[R] applying operations within() a matrix's environment

I am trying to optimize code for speed and readability for a fairly complex function inside an MCMC sampler. As of now I have a bunch of variables inside a function that get iteratively reset inside a loop. Something like this: set.seed(1) K <- 10 v1 <- rnorm(K) v2 <- rnorm(K) v3 <- rnorm(K) ste
