data.frames joinedsummarise_join_stats.RdCalculates the join count and percentage (by number of rows missing)
of a data.frame that is the results of a join.
summarise_join_stats(data, x, y)
| data | data.frame. This should already by the result of a join. |
|---|---|
| x, y | Either characters or bare names of columns in |
A tibble. One line summary of join metrics,
including the following columns:
x, n_x, n_x_unjoined, x_in_y_pct and their y analogues,
as well as n_joined.
This function is mostly useful after calling dplyr::full_join()
(or a similar function), although it can also be useful for dplyr::left_join()
#' or dplyr::right_join().
The logic for
handling x and y as strings/quos was borrowed from a previous
version of tidyr::gather().
https://github.com/tidyverse/tidyr/blob/master/R/gather.R provides some insight for how to make the function accept either characters or bare names for the column names.
