check_set_equality: Test if the value sets of two different columns in two different tables are the same

Description

check_set_equality() is a wrapper of check_if_subset(). It tests if one value set is a subset of another and vice versa, i.e., if both sets are the same. If not, it throws an error.

Usage

check_set_equality(t1, c1, t2, c2)

Arguments

t1

Data frame containing the column c1.

c1

Column of t1 that should only contain values that are also in c2 of data frame t2.

t2

Data frame containing the column c2.

c2

Column of t2 that should only contain values that are also in c1 of data frame t1.

Examples

# NOT RUN {
data_1 <- tibble::tibble(a = c(1, 2, 1), b = c(1, 4, 1), c = c(5, 6, 7))
data_2 <- tibble::tibble(a = c(1, 2, 3), b = c(4, 5, 6), c = c(7, 8, 9))
# this is failing:
try(check_set_equality(data_1, a, data_2, a))

data_3 <- tibble::tibble(a = c(2, 1, 2), b = c(4, 5, 6), c = c(7, 8, 9))
# this is passing:
check_set_equality(data_1, a, data_3, a)
# }
