Spatial fuzzy overlay between variables pairwise

Usage

fuzzyoverlay2(formula, data, method = "and")

Arguments

formula: A formula.
data: A data.frame or tibble of discretized data.
method: (optional) Spatial overlay method. One of and, or, intersection. Default is and.

Value

A list

overlay: overlay results between pairs of variables
variable: pairwise interacting variable

Examples

sim = tibble::tibble(y = stats::runif(7,0,10),
                     x1 = c(1,rep(2,3),rep(3,3)),
                     x2 = c(rep(1,2),rep(2,2),rep(3,3)),
                     x3 = c(rep(1,3),rep(2,2),rep(3,2)))
fo1 = fuzzyoverlay2(y ~ .,data = sim, method = 'and')
