lfnainterpolate {lfstat}

Interpolate missing values

Description

If a low flow object contains missing values, the missing values are replaced by connecting the last available value before the break and the first after the break by a straight line.

Usage

lfnainterpolate(lfobj)

Arguments

lfobj

An object of class "lfobj"

Value

lfobj

An object of class "lfobj"

with interpolated missing values

Warning

Check carefully in advance if interpolation is a reasonable choice for filling the hydrograph

Examples

data(ngaruroro)

# Part of the ngaruroro series with missing data
hydrograph(ngaruroro, startdate = "1/7/1987", enddate = "1/9/1987",amin = FALSE)

ngaruroroint <- lfnainterpolate(ngaruroro)

# The completed hydrograph
hydrograph(ngaruroroint, startdate = "1/7/1987", enddate = "1/9/1987",amin = FALSE)
