Returns one water level value per station per calendar day as published by the data source. Not all data sources publish daily level data; those that do not will produce a warning and return no rows for the affected stations.
Usage
hc_read_daily_levels(
station_id,
start_date,
end_date = Sys.Date(),
source = NULL
)Arguments
- station_id
Character vector of station identifiers.
- start_date
Start of the requested period (Date, or character coercible to Date).
- end_date
End of the requested period (Date, or character coercible to Date). Defaults to today.
- source
Optional single character string naming the data source to use directly. When
NULL(default) the source is detected automatically from the station ID. Seehc_list_sources()for available names.
Value
A tibble with columns station_id (chr), date (Date),
value (dbl), parameter (chr: "water_level"), unit (chr),
provider_name (chr), quality_code (chr), and qf_desc (chr).
Examples
# \donttest{
try(hc_read_daily_levels("030101", start_date = "2020-01-01", end_date = "2020-01-31"))
