ww_wyUSGS: Water Year Stats (USGS)

In joshualerickson/whitewater: Parallel Processing Options for Package 'dataRetrieval'

Water Year Stats (USGS)

Description

This function uses the results of the ww_dvUSGS object to generate mean, maximum, median, standard deviation and some normalization methods (drainage area, scaled by log and standard deviation) per water year.

Usage

ww_wyUSGS(procDV, sites = NULL, parallel = FALSE, verbose = TRUE, ...)

Arguments

procDV	A previously created ww_dvUSGS object.
sites	A character vector with NWIS site numbers (optional).
parallel	logical indicating whether to use future_map().
verbose	logical for printing information. TRUE (default).
...	arguments to pass on to future_map and/or ww_dvUSGS.

Value

A tibble filtered by water year with added meta-data.

Note

If a previously created ww_dvUSGS object is not used then the user needs to provide a sites vector. This will run ww_dvUSGS in the background.

Examples

## Not run: 

library(whitewater)
yaak_river_dv <- ww_dvUSGS('12304500',
parameter_cd = '00060',
wy_month = 10)

yaak_river_wy <- ww_wyUSGS(yaak_river_dv)

#parallel

#get sites

huc17_sites <- dataRetrieval::whatNWISdata(huc = 17,
siteStatus = 'active',
service = 'dv',
parameterCd = '00060')

library(future)
#need to call future::plan()
plan(multisession(workers = availableCores()-1))

pnw_dv <- ww_dvUSGS(huc17_sites$site_no,
parameter_cd = '00060',
wy_month = 10,
parallel = TRUE)

pnw_wy <- ww_wyUSGS(pnw_dv,
                    parallel = TRUE)
