Determine URLs to Radolan Files for Measurements

Determine the URLs to the Radolan files that are required to calibrate a model. For each day of measurement files (for the day of measurements and the five days before) are required.

get_radolan_urls_for_measurements(user_id, spot_id,
  sampling_time = "1050", date_range = NULL, all_in_range = FALSE,
  n_days_before = 5)

Arguments

user_id	user id
spot_id	bathing spot id
sampling_time	expected sampling time. Will be used to select the corresponding Radolan files.
date_range	vector of two Date objects giving the first and last day of rain data to be loaded. If NULL (the default) the range of dates is determined from the range of dates for which water quality measurements are available.
all_in_range	if TRUE (the default is FALSE) rain data for all days between the first and last day of a measurement are loaded. By default (all_in_range = FALSE), data for the days of measurement and for the days within a n_days_before-day time period before each day of measurement, are loaded.
n_days_before	number of days before a measurement for which to load rain data

Value

named vector of character containing the URLs to the Radolan files required for the measurements storted in the database. The names of the elements are strings in which the date and time is encoded in the format yyyymmddHHMM, e.g. "201809171050" for "2019-09-18 10:50"

Examples

if (FALSE) {
urls <- get_radolan_urls_for_measurements(user_id = 5, spot_id = 41)
}
