In July 2021, NSSP announced the release of the Rnssp R package which facilitates access to the ESSENCE system via a secure and simple interface. Rnssp provides methods that streamline the data pull and simplify R code previously required by users to pull data via the APIs using the keyring library. In this tutorial demonstrates how to pull data from the ESSENCE system using Rnssp.

This RStudio API guide provides an overview of the ESSENCE APIs and how to access them through RStudio. We will begin with a very brief explanation of application programming interfaces (APIs), then list what APIs are available in ESSENCE, and finally expose you to basic examples of R code and packages so that you can start using RStudio to access ESSENCE data, create your own R Markdown reports and Shiny applications, or do exploratory analyses not possible within ESSENCE.
