baf

The goal of baf is to provide lightweight block assignment (and equivalence) files from the US Census Bureau.

Installation

You can install the development version of baf like so:

pak::pak('christopherkenny/baf')

Example

The workhorse function for baf is the baf() function.

library(baf)

baf(state = 'NM', year = 2024, geographies = 'cd')

Cache

By default, baf loads files to a temporary directory. To retain files across sessions, set the cache_to argument to a directory of your choosing. You can also set options(baf.use_cache = TRUE) to create a user-level cache that can persist across projects.
