plot.fmanovatrp: Plot P-values of Tests Based on Random Projections for...

In fdANOVA: Analysis of Variance for Univariate and Multivariate Functional Data

Description

The p-values of the tests based on random projections for multivariate analysis of variance for functional data against the number of projections are plotted.

Usage

## S3 method for class 'fmanovatrp'
plot(x, y, withoutRoy = FALSE, ...)

Arguments

x	an "fmanovatrp" object. More precisely, a result of the function fmanova.trp for the standard tests based on random projections.
y	an "fmanovatrp" object. More precisely, a result of the function fmanova.trp for the permutation tests based on random projections.
withoutRoy	a logical indicating whether to plot the p-values of the Rp test.
...	additional arguments not used.

Note

We can use only one of the arguments x and y, or both simultaneously.
