plot.simulate.fgpm: Plot method for the simulations of a 'fgpm' model

In funGp: Gaussian Process Models for Scalar and Functional Inputs

Plot method for the simulations of a fgpm model

Description

This method displays the simulated output values delivered by a funGp Gaussian process model.

Usage

## S3 method for class 'simulate.fgpm'
plot(x, y = NULL, detail = NA, ...)

Arguments

x	An object with S3 class simulate.fgpm as created by simulate,fgpm-method.
y	Not used.
detail	An optional character string specifying the data elements that should be included in the plot, to be chosen between "light" and "full". A light plot will include only the simulated values, while a full plot will also include the predicted mean and confidence bands at the simulation points. This argument will only be used if full simulations (including the mean and confidence bands) are provided, otherwise it will be ignored. See simulate,fgpm-method for more details on the generation of light and full simulations.
...	Additional arguments affecting the display. The following typical graphics parameters are valid entries: xlim, ylim, xlab, ylab, main. The boolean argument legends can also be included in any of the two lists in order to control the display of legends in the corresponding plot.
