1 Overview. R provides a variety of functionality for parallelization, including threaded operations (linear algebra), parallel for loops and lapply-type statements, and parallelization across multiple machines. This material focuses on R’s future package, a flexible and powerful approach to parallelization in R.4 should become 2. 5 should become 1. The easiest way to do this is to take the max possible score (5) and add 1 to get 6. Then subtract the original scores from 6 to get the reverse scored value. For example: 5 becomes: 6 – 5 = 1. 4 becomes: 6 – 4 = 2. 3 becomes: 6 – 3 = 3. 2 becomes: 6 – 2 = 4.The R output indicates that the test is now performed on the lowest value (see alternative hypothesis: lowest value -2.6564554 is an outlier). The p-value is 0.998. At the 5% significance level, we do not reject the hypothesis that the lowest value -2.66 is not an outlier. In other words, we cannot conlude that the lowest value -2.66 is an outlier.A code of ethics is necessary because it allows individuals to know what is expected of them as acceptable behavior.
