compare_datasets {kim}

Compare data sets

Description

Compares whether or not data sets are identical

Usage

compare_datasets(dataset_1 = NULL, dataset_2 = NULL, dataset_list = NULL)

Arguments

dataset_1

a data object (a data frame or a data.table)

dataset_2

another data object (a data frame or a data.table)

dataset_list

list of data objects (data.frame or data.table)

Value

the output will be a data.table showing differences in data sets

Examples

# catch differences in class attributes of the data sets
compare_datasets(
dataset_1 = data.frame(a = 1:2, b = 3:4),
dataset_2 = data.table::data.table(a = 1:2, b = 3:4))
# catch differences in number of columns
compare_datasets(
dataset_1 = data.frame(a = 1:2, b = 3:4, c = 5:6),
dataset_2 = data.frame(a = 1:2, b = 3:4))
# catch differences in number of rows
compare_datasets(
dataset_1 = data.frame(a = 1:2, b = 3:4),
dataset_2 = data.frame(a = 1:10, b = 11:20))
# catch differences in column names
compare_datasets(
dataset_1 = data.frame(A = 1:2, B = 3:4),
dataset_2 = data.frame(a = 1:2, b = 3:4))
# catch differences in values within corresponding columns
compare_datasets(
dataset_1 = data.frame(a = 1:2, b = c(3, 400)),
dataset_2 = data.frame(a = 1:2, b = 3:4))
compare_datasets(
dataset_1 = data.frame(a = 1:2, b = 3:4, c = 5:6),
dataset_2 = data.frame(a = 1:2, b = c(3, 4), c = c(5, 6)))
# check if data sets in a list are identical
compare_datasets(
dataset_list = list(
dt1 = data.frame(a = 1:2, b = 3:4, c = 5:6),
dt2 = data.frame(a = 1:2, b = 3:4),
dt3 = data.frame(a = 1:2, b = 3:4, c = 5:6)))
