randtest {ade4} | R Documentation

## Class of the Permutation Tests (in C).

### Description

randtest is a generic function. It proposes methods for the following objects `between`, `discrimin`, `coinertia` `...`

### Usage

        randtest(xtest, ...)
        plot.randtest(x, nclass = 10, coeff = 1, ...)
        as.randtest (sim, obs, call = match.call())
        print.randtest (x, ...)

### Arguments

`xtest` | an object used to select a method
`x` | an object of class `randtest`
`...` | `...` 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.randtest` returns a list of class `randtest`
`plot.randtest` draws the simulated values histograms and the position of the observed value

mantel.randtest, procuste.randtest, rtest

### Examples

    par(mfrow = c(2,2))
    for (x0 in c(2.4,3.4,5.4,20.4)) {
        l0 <- as.randtest(sim = rnorm(200), obs = x0)
        print(l0)
        plot(l0,main=paste("p.value = ", round(l0$pvalue, dig = 5)))
    }
    par(mfrow = c(1,1))
