Reconfigures Batch Processing File Set

Updates the regular expression and/or recurse argument that were provided when a directory was configured (using batch_config()).

batch_reconfig_fileset(path, regexp = NULL, recurse = NULL)

Arguments

path

A string of the path to the directory with the files for processing.

regexp

A string of a regular expression. Only non-hidden file names which match the regular expression will be batch processed.

recurse

A flag specifying whether to recurse into path's subdirectories.

Value

An invisible character vector of the paths to the files remaining to be processed.

Details

batch_reconfig_fileset() is useful for including or excluding particular files.

It should be noted that batch_reconfig_fun() does not alter the configuration time.

In order to process previously failed files batch_run() should be called with failed = NA or failed = TRUE.
