`plot`

method for class "`ITPaov`

".
Plotting function creating a graphical output of the ITP for the test on a functional analysis of variance: functional data, and ITP-adjusted p-values of the F-tests on the whole model and on each factor are plotted.

No value returned.
The function produces a graphical output of the ITP results: the plot of the functional data, functional regression coefficients, and ITP-adjusted p-values of the F-tests on the whole model and on each factor.
The basis components selected as significant by the tests at level `alpha1`

and `alpha2`

are highlighted in the plot of the corrected p-values and in the one of functional data by gray areas (light and dark gray, respectively).
The first plot reports the gray areas corresponding to a significant F-test on the whole model. The remaining plots report the gray areas corresponding to significant F-tests on each factor (with colors corresponding to the levels of the factor).
