\title{Retrieve ILINet Surveillance Data}
|
|
\usage{
|
|
ilinet(region = c("national", "hhs", "census", "state"), years = NULL)
|
|
}
|
|
\arguments{
|
|
\item{region}{one of "\code{national}", "\code{hhs}", "\code{census}", or "\code{state}"}
|
|
|
|
\item{years}{a vector of years to retrieve data for (i.e. \code{2014} for CDC
|
|
flu season 2014-2015). CDC has data for this API going back to 1997.
|
|
Default value (\code{NULL}) means retrieve \strong{all} years. NOTE: if you
|
|
happen to specify a 2-digit season value (i.e. \code{57} == 2017-2018)
|
|
the function is smart enough to retrieve by season ID vs convert that
|
|
to a year.}

\description{
|
|
The CDC FluView Portal provides in-season and past seasons' national, regional,
|
|

|
|
ILINet (Influenza-like Illness Surveillance Network) and WHO/NREVSS
|
|
(National Respiratory and Enteric Virus Surveillance System).

|
}
|
|
\details{
|
|
This function retrieves current and historical ILINet surveillance data for
