krandtest {ade4}R Documentation

Class of the Permutation Tests (in C).

Description

Plot and print many permutation tests. Objects of class 'krandtest' are lists.

Usage

## S3 method for class 'krandtest'
plot(x, mfrow = NULL, nclass = NULL, main.title = x$names, ...)
## S3 method for class 'krandtest'
print(x, ...)
as.krandtest(sim, obs, alter = "greater", call =
match.call(), names = colnames(sim), p.adjust.method = "none")

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

sim

a matrix or data.frame of simulated values (repetitions as rows, number of tests as columns

obs

a numeric vector of observed values for each test

alter

a vector of character specifying the alternative hypothesis for each test. Each element must be one of "greater" (default), "less" or "two-sided". The length must be equal to the length of the vector obs, values are recycled if shorter.

call

a call order

names

a vector of names for tests

p.adjust.method

a string indicating a method for multiple adjustment, see p.adjust.methods for possible choices.

Value

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