  cache_dir = NULL, compress_file = TRUE, verbose = FALSE, ...)

Arguments

id

a character string with the id of the dataset. It is the value from the codename column of the get_eurostat_toc function.

cache

a boolean whether to load/save the TOC from/in the cache or not. The default value is TRUE, so that the TOC is checked first in the cache and if does not exist then downloaded from Eurostat and cached.

update_cache

a boolean to update cache or not. The default value is FALSE, so the cache is not updated. Can be set also with options(restatapi_update=TRUE)

cache_dir

a path to a cache directory. The default is NULL, in this case the TOC is cached in the memory (in the '.restatapi_env'). Otherwise if the cache_dir directory does not exist it creates the 'restatapi' directory in the temporary directory from tempdir() to save the RDS-file. Directory can also be set with option(restatapi_cache_dir=...).

compress_file

a logical whether to compress the RDS-file in caching. Default is TRUE.

verbose

A boolean with default FALSE, so detailed messages (for debugging) will not printed. Can be set also with options(restatapi_verbose=TRUE)

...

parameter to pass on the load_cfg function

Details

The DSD is downloaded from Eurostat's website, through the REST API in XML (SDMX) format.
