get_variety_db: Return cultivar names along with unique internal identifier...

In IdahoAgStats/factcuratoR: Functions to curate FACT data

Return cultivar names along with unique internal identifier (no spaces or special characters)

Description

Filter the cultivar list by the date that the cultivar was added. The default value selects before current date. If select_before = NULL, then all dates will be returned. Recommended usage for curation is to use the current date, so that the curation is reproducible even as the cultivar list is being continuously updated.

Usage

get_variety_db(
  db_folder,
  select_before = Sys.Date(),
  select_crops = NULL,
  for_matching = FALSE
)

get.variety_db(
  db_folder,
  select_before = "2021-01-01",
  select_crops = NULL,
  for_matching = FALSE
)

Arguments

db_folder	A string path to the database controlled vocabulary folder
select_before	A string in the format of Ymd. The function returns cultivars that were added to the datebase before this specified date.
select_crops	A regular expression of crops separated by |. Note that this regex will filter on the crop column rather than crop_type. For example, there are entries in the wheat file with crop Triticale, so to capture both the input should be select_crops = "wheat|triticale".
for_matching	logical, whether the result will be used for matching. Default is FALSE.

Details

Cultivar names are stored by crop_type, this function will return all the requested crop_types.
