Basic Usage

# before making any calls you will need to set your app_id and app_key
> Authenticate("your_app_id", "your_app_key")

# set up some variables to make calls with
> lat <- 35
> lon <- -97
> start <- '2016-01-01'
> end <- '2016-01-31'

> gdd <- GrowingDegreeDays (lat, lon, start, end)  
> gdd$response$status_code == 200
[1] TRUE

> summary(gdd$content$series[[3]])
