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. 

January 2023 Guide can be accessed here.
