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)
