dmcurve: Double Mass Curve

In lfstat: Calculation of Low Flow Statistics for Daily Stream Flow Data

Description

Calculates the double mass curve of two object of class 'lfobj'.

Usage

dmcurve(x, y, year = "any", namex = substitute(x), namey = substitute(y), 
    na.rm = TRUE) 

Arguments

x	An object of class "lfobj"
y	An object of class "lfobj"
year	The year for which the dmcuve should be calculated
namex	character - Label of the x-Axis in the dmcurve
namey	character - Label of the y-Axis in the dmcurve
na.rm	Remove NAs?

Examples

data(ngaruroro)
n1 <- subset(ngaruroro, year %in% 1985:1989)

dmcurve(n1,n2, namex = "'Ngaruroro 1985 - 1989'", namey = "'Ngaruroro 1990
- 1995'")
