toywin {spagmix}

Toy Windows

Description

Synthetic spatial windows for use in testing, simulations and demonstrations.

Usage

data(bx)
data(heart)
data(shp1)
data(shp2)
data(star)
data(toywin)

Format

Each of these is a single closed polygon of class owin.

• bx is a box on [-5,5]^2.

• heart is a heart, professing love for all things spatstat.

• shp1 is shape of mystery.

• shp2 is a slightly more symmetric shape of mystery.

• star is a star that shines brightly in even non-spatial contexts.

• toywin is the eponymous toy window used in publications e.g. Davies & Lawson (2019).

Details

These are lazy-loaded so may be called directly by name upon loading of spagmix.
