<p>A new release, now at version 0.6.12, of the <a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/code/digest.html">digest</a> package is now on <a target="_blank" rel="nofollow" href="http://cran.r-project.org/">CRAN</a> and in <a target="_blank" rel="nofollow" href="http://www.debian.org/">Debian</a>.</p>
<p>The <a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/code/digest.html">digest</a> creates hash digests of arbitrary R objects (using the ‘md5’, ‘sha-1’, ‘sha-256’, ‘crc32’, ‘xxhash’ and ‘murmurhash’ algorithms) permitting easy comparison of R language objects.</p>
<p>This release extends sha1 digest methods to even more types, thanks to another contribution by Thierry Onkelinx.</p>
<p><a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/cranberries/index.html">CRANberries</a> provides the usual summary of changes to the <a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/cranberries/2017/01/27#digest_0.6.12">previous version</a>.</p>

<p>In two weeks, the third year of the <strong>Data Science for Actuaries</strong> program will start. I will be there for the introduction to R. The slides are available <a target="_blank" rel="nofollow" href="http://freakonometrics.free.fr/DSA2017/DSAslides.html">online</a> (created with <a target="_blank" rel="nofollow" href="http://slidify.org/">slidify</a>)</p>

<p>A <a target="_blank" rel="nofollow" href="http://freakonometrics.free.fr/DSA2017M/DSAmark.html">markdown</a> is also available. I have to thank <a target="_blank" rel="nofollow" href="http://egallic.fr/">Ewen</a> for his help on slidify (especially for the online quizz, and the integration of leaflet maps or the rgl animated graph….)</p>

<p>Imagine that in the course of your analysis, you regularly require summaries of numerical values. For some applications you want the mean of that quantity, plus/minus a standard deviation; for other applications you want the median, and perhaps an interval around the median based on the interquartile range (IQR). In either case, you may want the summary broken down with respect to groupings in the data. In other words, you want a table of values, something like this:</p>
<pre>
dist_intervals(iris, &quot;Sepal.Length&quot;, &quot;Species&quot;)

# A tibble: 3 × 7
     Species  sdlower  mean  sdupper iqrlower median iqrupper

<p>The ASA (American Statistical Association) has been working in collaboration with the ACM (Association for Computing Machinery) on developing a data science curriculum for Two Year Colleges. Part of this development is the need to understand the private-sector demand for two-year college data science graduates and the prevalence of the need to invest in the continuing education of existing employees for gap-filling critical skills shortages in “knowledge workers”.</p>
<p>By taking <a target="_blank" rel="nofollow" href="https://www.surveymonkey.com/r/PVFPLDZ">this survey</a>, participating in a workshop/summit or — especially — submitting a <a target="_blank" rel="nofollow" href="https://www.nsf.gov/pubs/policydocs/pappguide/nsf16001/gpg_2.jsp#IIC2j">letter of collaboration</a> you will be helping to prepare your organization and our combined workforce meet the challenges of succeeding in an increasingly data-driven world.</p>
