get_hosp_data(area = "flusurvnet", age_group = "overall",
  years = as.numeric(format(Sys.Date(), "%Y")) - 1)

Arguments

area

one of "flusurvnet", "eip", "ihsp", or two digit state abbreviation for an individual site. Exceptions are New York - Albany ("nya") and New York - Rochester ("nyr")

age_group

a vector of age groups to pull data for. Possible values are: "overall", "0-4y", "5-17y, "18-49y, "50-64y, "65+y".

years

a vector of years to retrieve data for (i.e. 2014 for CDC flu season 2014-2015). Default value is the current year and all years values should be >= 2009

Value

A single data.frame.

Note

There is often a noticeable delay when making the API request to the CDC. This is not due to a large download size, but the time it takes for their servers to crunch the data. Wrap the function call in httr::with_verbose if you would like to see what's going on.
