#' Retrieves state/territory-level influenza statistics from the CDC (deprecated) #' #' Uses the data source from the CDC' State-levelFluView #' \url{https://gis.cdc.gov/grasp/fluview/main.html} and provides state flu #' reporting data as a single data frame.\cr #' \cr #' This function provides similar data to \code{\link{get_weekly_flu_report}} but #' provides more metadata about the reporting sources and has access to more #' historical infomation. #' #' @param years a vector of years to retrieve data for (i.e. \code{2014} for CDC #' flu season 2014-2015).
