ksCompare: smart data frame comparison

A tidyverse-native engine for comparing two data frames in the spirit of SAS PROC COMPARE, with extensions for clinical / pharma QC workflows.

Getting started

The single entry point is ks_compare():

library(ksCompare)

cmp <- ks_compare(adsl_prod, adsl_qc, by = "USUBJID")
cmp                       # console summary
tibble::as_tibble(cmp)    # long cell-level diff table
ks_report_html(cmp, "qc.html")

Building blocks

• ks_compare() – main entry point.

• ks_tol() – numeric tolerance (abs / rel / ULP, per-column).

• ks_comp_options() – NA, SAS special-missing, label / format, string normalisation, time-zone handling.

• ks_assert_clean() / ks_pointblank_step() – pipeline gates.

• ks_report_html() / ks_report_xlsx() – shareable reports.

• as_outbase() / as_outcomp() / as_outdif() / as_outnoequal() – PROC COMPARE-style output datasets.

• ks_sysinfo() – SAS &SYSINFO-compatible bitmask for CI.

ks_compare() also accepts file paths directly (.sas7bdat, .xpt, .parquet, .feather/.arrow, .rds, .rdata/.rda, .csv, .tsv) and chooses a reader based on the file extension.
