Usage

timeseries(
  x,
  parameter,
  stations = NULL,
  start_date = NULL,
  end_date = NULL,
  mode = c("range", "complete"),
  ...
)

Arguments

x: A hydro_service object created by hydro_service().
parameter: One of "water_discharge","water_level","water_temperature","water_velocity".
stations: Optional character vector of station IDs.
start_date, end_date: YYYY-MM-DD strings for mode = "range".
mode: Either "range" or "complete" (1900-01-01 to today).
...: Passed to provider-specific methods.

Value

A tibble with columns: country, provider_id, provider_name, station_id, parameter, timestamp, value, unit, quality_code, source_url.

Examples

# Offline: construct a service object (no network)
x <- hydro_service("SE_SMHI")

if (FALSE) { # interactive() && requireNamespace("curl", quietly = TRUE) && curl::has_internet() && identical(Sys.getenv("HYDRO_EXAMPLES"), "true")
# Online (opt-in): one station for a short range
st <- head(stations(x)$station_id, 1)
ts <- timeseries(x, parameter = "water_discharge",
                 stations = st,
                 start_date = "2020-01-01", end_date = "2020-01-10")
head(ts)
}
