plot.CAP: Draws cummulative abundance profiles

Description

Create plots used to inspect one or more cumulative abundance profiles.

Usage

# S3 method for CAP
plot(x, sizes=NULL, species=NULL, plots=NULL, switchAxes=FALSE, 
                   add=FALSE, drawAxes = TRUE, xlab="", ylab="", type="s",...)
# S3 method for stratifiedvegdata
plot(x, sizes=NULL, species=NULL, plots=NULL, switchAxes=FALSE, 
                   add=FALSE, drawAxes = TRUE, xlab="", ylab="", type="s",...)

Arguments

x: An object returned from function CAP or an object of class stratifiedvegdata (see documentation for function stratifyvegdata).
sizes: A vector containing the size values associated to each size class. If NULL the y-axis will be defined using the size class order in x.
species: A vector of strings indicating the species whose profile is to be drawn. If NULL all species are plotted.
plots: A vector indicating the plot records whose profile is to be drawn. Can be a character vector (for plot names), a numeric vector (for plot indices) or a logical vector (for TRUE/FALSE selection). If NULL all plot records are plotted.
switchAxes: A flag indicating whether ordinate and abscissa axes should be interchanged.
add: A flag indicating whether profiles should be drawn on top of current drawing area. If add=FALSE a new plot is created.
drawAxes: A flag indicating whether axes should be drawn.
xlab: String label for the x axis.
ylab: String label for the y axis.
type: Type of plot to be drawn ("p" for points, "l" for lines, "s" for steps, ...).
...: Additional plotting parameters.

Examples

Run this code

## Load stratified data
data(medreg)

## Check that 'medreg' has correct class
class(medreg)

## Create cumulative abundance profile (CAP) for each plot
medreg.CAP = CAP(medreg)

## Draw the stratified data and profile corresponding to the third plot
plot(medreg, plots="3")
plot(medreg.CAP, plots="3")

## Look at the plot and CAP of the same plot
medreg[["3"]]
medreg.CAP[["3"]]
