R – create scatterplot with ggplot2
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…

R – find cases (rows) that match specific criteria
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…

R – delete one or several variables in a dataset
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…

R – create variable filled with zeros
I ran into a situation where I needed to add a variable to a dataset. I knew that I was then going to modify some of the values in the variable, but most of the values were going to be zeros. So, I wanted to create a new variable and fill it with all zeros.…

Unethical Amazon Review Modifications
I don’t always review products on Amazon. I don’t have the time. But there have been two instances over the past year when I have been contacted by someone because of a review I wrote on Amazon.

Linux/Kubuntu – Disable Network Printer Auto Discovery
I don’t know when Kubuntu started automatically discovering printers on networks and then adding them to my list of printers, but it is a problematic feature in certain environments – like universities (where I work). I set up my home printer on my laptop easy enough. But, whenever I open my laptop and connect to…

Linux – Failing to Read Encrypted DVDs
Thanks to the fine folks at VLC and Ubuntu, watching DVDs on Linux is generally pretty straightforward. Install “libdvd-pkg” and follow the prompts and you’re generally good to go. That works for me almost all of the time. However, I recently tried to watch a DVD and had no luck. I would insert the DVD…

Letter to the Editor: Government of the Corporations, by the Corporations, for the Corporations
While accepting “donations” for tens or hundreds of thousands of dollars from lobbyists, corporations, and special interests may technically be legal for Governor DeSantis, there is no question that is unethical. These are “bribes by another name.” And what they suggest is that our Governor is not the Governor of the people of Florida, but…

Letter to Stacy White, County Commissioner
Stacy White, Hillsborough County Commissioner, filed a lawsuit that is preventing Hillsborough County from improving its transportation infrastructure based on a ballot measure that was approved by 57% of voters in November 2018 (more about this here). Here’s the email I recently sent him: Commissioner White, I want to let you know that I’m really…
