spatstat.data (version 3.1-8)

simba: Simulated data from a two-group experiment with replication within each group.

Description

The simba dataset contains simulated data from an experiment with a `control' group and a `treatment' group, each group containing 5 experimental units.

The responses in the experiment are point patterns.

The responses in the control group are independent realisations of a Poisson point process with intensity 80.

The responses in the treatment group are independent realisations of a Strauss process with activity parameter \(\beta=100\), interaction parameter \(\gamma=0.5\) and interaction radius \(R=0.07\) in the unit square.

Usage

data(simba)

Format

simba is a hyperframe with 10 rows, and columns named:

• Points containing the point patterns

• group factor identifying the experimental group, with levels control and treatment).

Examples

   if(require(spatstat.geom)) {
     plot(simba, main.panel=simba$group)
   }
