plot.fanovatests function

Plot P-values of Tests Based on Random Projections for FANOVA Problem

The p-values of the tests based on random projections for the one-way analysis of variance for (univariate) functional data against the number of projections are plotted.

## S3 method for class 'fanovatests'
plot(x, y, ...)

Arguments

• x: an "fanovatests" object. More precisely, a result of the function fanova.tests for the standard tests based on random projections.
• y: an "fanovatests" object. More precisely, a result of the function fanova.tests for the permutation tests based on random projections.
• ...: additional arguments not used.

Note

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