spatial fuzzy overlay

Usage

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

Arguments

formula: A formula of spatial fuzzy overlay.
data: A data.frame or tibble of discretized data.
method: (optional) Overlay methods. When method is and, use min to do fuzzy overlay; and when method is or,use max to do fuzzy overlay. Default is and.

Value

A numeric vector.

Note

Independent variables in the data provided to fuzzyoverlay() must be discretized variables, and dependent variable are continuous 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)))
fo1 = fuzzyoverlay(y~x1+x2,data = sim, method = 'and')
fo1
#>      1      2      3      4      5      6      7 
#> "x2_1" "x1_2" "x1_2" "x1_2" "x1_3" "x1_3" "x1_3" 
fo2 = fuzzyoverlay(y~x1+x2,data = sim, method = 'or')
fo2
#>      1      2      3      4      5      6      7 
#> "x1_1" "x2_1" "x2_2" "x2_2" "x1_3" "x1_3" "x1_3"
