I ran into an issue the other day that ended up taking me hours to solve, in part because I couldn’t find any other solutions online, which is pretty unusual these days. Here was the issue: I was evaluating a paper (I’m an academic and read lots of papers) that had a bunch of Greek […]

I added a number of video files to my Plex server the other day and, when I checked Plex, some of them had not shown up in the corresponding library. I tried the obvious solutions. First, I selected the options for the library and then chose “Scan Library Files”: That will often solve the problem, […]

I use Plex to manage my music and video libraries. I actually don’t watch sports very often. The one exception is when I’m grading papers (I’m a college professor). I’ve found that watching soccer/futbol matches in the background while I grade papers breaks up the monotony of grading. With finals coming up, I thought it […]

Let’s say I want to see whether the number of Mormon temples being built aligns with the number of Mormon stakes (akin to a Catholic diocese) that […]

I’m a science fiction fan. And I want my science fiction at my fingertips. To that end, I have slowly been digitizing my favorite series (e.g., Star Trek, Stargate, and now Doctor Who) and putting them on my fileserver that uses Plex to serve the episodes to whatever device I want. I recently ran into […]

R has pretty amazing capabilities for creating charts and graphs. One of the most common packages for this is ggplot2. However, it’s not the most intuitive package I have used in R. So, I figured I’d illustrate how to make some relatively simple scatterplots in R using ggplot2. I’ll likely post instructions on how to […]

I regularly need to find a specific case or set of cases that meet some criteria when analyzing data, often so I can modify those values for one reason or another. The easiest way I have found to find such values in R is the “which” function. As with most of my R examples, I’m […]

I regularly create variables while analyzing data and then find that I need to delete a variable I created. At times, I just want to get rid of a variable in a dataset (’cause screw that variable). This short tutorial will explain how to delete a variable (or multiple variables if needed). As with most […]
