In caspr: Cellular Automata for Spatial Pressure in R

Description Usage Arguments Details Value

Create vector maps for cellular automata updating.

1 2	mapping(width, height = width, boundary = "periodic", i_matrix = matrix(c(0, 1, 0, 1, NA, 1, 0, 1, 0), ncol = 3, byrow = TRUE))

`width`	An integer number giving the width of the landscape or a landscape object.
`height`	An integer number. The height of the landscape. Defaults to value given in width.
`boundary`	A character value representing the type of boundary conditions. Defaults to `"periodic"`. No other boundaries implemented, yet.
`i_matrix`	A matrix defining the interaction matrix to be evaluated. Defaults to 4-cell neighborhood.

This function and the objects generated by it are necessary for the function neighbors to vectorise the calculation of neighbors. The interaction matrix can be flexibly defined as a matrix that has precisely one cell with value NA, marking the focal cell. Any number larger than 0 marks a cell that is to be taken into account for counting.

Creates a map of the landscape object to translate it into a vector with boundaries (x_with_border) and another one to back-translate it to a vector without boundaries (x_to_evaluate) into the global environment. This will automatically be called within ca().
