Creates a window for a PPP object

This function creates a window for a `spatstat::ppp` object, the type of window can be specified using the `window` argument.

Usage

makeWindow(data, window = "square", window.length = NULL)

Arguments

data

A single image data frame from a SingleCellExperiment object or PPP object.

window

The shape of window around the regions, can be `square`, `convex` or `concave`

window.length

A tuning parameter for controlling the level of concavity when estimating concave windows.

Value

Creates an `owin` class, representing the observation window for the image.

Examples

data <- data.frame(x = rnorm(10), y = rnorm(10))
ow <- makeWindow(data, window = "square")

spatstat.geom::ppp(x = data$x, y = data$y, window = ow)
#> Planar point pattern: 10 points
#> window: rectangle = [-1.3187779, 0.7669156] x [-2.2423765, 2.051987] units
