Demonstration Example of Hyperframe of Spatial Data

Description

This is an artificially constructed example of a hyperframe of spatial data. The data could have been obtained from an experiment in which there are two groups of experimental units, the response from each unit is a point pattern Points, and for each unit there is explanatory data in the form of a pixel image Image.

Usage

data(demohyper)

Format

A hyperframe with 3 rows and 3 columns:

Points: List of spatial point patterns (objects of class "ppp") serving as the responses in an experiment.
Image: List of images (objects of class "im") serving as explanatory variables.
Group: Factor with two levels a and b serving as an explanatory variable.

Examples

  if(require(spatstat.model)) {
 plot(demohyper, quote({ plot(Image, main=""); plot(Points, add=TRUE) }),
      parargs=list(mar=rep(1,4)))
 mppm(Points ~ Group/Image, data=demohyper)
  }
