check_no_duplicates_in_group: Check for No Duplicates in Group

In vvauditor: Creates Assertion Tests

Check for No Duplicates in Group

Description

This function checks if there is exactly one row per group in the provided dataframe. If there are multiple rows per group, the assertion fails.

Usage

check_no_duplicates_in_group(
  dataframe,
  group_variables = NULL,
  assertion_fail = "stop"
)

Arguments

dataframe	The dataframe to be checked.
group_variables	The group variables as a character vector. The default is NULL.
assertion_fail	How the function reacts to a failure. This can be a "warning", where only a warning is given on the failure, or a "stop", where the function execution is stopped and the message is displayed, or an "AssertCollection", where the failure message is added to an assertion collection.

Examples

# Create a dataframe with some groups having more than one row
dataframe <- data.frame(a = c(1, 1, 2), b = c(2, 2, 3), c = c("x", "x", "y"))
# Check the uniqueness of rows per group
check_no_duplicates_in_group(dataframe)
