Fetches sub-daily observations for one or more stations across the requested
date range. The data source is determined automatically from the station
ID, or fixed explicitly via source.
Usage
hc_read_flows(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), timestamp (POSIXct
UTC), value (dbl), parameter (chr), unit (chr), provider_name
(chr), quality_code (chr), and qf_desc (chr).
Examples
# \donttest{
try(hc_read_flows("703", start_date = Sys.Date() - 7))
#> Warning: Station '703' not found in any data source. Skipping.
