Description Usage Arguments Value See Also Examples

Given a valid station and a single date this function will return a dataframe of time-stamped weather data. All the records are summarized into one record per day. If and end_date is specified the function returns 1 record for each day in the date range.

getSummarizedWeather(station_id, start_date, end_date = NULL,
  station_type = "airportCode", opt_temperature_columns = TRUE,
  opt_all_columns = FALSE, opt_custom_columns = FALSE,
  custom_columns = NULL, opt_verbose = FALSE)

`station_id`	is a valid 3-letter airport code
`start_date`	string representing a date in the past ("YYYY-MM-DD")
`end_date`	(optional) string representing a date in the past ("YYYY-MM-DD"), and later than or equal to start_date.
`station_type`	can be `airportCode` which is the default, or it can be `id` which is a weather-station ID
`opt_temperature_columns`	Boolen flag to indicate only Temperature data is to be returned (default TRUE)
`opt_all_columns`	Boolen flag to indicate whether all available data is to be returned (default FALSE)
`opt_custom_columns`	Boolen flag to indicate if only a user-specified set of columns are to be returned. (default FALSE) If TRUE, then the desired columns must be specified via `custom_columns`
`custom_columns`	Vector of integers specified by the user to indicate which columns to fetch. The Date column is always returned as the first column. The column numbers specfied in `custom_columns` are appended as columns of the data frame being returned (default NULL). The exact column numbers can be found by visiting the weatherUnderground URL, and counting from 1. Note that if `opt_custom_columns` is TRUE, then `custom_columns` must be specified.
`opt_verbose`	Boolean flag to indicate if verbose output is desired

A data frame with each row containing:

Date stamp for the date specified
Additional columns of Weather data depending on the options specified
