This function generates a dataframe similar to the
weather
dataset from nycflights13
for any US airports and time frame. Please
note that, even with a strong internet connection, this function
may take several minutes to download relevant data.
get_weather(station, year, month = 1:12, dir = NULL)
station | A character vector giving the origin US airports of interest (as the FAA LID airport code). |
---|---|
year | A numeric giving the year of interest. This argument is currently not vectorized, as dataset sizes for single years are significantly large. Information for the most recent year is usually available by February or March in the following year. |
month | A numeric giving the month(s) of interest. |
dir | An optional character string giving the directory to save datasets in. By default, datasets will not be saved to file. |
