fredr 2.1.0.9000

fredr() / fredr_series_observations() now always return realtime_start and realtime_end columns. These are useful when setting the realtime_start / realtime_end arguments, or when using the vintage_dates argument (#88).
Fixed a bug in fredr() / fredr_series_observations() so that now the vintage_dates argument properly accepts a Date vector of length 1 or greater (#89).

fredr has been un-orphaned!
If the FRED rate limit is hit, all fredr functions will now wait an appropriate amount of time before automatically attempting to make the request again. The rate limit seems to be 120 requests per minute, so fredr functions will wait 20 seconds between failed attempts, with a maximum of 6 failed attempts. This should be plenty of time for the rate limit to reset.
Required arguments no longer have a default of NULL. This should make it easier to visually distinguish between required and optional arguments. Additionally, ... have been added between the required and optional arguments of every function to force naming of optional arguments.
All requests to the FRED API are now retried a maximum of 3 times on failure. The low level function, fredr_request(), has gained a retry_times argument if you need to change this on a case-by-case basis.
There are two new functions related to the API key, fredr_set_key() and fredr_has_key(). These are mainly for internal usage.

Initial release for CRAN. All endpoint functions for the FRED API are now implemented as functions in fredr.

fredr() -> fredr_request() (#46)
fredr_series() -> fredr_series_observations() (alias: fredr()) (alias: fredr()) now returns a tibble (with observation date, series ID, and values columns) instead of a time series object (#46, #49).
Remove dependencies dplyr and xts (#9).
fred_set_key() no longer modifies .Renviron. User is encouraged to manually change .Renviron to persistently set FRED API key (#15).
Explicit parameters and parameter checking for all functions (#20).
Split fredr_search() into
- fredr_series_search_text() (search for series by text description)
- fredr_series_search_text() (search for series)
- fredr_series_search_tags() (search for series tags)
- fredr_series_search_related_tags() (search for related tags)
