The package is pristine at CRAN https://cran.r-project.org/web/checks/check_results_data.table.html (apart from some new warnings several packages now get about interal R API headers, nothing to do with tests)
Maybe you can sort this with upstream -- data.table is effectively holding up r-base (and has been for months since the R 4.3.3 release) which is not exactly ideal. Dirk -- dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org
