In abichat/correlationtree: Functions about correlation tree

Description

Convert a similarity matrix into a distance matrix.

Usage

sim2dist(sim, transformation = "1-x")

Arguments

sim	a similarity matrix of class "matrix" or "dist".
transformation	function or character. Transformation to apply to each element of the matrix.

Value

sim2dist returns an object of the same class as the input sim.

Examples

n <- 4
mat <- matrix(runif(n^2,-1, 1), ncol = n)
sim <- (mat + t(mat)) / 2
diag <- n * (seq_len(n) - 1) + seq_len(n)
sim[diag] <- 1
sim2dist(sim)
sim2dist(as.dist(sim), transformation = "1-absx")
