This function gets a data frame containing path information as input. It
filters for rows with value "file" in column type and keeps only the
columns path and size. If pattern is not NULL,
the data frame is then filtered for rows in which path matches the
given pattern. Finally, the common root of all paths in column path is
removed and the resulting data frame is returned.
prepare_path_data(path_info, pattern = NULL)data frame containing file path information as returned by
read_file_info
pattern by which to select a subset of paths or NULL
(default) if all paths in path_info are to be considered. By
setting the pattern to "^/path/to/start/directory" you can "zoom into" the
path tree, returning only the contents of "/path/to/start/directory".
data frame with columns path and size. See Description.
