plot.gp {spectralGP}

Plot a process based on a spectral GP object

Description

Makes a line plot (for one-dimensional processes) or image plot (two-dimensional processes) of a process represented in a spectral GP object.

Usage

## S3 method for class 'gp'
plot(x, type = "l", col = terrain.colors(32), ...)

Arguments

x

A GP object, created by gp.

type

Type of plot if process is one-dimensional, "l" for line, "p" for points, etc.

col

Color scheme for image plot if process is two-dimensional. E.g., topo.colors(64) is the default for image_plot; I prefer terrain.colors(64) as topo.colors has sharp color changes between adjacent bins.

...

Extra arguments to plotting functions.

Value

No value is returned.
