List all certifications stored in a certification file

Source: R/certify.R
list_certs.Rd

A convenience function to inspect what certification tags are stored and their key metadata, without needing to read the raw .rds file.

Usage

list_certs(file = ".reproducr")

Arguments

file

character(1). Base path of the certification store. Default ".reproducr".

Value

A data.frame with columns tag, timestamp, r_version, os, n_outputs, script – one row per certification. Returns an empty data frame if no certifications exist.

Examples

cert_file <- tempfile()
model <- lm(mpg ~ wt, data = mtcars)

certify(list(coefs = coef(model)), tag = "v1", file = cert_file)
#> reproducr: certified 1 output(s) [2026-06-10] under tag 'v1'
certify(list(coefs = coef(model)), tag = "v2", file = cert_file)
#> reproducr: certified 1 output(s) [2026-06-10] under tag 'v2'

list_certs(file = cert_file)
