extract_data: Overview of text data extraction functions

Description Details See Also


The following functions are intended to make it easy to extract relevant information from textual data. These functions are primarily intended for use in iso_mutate_file_info and inside the filtering conditions passed to iso_filter_files. However, they can of course also be used stand-alone and in regular mutate or filter calls on the data frames returned by the data retrieval functions (iso_get_raw_data, iso_get_file_info, iso_get_vendor_data_table, etc.). Not that all the parse_ functions are used in iso_parse_file_info for easy type conversions.


For simultaneous extraction of pure text data into multiple columns, please see the extract function from the tidyr package.
