Getting and Cleaning Data (dyplr, tidr, lubridate) Data cleaning swirl::install_course(“Getting and Cleaning Data”) Statistical inference (probability, distributions, hypothesis testing) probabilities swirl::install_course(“Statistical Inference”) Regression Models regression models swirl::install_course(“Regression Models”) Exploratory […]

Setting up a Zotero workflow on MacOS

Zotero will only allow you to sync your library using either their service (not enough space) or via WebDAV. My Dreamhost backups storage doesn’t support webDAV. I tinkered around with some options (e.g., storagemadeeasy) to turn either my Dreamhost or my NAS shares into WebDAV folders. But, then, I learned that Mac OS doesn’t play […]

Installing R & RStudio

If you have not used or installed R previously, follow the instructions on this page to install R, RStudio, and swirl before the first day of class. Note: If you are a Windows user, you must have an administrative account to install software. We will be using R & RStudio during class and for all […]

Installing and exploring R with swirl

swirl is an interactive learning tool that works inside RStudio. I recommend swirl exercises for all R users, but especially for students who have never used a command script with a software analysis program before. Install the swirl package inside RStudio. You are now ready to install the swirl package in RStudio. A package is […]

Running legacy Win-only software on Mac OS

One of the headaches of moving to Mac has been that I have one piece of statistical software that is Windows only. I could abandon the software and learn R, but I didn’t want to do anything rash. 🙂 Besides, at the Midwest, Fred assured me that he was able to get everything to run […]

Moving on up….

… to Maclandia. We’ve replaced our Linux and Windows pcs with Macbooks. The world is a scary but shiny new place. We also upgraded our NAS to 4 TB. It’s taken me a couple of weekends, but I’ve finally gotten all my files moved, various tools installed, and a full range of backup provisions configured. […]

Christmas stories

I’m sure every family has a collection of stories they share around Christmas. One of the favorites in my mom’s family is about the time, when my mom was in elementary school, her dad told her they weren’t having Christmas so that she would stop bugging them about her presents. He told her they couldn’t […]

Customizing Emacs

I figure one way to become more familiar with Emacs is to customize some of its settings. Of the various pages I’ve found on the web that describe different customizations, I’ve found these two to be the most useful. First, I wandered around the Emacs customization menu by clicking the Customize Setup link on the […]

Follow-up to post about LaTeX, etc.

Yesterday, I provided a rough outline of the steps for installing Emacs + AUCTeX in Windows 7. Upon further reflection, I realized a few things about the process. First, most of the documentation for these tools is outdated and/or poorly written (at least for recent versions of Windows). Second, it’s way easier to install this […]

Installing and learning LaTeX

Long on my to-do list has been to use LaTeX, mainly for its BibTeX features. I’ve avoided it for so long because I’m pretty adept at MSWord. However, with Office2010 and that blasted ribbon, they broke all my keyboard shortcuts for menu items (imagine grumpy old professor shaking hand at the gods and yelling). As […]
