Adapt Admin Express archives — adapt_admin

adapt_admin_express treats Admin Express archives to be in a standard format. It is suited for IGN archives. It used by default scheme_admin_express_3_1 as scheme. For older versions scheme_admin_express_2_0 is also available.

Beware that codeadapt_admin_express will perform all possibles combinations of archives present in origin and layers available in scheme if those parameters are not specified.

adapt_admin_express(
  origin,
  destination,
  archive,
  layer = NULL,
  scheme = floodam.data::scheme_admin_express_3_1,
  projection = 4326,
  extension = "rds",
  journal = TRUE,
  retrieve = FALSE,
  verbose = TRUE
)

Arguments

origin: character, path to the directory where archive are stored.
destination: character, path to the directory where results should be saved.
archive: character, vector of archive to be adpated.
layer: character, which layer should be treated.
scheme: data.frame, how archive variables should be treated.
projection: integer or object of type CRS giving projection.
extension: character, option for extension and so format of saving of results.
journal: logical, should a journal file be saved.
retrieve: logical, should the result be returned.
verbose: logical, should the function give some sumup informations.

Value

if retrieve = TRUE, sf object of adapated data stored in archive. This may be a list if the function implies recursive calls.

Details

The following treatment are performed:

depending on how many archives and layers are to be treated, a recursive call may be perform to do all desired combinations.
archive is read with read_with_scheme(), which may imply that it is uncompressed, then read (usually as a shp or a gpkg file), reprojected if asked, and finally adapted.
the output is saved as rds in given destination withesave_archive(). The name of archive include a precision depending on the layer chosen. For layer 'COMMUNE', the saving is made by departments.
