In cmu-delphi/epiprocess: Tools for basic signal processing in epidemiology

Given a tibble as would be found in an epi_archive, remove duplicate entries.

Description

Works by shifting all rows except the version, then comparing values to see if they've changed. We need to arrange in descending order, but note that we don't need to group, since at least one column other than version has changed, and so is kept.

Usage

apply_compactify(updates_df, ukey_names, abs_tol = 0)

Arguments

updates_df	DT of an epi_archive or something analogous (though potentially unsorted) of another class
ukey_names	chr; the column names forming a unique key for the updates_df; "version" must come last. For an epi_archive's DT, this would be key(DT).
abs_tol	numeric, >=0; absolute tolerance to use on numeric measurement columns when determining whether something can be compactified away; see is_locf
