Print a plain-text detail report for one safe_merge result

Print static knitr::kable() tables (no plots, no htmlwidgets) for the key diagnostic sections of a safe_merge() result: the validation checks, unmatched key combinations on each side, overlapping non-key variables, and suspicious duplicate-variable conflicts. Sections with nothing to show are skipped entirely.

Usage

merge_detail(m, TopN = 10)

Arguments

m

A list returned by safe_merge() (must contain a validation element from ValidateMerge() and a log tibble).

TopN

Integer. Maximum number of rows shown for the left-only and right-only unmatched-key previews. Default is 10.

Value

m, invisibly. Called for its printed output.

Details

In R Markdown or Quarto, use a chunk with results = "asis" so the kable markdown renders as tables.

Examples

baseline <- data.frame(id = 1:4, age = c(50, 61, 45, 58))
labs <- data.frame(id = c(1, 2, 4), glucose = c(90, 110, 100))
m <- safe_merge(baseline, labs, by = "id", name = "Baseline + labs")
merge_detail(m)
