nihexporter

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.

Installation

Install the package from github with:

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

⚠️Note: this is a large data package (>50 Mb) and will take some time to download and install. ⚠️
