krandtest: 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.
