data frame generator with randomized columns

Description

Data frame generator with randomized columns

Usage

data_frame_of(..., rows = c(1L, 10L), cols = c(1L, 10L))

Arguments

...

A set of unnamed generators. The generated data frames will be built with random combinations of these generators.

rows

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

cols

Number of columns of the generated data frame. If cols is a single number all data frames will have this number of columns. If cols is a numeric vector of length 2 it will produce data frames with columns between a minimum and maximum, inclusive. For example cols = c(1L, 10L) would produce data frames with columns between 1 and 10. To produce empty tibbles set cols = 0L or a range like cols = c(0L, 10L).

Value

A quickcheck_generator object.

Examples

data_frame_of(logical_(), date_()) %>% show_example()
data_frame_of(any_atomic(), rows = 10L, cols = 5L) %>% show_example()
