hy_sed_daily_suscon: Extract daily suspended sediment concentration information...

In tidyhydat: Extract and Tidy Canadian 'Hydrometric' Data

Extract daily suspended sediment concentration information from the HYDAT database

Description

Provides wrapper to turn the SED_DLY_SUSCON table in HYDAT into a tidy data frame of daily suspended sediment concentration information. station_number and prov_terr_state_loc can both be supplied. If both are omitted all values from the hy_stations table are returned. That is a large vector for hy_sed_daily_suscon.

Usage

hy_sed_daily_suscon(
  station_number = NULL,
  hydat_path = NULL,
  prov_terr_state_loc = NULL,
  start_date = NULL,
  end_date = NULL,
  symbol_output = "code"
)

Arguments

station_number	A seven digit Water Survey of Canada station number. If this argument is omitted, the value of prov_terr_state_loc is returned.
hydat_path	The path to the hydat database or NULL to use the default location used by download_hydat. It is also possible to pass in an existing src_sqlite such that the database only needs to be opened once per user-level call.
prov_terr_state_loc	Province, state or territory. If this argument is omitted, the value of station_number is returned. See unique(allstations$prov_terr_state_loc). Will also accept CA to return only Canadian stations.
start_date	Leave blank if all dates are required. Date format needs to be in YYYY-MM-DD. Date is inclusive.
end_date	Leave blank if all dates are required. Date format needs to be in YYYY-MM-DD. Date is inclusive.
symbol_output	Set whether the raw code, or the english or the french translations are outputted. Default value is code.
