fred (version 0.3.1)

fred_browse: Browse the FRED category tree

Description

Pretty-prints the FRED category tree. With no arguments, shows the eight top-level FRED categories from a built-in static reference (no API call). Pass a category_id to drill into its children, which fetches from the API (and is cached). Use this to discover where series live before searching inside a category with fred_category_series().

Usage

fred_browse(category_id = 0L, depth = 1L)

Value

A fred_tbl of categories at the requested level (invisibly).

Arguments

category_id

Integer. Category to browse. Default 0 (root). The root prints from a static reference and does not call the API.

depth

Integer. How many levels deep to recurse. Default 1 (only immediate children). Higher values trigger one API call per parent category visited.
