perm.plot: Plot partial p-values

Description

perm.plot plots all of the partial comparison p-values in a matrix.

Usage

perm.plot(p, k, lab = NULL, save = FALSE, name = "pvalues.eps")

Arguments

p

Output of function perm.test, if part = TRUE.

k

Number of groups, must be greater than 2.

lab

Group labels. Defaults to 1, 2, ..., k.

save

Boolean variable that indicates if the plot must be saved as an .eps. Defaults to FALSE.

name

If save is TRUE, this is the filename of the plot. Defaults to pvalues.eps.

Value
