Assert minimum coverage of values

Checks that the fraction of non-NA values meets a threshold. Useful after joins to verify expected coverage.

Usage

lock_coverage(.data, threshold, ..., .strict = FALSE)

Arguments

.data

A data frame.

threshold

Minimum fraction of non-NA values (0 to 1).

...

Column names (unquoted) to check. If empty, checks all columns.

.strict

If TRUE, error on failure. If FALSE (default), warn.

Value

Invisibly returns .data (for piping).

Examples

df <- data.frame(id = 1:10, x = c(1:8, NA, NA))
lock_coverage(df, 0.8, x)
lock_coverage(df, 0.9, x)  # warns (only 80% coverage)
