There is also an introduction module, which is available now. It has instructions for downloading and installing the free software that you need for the course.<\/p>\n<p>The instructor is Andrew Ba Tran, a Data Reporter for the Washington Post\u2019s rapid response investigative team.<\/p>\n<p>Why I Signed Up<\/p>\n<p>As I mentioned, I see lots of R tweets in my Twitter feed, so this is a good opportunity to learn a bit about it. Here are a few more reasons why I signed up:<\/p>\n<ul>\n<li>I&#8217;m not a journalist, but the course information page says, &#8220;We welcome anyone interested in quickly <strong>asking questions of and assessing data<\/strong>.&#8221; We do that in Excel too, especially with the new Power BI tools. It sounds like R can build queries, similar to what Power Query does. Learning R might help me work better in Power Query too (I&#8217;m only a beginner in that).<\/li>\n<li>The software is <strong>free and open source<\/strong>, so there&#8217;s no monetary investment \u2013 just my time investment in going through the course modules. After a couple of modules, if I find that it&#8217;s not worth my time, I can un-enroll from the course.<\/li>\n<li>Based on the promo video for the course, the instructor, Andrew Ba Tran, seems <strong>easy to follow<\/strong>. He spoke well, at a good speed, and didn&#8217;t use a bunch of advanced statistical terms, to scared me away.<\/li>\n<\/ul>\n<h3>Replacing Excel<\/h3>\n<p>In the Introduction Module, there are a couple of mentions of using R to replace Excel. I&#8217;m certainly not looking to do that! The instructor says that you &#8220;can&#8217;t reuse things in Excel&#8221;, but R code can be used on multiple data sources. I guess he hasn&#8217;t seen what Power Query can do in Excel.<\/p>\n<p>However, R does seem to have the capacity to create cool charts and maps, without some of the workarounds needed in Excel. Will this course show me ways that R and Excel can work nicely together?<\/p>\n<h3>Getting Ready<\/h3>\n<p>I&#8217;ve gone through the Introduction Module, and that took about and hour and a half. There were clear instructions (video and transcript) for downloading the free software:<\/p>\n<ul>\n<li>R<\/li>\n<li>RStudio<\/li>\n<li>Git<\/li>\n<\/ul>\n<p>It also showed how to use the Command window to add your name and email in Git. I already have a GitHub account, which we also need, I think.<\/p>\n<p>The course syllabus says that we need an API for the US Census Data, so I got that too, even though it wasn&#8217;t mentioned in the Intro Module.<\/p>\n<p>The module has a link to a <a title=\"why journalists should use R\" href=\"https:\/\/flowingdata.com\/2016\/07\/12\/r-in-the-data-journalism-workflow-at-fivethirtyeight\/\" target=\"_blank\" rel=\"nofollow noopener\">video with Andrew Flowers<\/a>, from FiveThirtyEight. He gives 5 reasons why R is helpful in data analysis, and that gave me a good overview of why this course might be helpful to me.<\/p>\n<p><a href=\"https:\/\/debradalgleish.com\/blog\/wp-content\/uploads\/2018\/07\/rcourse02.jpg\"><img loading=\"lazy\" decoding=\"async\" style=\"background-image: none; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-width: 0px;\" title=\"rcourse02\" src=\"https:\/\/debradalgleish.com\/blog\/wp-content\/uploads\/2018\/07\/rcourse02_thumb.jpg\" alt=\"rcourse02\" width=\"427\" height=\"238\" border=\"0\" \/><\/a><\/p>\n<h3>Do You Use R?<\/h3>\n<p>If you&#8217;re an Excel user, do you also use R? If not, have you ever considered learning the basics of how R works? Did you learn it, and decide not to use it?<\/p>\n<p>Finally, if you&#8217;re enrolled in this course, please let me know. I might need to sit beside you, and copy your notes!<\/p>\n<p>___________________<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An announcement for an Introduction to R course arrived in my inbox recently, so I checked it out.
