plot.mrfi {mrf2d}

Plotting of mrfi objects.

Description

Plots a visual representation of the interaction structure described in a mrfi object. The black tile represents a reference pixel and gray tiles are shown in relative positions with dependent pixels.

A ggplot object is used, therefore, the user can load the ggplot2 package and add more ggplot layers to freely customize the plot.

Usage

## S3 method for class 'mrfi'
plot(x, include_axis = FALSE, include_opposite = TRUE, ...)

include_opposite

...

other arguments not used by this method.
