The Rnssp R package is a catalog of data processing and analytics tools, templates, and functions commonly used across the National Syndromic and Surveillance Program at the Centers for Disease Control and Prevention (CDC). Its goal is to improve code reproducibility, standardize and document reusable functions, facilitate the sharing of routine reports across the NSSP Community of Practice (CoP), and better engage the NSSP CoP.


You can install the development version of Rnssp from GitHub:

# install the Rnssp package


This is a basic example which shows you how to:

  • use the Rnssp package to create an NSSP user profile
  • and use the NSSP user profile to pull data from ESSENCE via the ESSENCE API

## Creating an NSSP user profile
myProfile <- Credentials$new(
  username = askme("Enter your username: "), 
  password = askme()

## Inspect your `myProfile` confirming that username and password are completely hidden

url <- "https://essence.syndromicsurveillance.org/nssp_essence/api/alerts/regionSyndromeAlerts?end_date=31Jan2021&start_date=29Jan2021"

## Pull Time Series Data from ESSENCE
api_data <- myProfile$get_api_data(url)

## Inspect data object structure

## Get a glimpse of the pulled dataset
