getNAA {discharge}

Net Annual Anomaly (NAA)

Description

Calculate Net Annual Anomaly (NAA) from the given residual values.

Usage

getNAA(resid, years, for.year = NULL)

Arguments

resid

A vector of residual values generated with respect to the baseline signal

years

A vector of years corrosponding to the residual values

for.year

(optional) Calculate NAA values only for the given year in this argument. If argument is omitted, NAA values for all years are calculated.

Value

Data frame containing two columns:

year	First column, represents year
NAA	Second column, represents NAA values

Examples

# load sample data
data("sycamore")
x = sycamore

# get streamflow object for the sample data
x.streamflow = asStreamflow(x)

# prepare baseline signal 
x.bl = prepareBaseline(x.streamflow)

# NAA
naa = getNAA(x.bl$resid.sig, x.streamflow$data$year)
