#' Retrieve Flu Season Data from the United States Centers for Disease Control and Prevention ('CDC') 'FluView' Portal

|
|
#' The U.S. Centers for Disease Control (CDC) maintains a portal
|
|
|
|
#' <http://gis.cdc.gov/grasp/fluview/fluportaldashboard.html> for
|
|
|
|
#' accessing state, regional and national influenza statistics as well as
|
|
|
|
#' Mortality Surveillance Data. The Flash interface makes it difficult and
|
|
|
|
#' time-consuming to select and retrieve influenza data. This package
|
|
|
|
#' provides functions to access the data provided by the portal's underlying API.
