dichot: Dichotomize data with a cutoff

Description

Function to dichotomize the input data for the semigroup construction with a cutoff value.

Usage

dichot(x, c = 1, diag.incl = TRUE)

Arguments

x

some data in a numeric form (usually arrays)

c

the cutoff value to perform the dichotomization (default 1)

diag.incl

(logical) whether or not the diagonals should be included (default TRUE)

Value

Binary values of the input data.

Details

This is a convenient function (or wrapper if you like) of the replace function. In this case the function is aimed to specify a cutoff value for the dichotomization of the data where the values equal or higher to the cutoff are converted to one, while the others are set to zero. The cutoff can be any real number.

Examples

## Create the data: 2 binary relations among 3 elements
arr <- round( replace( array(runif(18), c(3,3,2)), array(runif(18),
       c(3,3,2))>.5, 3 ) )

## dichotomize it with a cutoff value of 2
dichot(arr, c = 2)
