swap_cc: Swaps values in each row

In simonsays1980/finmix: An R package for Bayesian estimation of finite mixture distributions

Description

This function swaps the values in each row of a matrix by permuting the columns via the indices provided in the index matrix. All swapElements()-methods use this function internally. The code is extended to C++ using the packages Rcpp and RcppArmadillo.

Usage

swap_cc(values, index)

Arguments

values	A matrix containing the values to be swapped.
index	An integer matrix defining how values should be swapped.

Value

A matrix with swapped values.

Examples

values <- matrix(rnorm(10), ncol = 2)
index <- matrix(c(2,1), nrow = 5, ncol = 2)
swap_cc(values, index)
