This vignette is intended to introduce the user to fredr functions for the Sources endpoint of the FRED API.
FRED series are derived from a specific data source. Each FRED source is assigned an integer identifier. The following examples illustrate usage of the Sources endpoint functions in fredr.
fredr_sources() returns a list of FRED data sources. The information returned is a tibble in which each row represents a FRED source. For example, running
fredr_sources() without any arguments returns the first 1000 (
limit default) sources ordered by ascending source ID (but here we limit to just 10):
fredr_sources(limit = 10)
fredr_source() returns information for a single source indicated by
source_id. The data returned is a tibble in which each row represents a FRED source. For example, the Federal Financial Institutions Examination Council source ID is
fredr_source(source_id = 6L)
fredr_source_releases() returns FRED release information for the source indicated by
source_id. As with the functions for the Releases endpoint, the data returned is a tibble in which each row represents a FRED release for the specified source. For example, to get the first 10 releases from the Federal Reserve Board of Governors, ordered by ascending release ID:
fredr_source_releases( source_id = 1L, limit = 10L )
To get University of Michigan releases since 1950:
fredr_source_releases( source_id = 14L, realtime_start = as.Date("1950-01-01") )
