Returns the rows that are present on only one side of a comparison
("base_only" or "comp_only"), with their original data columns.
Mirrors the "Observations in PROC COMPARE.
Usage
ks_unmatched_rows(x, side = c("both", "base_only", "comp_only"))Value
A tibble with columns side, key_id, key_label,
base_row, comp_row, followed by the data columns from the
side that holds each row (base_row is NA for comp_only
rows and vice versa, making it trivial to look an observation
up in the original base / comp frame).
Empty (zero-row) tibble when there are no unmatched rows.
Details
The result is precomputed at ks_compare() time and capped by the
max_unmatched_rows argument (default 100). When the cap kicks
in, the truncated attribute is set and the full counts are
recorded on n_total.
Examples
a <- data.frame(id = 1:3, x = c(1, 2, 3))
b <- data.frame(id = 2:4, x = c(2, 3, 4))
cmp <- ks_compare(a, b, by = "id")
#> ⚠ a vs b — no value diffs; 2 unmatched row(s)
ks_unmatched_rows(cmp)
