annual_agg: Create annual aggregations of WRTDS output

In fawda123/WRTDStidal: Weighted Regression for Water Quality Evaluation in Tidal Waters

Create annual aggregations of WRTDS output

Description

Create annual aggregations of WRTDS output

Usage

annual_agg(dat_in, ...)

## Default S3 method:
annual_agg(dat_in, mo_strt = 10, min_mo = 9, logspace = TRUE, ...)

Arguments

dat_in	input tidal or tidalmean object
...	arguments passed to or from other methods
mo_strt	numeric indicating month to start aggregation years, defaults to October for USGS water year from October to September
min_mo	numeric value from one to twelve indicating the minimum number of months with observations for averaging by years
logspace	logical indicating if aggregated data are to be shown in log-space or not

Details

WRTDS output is averaged by year for both predictions and flow-normalized predictions. Years are averaged only if one observation is contained in each of the minimum number of months specified by min_mo averaging, otherwise results are not returned for the given year. Note that setting min_mo to values smaller than the default can produce inaccurate trends for years with very few results.

The function is used internally within prdnrmplot and fitplot.

Value

An aggregated data object for plotting, returns only model output and response variable.

Examples

## tidal object
annual_agg(tidfit)

## tidalmean object
annual_agg(tidfitmean)
