r has the sample() function. This function can be used for combinatoric problems and statistical simulation. This allows you to conduct uniform sampling with the chosen sample size, and uses a random number
Section 3.7.2 explains how to run programs in R, and points out that it is important to set R's working directory to the folder in which the programs reside. The R programming language is great at doing Bayesian statistics for a number of reasons. First, it's free! You can get it ...
