Usage

pxweb_advanced_get(
  url,
  query = NULL,
  verbose = TRUE,
  log_http_calls = FALSE,
  pxmdo = NULL,
  ...
)

url: a pxweb object or url that can be coherced to a pxweb object.
query: a json string, json file or list object that can be coherced to a pxweb_query object.
verbose: should large queries print out progress.
log_http_calls: Should the http calls to the API be logged (for debugging reasons). If TRUE, all calls and responses are logged and written to "log_pxweb_api_http_calls.txt" in the working directory.
pxmdo: A pxweb_metadata object to use for query.
...: Further arguments sent to httr::POST (for queries) or httr::GET (for query = NULL). If used with query, also supply a pxweb_metadata object. Otherwise the same parameters are sent to both httr::POST and httr::GET.

This function is intended for more advanced users that want to supply specific arguments in httr calls or what to debug httr calls.

pxweb_get() is a wrapper for standard use.
