pkgstats_fns_from_archive( path, archive = FALSE, prev_results = NULL, results_file = NULL, chunk_size = 1000L, num_cores = 1L, results_path = tempdir() )
Path to local archive of R packages, either as source directories, or '.tar.gz' files such as in a CRAN mirror.
TRUE, extract statistics for all packages in the
/Archivesub-directory, otherwise only statistics for main directory (that is, current packages only).
Result of previous call to this function, if available. Submitting previous results will ensure that only newer packages not present in previous result will be analysed, with new results simply appended to previous results. This parameter can also specify a file to be read with
Can be used to specify the name or full path of a
.Rdsfile to which results should be saved once they have been generated. The '.Rds' extension will be automatically appended, and any other extensions will be ignored.
Divide large archive trawl into chunks of this size, and save intermediate results to local files. These intermediate files can be combined to generate a single
prev_resultsfile, to enable jobs to be stopped and re-started without having to recalculate all results. These files will be named
pkgstats-results-N.Rds, where "N" incrementally numbers each file.
Number of machine cores to use in parallel, defaulting to single-core processing.
Path to save intermediate files generated by the
chunk_sizeparameter described above.
