<p>by Joseph Rickert</p>
<p>Last month, 217 new packages were submitted to CRAN. By <a target="_blank" rel="nofollow" href="https://www.rstudio.com/rviews/2017/01/06/10000-cran-packages/">my count</a> this was the highest monthly value recorded for the past nine years. Below, are brief descriptions of fifty-two of these new-for-December packages grouped into six categories: Data, Data Science, Financial Analysis, Statistics, Utilities and Visualizations. The Financial Analysis category is noteworthy. It is unusual to have six interesting packages centered on some financial application in a given month. </p>
<p>It is also unusual for me to be able to identify a favorite package. However, this month I am comfortable pointing out <a target="_blank" rel="nofollow" href="https://cran.rstudio.com/web/packages/deconvolveR/">deconvolveR</a> from Bradley Efron and Balasubramanian Narasimhan which implements Empirical Bayes methods for learning prior distributions from data. I expect that this package will become important to many Bayesian and “Almost Bayesian” statisticians.</p>
