medfate (version 2.8.0)

resistances: Soil-plant resistances

Description

Calculates and draws rhizosphere, root, stem and leaf resistances for simulation time steps

Usage

resistances(x, cohort, relative = FALSE, draw = FALSE, 
            cumulative = FALSE, xlab = NULL, ylab = NULL)

Value

A data frame with dates in rows and resistance segments in columns (Rhizosphere, Root, Stem and Leaf). Values depend on whether relative = TRUE (percentages) or relative = FALSE (absolute resistance values). If draw = TRUE then a plot object is returned.

Arguments

x

An object of class spwb, pwb, growth or fordyn. The function only works with the result of simulations with transpirationMode = "Sperry".

cohort

An string indicating the cohort for which resistances are desired.

relative

A boolean flag to indicate that relative percentages are desired as output

draw

A boolean flag to indicate that a plot should be drawn.

cumulative

A flag to indicate that drawn series should be cumulative.

xlab

x-axis label.

ylab

y-axis label.
