If the API key is provided, sets the environmental variable. You can set your API key in four ways:
the API key (obtained from https://quickstats.nass.usda.gov/api)
directly or as a variable from your
nassqs_auth(key = "<your api key>"
NASSQS_TOKEN in your
R environment file (you'll never have
to enter it again).
by entering it into the console when asked (it will be stored for the rest of the session.)
# Set the API key nassqs_auth(key = "<your api key>") Sys.getenv("NASSQS_TOKEN")#>  "<your api key>"
