akq_globe: Global Summary of Count Tables from the Asquith-Knight...

In wasquith-usgs/akqdecay: Many Distributional Statistics of USGS Daily Streamflow Hydrographs and Powerful Utilities

Description

Produce global summary of the count tables from Asquith–Knight discharge decay analyses returned by akqdecay for a sequence of USGS streamgage identification numbers contained within an R environment. This environment has already been populated by fill_akqenv. The counts of number of sites, total (cumulative record length of daily values [minus the lag used for akqdecay?]) and totals for increasing, decreasing, no change, and missing days are computed.

Usage

akq_globe(akqenv, silent=TRUE, ...)

Arguments

akqenv	The R environment previously populated by fill_akqenv. This argument can also be an R list directly from akqdecay; special accommodation is made;
silent	Suppress informative calls to message(); and
...	Additional arguments to pass (see source code to ascertain flexible usage).

Value

An R list containing the following for all of the streamgages.

counts	The number sites plus totals of the various counts (integers); and
percents	The conversion of the counts to percent where total_count is treated as the sum total.
