getFPExt function

Flood Pulse Extent (FPExt)

Calculate the Flood Pulse Extent (FPExt) from the given residual values.

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

Returns

Data frame containing two columns:

year	First column, represents year
FPExt	Second column, represents FPExt 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)

# FPExt
fpext = getFPExt(x.bl$resid.sig, x.streamflow$data$year)
