annual_agg function

Create annual aggregations of WRTDS output

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

Returns

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

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.

Examples

## tidal object
annual_agg(tidfit)

## tidalmean object
annual_agg(tidfitmean)
