simForm: Spatial simulation

In bozenne/lava.penalty: Penalized Latent Variable Models

Description

Simulate a geometrical figure on a 2D spatial field

Usage

simForm(n.obs, xmax, ymax, radius, center = NULL, coords.centered = TRUE,
  distance = "euclidean")

Arguments

n.obs	the number of repetitions.
xmax	the length of the spatial field.
ymax	the width of the spatial field
radius	the maximum distance to the center for which pixels will set to 1. The others will be set to 0.
center	the position relative to which the distance will be computed.
coords.centered	should the coordinates be centered around 0,0? Else they will start at 0,0 and take positve values. May affect the computation of the distance.
distance	the type of distance to be used.

Details

The available distances are those of the dist function from the stats package.

Value

a list containing:

• "coords" the coordinates of each point on the field

• "center" the center used to compute the distance

• "distCenter" the distance of each point to the center

• "X" the distance thresholded by the radius

Examples

image(simForm(100, 10, 10, 2)$X)
image(simForm(100, 10, 10, 2, distance = "maximum")$X)
