Calculates and draws rhizosphere, root, stem and leaf resistances for simulation time steps
resistances(
x,
cohort,
relative = FALSE,
draw = FALSE,
cumulative = FALSE,
xlab = NULL,
ylab = NULL
)If draw = FALSE, the function returns list with three items:
pathway: A data frame with dates in rows and resistance segments in columns (Rhizosphere, Root, Stem and Leaf).
root: A data frame with dates in rows and root resistances for soil layers in columns.
rhizosphere: A data frame with dates in rows and rhizosphere resistances for soil layers in columns.
Values depend on whether relative = TRUE (percentages) or relative = FALSE (absolute resistance values).
If draw = TRUE, a plot object is returned showing the time series of pathway resistances.
An object of class spwb, pwb, growth or fordyn.
The function only works with the result of simulations with transpirationMode = "Sperry" or transpirationMode = "Sureau".
An string indicating the cohort for which resistances are desired.
A boolean flag to indicate that relative percentages are desired as output.
A boolean flag to indicate that a plot should be drawn (only pathway resistances, without discriminating between soil layers).
A flag to indicate that drawn series should be cumulative.
x-axis label.
y-axis label.

The function makes internal calls to hydraulics_soilPlantResistancesWeibull or
hydraulics_soilPlantResistancesSigmoid depending on the value of transpirationMode in x.
