display.SAP: Function to plot slope vs. area.

In coffeemuggler/RCHILD: Functions for flexible use of the landscape evolution model CHILD

Description

This function creates a plot of slope va. area for all interiour nodes of a CHILD model run, for each specified time step separately. The plot data sets are returned as well.

Usage

display.SAP(dataset, timesteps, plot = TRUE, ...)

Arguments

dataset	(S4-object) CHILD model run output data set.
timesteps	(numeric vector) Time steps use for calculation. If missing, all modelled time steps are used.
plot	(logical scalar) Option to show or hide plot output (dafault is TRUE).
...	Further plot parameters to pass to the plot object.

Details

Value

A list object

data	A list with area and slope data per time step.
ranges	A matrix with data ranges of area and slope.

Examples

# load example data set
data(hillslope1)

# plot slope vs. area for time steps 2 to 5 in a log-log-plot
SAP <- display.SAP(hillslope1, 
                  timesteps = 2:5, 
                  main = "Slope-area-plot", 
                  xlab = "area [square metres]", 
                  ylab = "slope [degree]",
                  log = "xy",
                  cex = 0.4)

# show some numeric output for time step 2
