In ade4: Analysis of Ecological Data : Exploratory and Euclidean Methods in Environmental Sciences

Description

rtest is a generic function. It proposes methods for the following objects between, discrimin, procuste ...

Usage

    rtest(xtest, ...)
    ## S3 method for class 'rtest'
plot(x, nclass = 10, coeff = 1, ...)
    as.rtest (sim, obs, call = match.call())
    ## S3 method for class 'rtest'
print(x, ...)

Arguments

xtest	an object used to select a method
x	an object of class 'rtest'
...	further arguments passed to or from other methods; in plot.randtest to hist
nclass	a number of intervals for the histogram
coeff	to fit the magnitude of the graph
sim	a numeric vector of simulated values
obs	a numeric vector of an observed value
call	a call order

Value

as.rtest returns a list of class rtest
plot.rtest draws the simulated values histograms and the position of the observed value
