krandtest {ade4} | R Documentation

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

### Description

Plot and print many permutation tests. Objects of class `'krandtest'` are data frame with n+1 rows and p columns.
Each column corresponds to a permutation test : the first value is the observed-value and the n others are the simulated ones.

### Usage

    plot.krandtest(x, mfrow = NULL, nclass = NULL, main.title = names(x), ...)
    print.krandtest(x, ...)

### Arguments

`x` | : an object of class `'krandtest'`
`mfrow` | : a vector of the form 'c(nr,nc)', otherwise computed by as special own function `n2mfrow`
`nclass` | : a number of intervals for the histogram
`main.title` | : a string of character for the main title
`...` | : further arguments passed to or from other methods

### Value

`plot.krandtest` draws the p simulated values histograms and the position of the observed value.

### See Also

`randtest`

### Examples

    wkrandtest <- data.frame(eg1=c(0, rnorm(200)))
    for (x0 in c(1.2,2.4,3.4,5.4,20.4)) {
        wkrandtest <- cbind.data.frame(wkrandtest, c(x0, rnorm(200)))
    }
    names(wkrandtest) <- paste ("Test",1:6,sep="_")
    class(wkrandtest) <- "krandtest"
    wkrandtest
    plot(wkrandtest)
