The nihexporter R package provides a minimal set of data from the NIH EXPORTER database, which contains information on NIH biomedical research funding from 1985-2024.

To keep the package lightweight, many details are omitted but can be easily retrieved from NIH RePORTER.

Install the package from github with:

# install.packages('pak')
pak::pak("rnabioco/nihexporter")
