age_group_distribution

<p>a vector of years to retrieve data for (i.e. `2014` for CDC
flu season 2014-2015). CDC has data for this API going back to 1997.
Default value (`NULL`) means retrieve **all** years. NOTE: if you
happen to specify a 2-digit season value (i.e. `57` == 2017-2018)
the function is smart enough to retrieve by season ID vs convert that
to a year.</p>

years

<p>Retrieves the age group distribution of influenza positive tests that are reported by
public health laboratories by influenza virus type and subtype/lineage. Laboratory data
from multiple seasons and different age groups is provided.</p>

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 web interface makes it difficult and
time-consuming to select and retrieve influenza data. Tools are provided
to access the data provided by the portal's underlying 'API'.
