Get the related FRED tags within a category

Description

Get the related FRED tags for one or more FRED tags within a category. Optionally, filter results by tag group or search. FRED tags are attributes assigned to series. Related FRED tags are the tags assigned to series that match all tags in the tag_names parameter, no tags in the exclude_tag_names parameter, and the category set by the category_id parameter. Series are assigned tags and categories. Indirectly through series, it is possible to get the tags for a category. No tags exist for a category that does not have series.

Usage

fredr_category_related_tags(
  category_id,
  tag_names,
  ...,
  exclude_tag_names = NULL,
  tag_group_id = NULL,
  search_text = NULL,
  limit = NULL,
  offset = NULL,
  order_by = NULL,
  sort_order = NULL,
  realtime_start = NULL,
  realtime_end = NULL
)

Arguments

category_id	An integer ID for the category.
tag_names	A string indicating which series tags to match. Multiple tags can be delimited by a semicolon in a single string (e.g. "usa;gnp").

exclude_tag_names	A string indicating which series tags should not be matched. Multiple tags can be delimited by a semicolon in a single string (e.g. '"usa;gnp"“).
tag_group_id	A string representing the tag group id to filter tags by type. No filtering by default. Possible values include: "freq" - Frequency "gen" - General or Concept "geo" - Geography "geot" - Geography Type "rls" - Release "seas" - Seasonal Adjustment "src" - Source
search_text	A string to match text of tags. No matching by default.
limit	An positive integer indicating maximum number of results to return. Possible values are any integer between 1 and 1000 (default), inclusive.
offset	An non-negative integer used in conjunction with limit for long series. This mimics the idea of pagination to retrieve large amounts of data over multiple calls. Defaults to 0.
order_by	Order results by values of the specified attribute. Possible values include: "series_count" (default), ⁠"popularity"``, ⁠"created"⁠, ⁠"name"⁠, ⁠"group_id"'.
sort_order	A string representing the order of the resulting series. Possible values are: "asc" (default), and "desc".
realtime_start	A Date indicating the start of the real-time period. Defaults to today's date. For more information, see Real-Time Periods.

Send a request to the FRED API

Description

Send a general request to the FRED API by specifying an endpoint and a sequence of parameters. The fredr_request() function forms and submits a request to a specified endpoint of the FRED API. The result is either the response object from httr::GET() or the response parsed as a tibble.

  print_req = FALSE,
  retry_times = 3L
)

Arguments

endpoint	A string representing the FRED API endpoint of interest. See fredr_endpoints for a list of endpoint possible values. Required parameter.
...	A series of named parameters to be used in the query. Must be of the form param_key = "param_value". Acceptable parameters are endpoint-specific. See the fredr_endpoints data frame for a list of endpoints and fredr_docs() to access the web documentation for each endpoint function.
to_frame	A boolean value indicating whether or not the response should be parsed and formatted as a data frame. If FALSE, a response object is returned and further processing can be done with httr::content(). Default is TRUE.
print_req	A boolean value indicating whether or not the request should be printed as well. Useful for debugging. Default is FALSE.
retry_times	An integer indicating the maximum number of requests to attempt. Passed directly to httr::RETRY(). Default is 3.

tag_group_id	A string tag group id to filter tags by type. No filtering by tag group by default. Possible values are: "freq" = Frequency "gen" = General or Concept "geo" = Geography "geot" = Geography Type "rls" = Release "seas" = Seasonal Adjustment "src" = Source
search_text	A string indicating the words to find matching tags with. No filtering by search words by default.
limit	An integer limit on the maximum number of results to return. Defaults to 1000, the maximum.
offset	An integer used in conjunction with limit for long series. This mimics the idea of pagination to retrieve large amounts of data over multiple calls. Defaults to 0.
order_by	Order results by values of the specified attribute. Possible values are: "series_count" (default) "popularity" "created" "name" "group_id"
sort_order	A string representing the order of the resulting series, sorted by the attribute values specified by order_by. Possible values are: "asc" (default), and "desc".
realtime_start	A Date indicating the start of the real-time period. Defaults to today's date. For more information, see Real-Time Periods.
realtime_end	A Date indicating the end of the real-time period. Defaults to today's date. For more information, see Real-Time Periods.

Value

FRED API key

Description

Users of fredr must authenticate with the FRED API by use of an API key. This key should be stored as an environment variable, FRED_API_KEY.

• fredr_get_key() will retrieve the key, if set, or it will return NULL if the key is unset.

• fredr_set_key() will set the key for the current R session. For persistence across sessions, set the environment variable. See the Details section for more information.

• fredr_has_key() returns TRUE if a key can be found. Otherwise it returns FALSE.

Usage

fredr_set_key(key)

fredr_get_key()

fredr_has_key()

Arguments

key	A valid FRED API key as a string. Obtain one at the API Keys page. Can also be NULL to unset the key for the current R session.

Details

The preferred method to set the key is to set the FRED_API_KEY environment variable in an .Renviron file. The easiest way to do this is by calling usethis::edit_r_environ(). Don't forget to restart R after setting the key.

References

See St. Louis Fed Web Services API Keys to obtain an API key.

See Also

Note that by using a FRED API key, you agree to the FRED API Terms of Use.

Examples

original_key <- fredr_get_key()

# Set a once per session key
fredr_set_key("foo")

# Get it
fredr_get_key()

# Reset to original key
fredr_set_key(original_key)
