 `get_speed.R` Do we need this doesn't seem to get use only the gcd.slc?  | Also contains function [gcd.slc](https://git.noc.ac.uk/brecinosrivas/icoads-r-hostace/-/blob/master/rutils/get_isolated.R#L10): Calculates the geodesic distance between two points specified by radian latitude/longitude using the spherical law of cosines ([slc](https://en.wikipedia.org/wiki/Spherical_law_of_cosines)).
 [`id_group_func.R`](https://git.noc.ac.uk/brecinosrivas/icoads-r-hostace/-/blob/master/rutils/id_group_func.R)   | Makes sure that all `id`'s grouped in [`get_groups.R`](https://git.noc.ac.uk/brecinosrivas/icoads-r-hostace/-/blob/master/rutils/get_groups.R) are properly associated.

+[`liz_merge.R`](https://git.noc.ac.uk/brecinosrivas/icoads-r-hostace/-/blob/master/rutils/liz_merge.R)   | Merges two data frames by specific columns. 
+[`new_add_match_id.R`](https://git.noc.ac.uk/brecinosrivas/icoads-r-hostace/-/blob/master/rutils/new_add_match_id.R)   |  Tests whether paired `id`'s  are allow to match according a [matching criteria](Workflow/matching-criteria) and by using the [Damerau–Levenshtein (DL) distance](https://en.wikipedia.org/wiki/Damerau%E2%80%93Levenshtein_distance) formula.
+`new_homog_ids.R`   | Uses standard linkages between `id`'s to add `id` [homogenisation](Workflow/processing-of-ids) information to each records.
+`print_id_match_info.R`   | Prints ICOADS duplicates information and `id` matching results.
+`read_rdsfiles.R`   | A collection of functions to read all different types of data files (e.g rds, .txt) used through out the code. 
+`write_dup_func.R`  | Writes duplicate information in a pipe-delimited year-month output format. The report `uid` is followed by the report `id` then a flag with value 1 if the `id` has been changed, 0 if it remains the same. <br> An example of the format is: <br> ICOADS-30-0Y0HJK &#124; 32024 &#124; 0 <br> ICOADS-30-0Y0HJL &#124; 14 00117 &#124; 1
