formr Round 3: No nginx Required

 Posted on October 25, 2020  |  7 minutes  |  Erin M. Buchanan

Alright folks! I am back with more installation guides. I’ve installed formr so many times at this point … since my first post, opencpu has updated to R 4+, and I’ve found a way to not use nginx. Which is good news, since it often conflicts with also running apache. I’m going to leave the old guides up because maybe they can help someone figure out their issues, but here goes with the newest guide. [Read More]

Installing RStudio Server + Updates

 Posted on August 30, 2020  |  2 minutes  |  Erin M. Buchanan

One of the most difficult things I try to teach my students is how to deal with error messages. Due to Hurricane Laura, I am currently re-creating several projects including formr, RStudio, and a website. I thought I would detail that here. You can find my first post on formr here: https://www.aggieerin.com/post/formr-installation-instructions/ Good news! It’s mostly the same and pretty smooth. However, I sometimes get this nonsense: installation of package ‘psych’ had non-zero exit status - any time you get the non-zero exit status message, it requires a careful look at the installation messages.

formr Installation Instructions

 Posted on March 31, 2020  |  10 minutes  |  Erin M. Buchanan

An installation guide taken from formr documentation and modified to include more details for those who need it. These installation instructions are provided for Ubuntu 18.04; however, they could be modified for other systems. The original instructions suggest Debian 9, but I found this much easier on Ubuntu. I have now used both Digital Ocean and Amazon Lightsail for this installation. I don’t think the product matters, but the size of the machine is likely something you should focus on. [Read More]

Is English Kurtotic?

 Posted on February 7, 2020  |  6 minutes  |  Erin M. Buchanan

You ever have a random text that sent your brain to work? Here’s mine today: KD Text Followed up with examples that lol is bimodal, while loop is positively skewed, and enter is “almost normal”. The lovely K.D. posed this question to me earlier, and I already have procrastinated a lot today, so here’s to more! First, I typed out some fonts in Word to help me figure out how to code the two important parts for this question: width and height. [Read More]

Lasso Myself Numbers

 Posted on January 21, 2020  |  15 minutes  |  Erin M. Buchanan

Hey everybody! The last couple days I have been trying to learn LASSO regression, which stands for Least Absolute Shrinkage and Selection Operator. I have several datasets with many variables, and I thought these would be a good opportunity to learn about how to lasso, while maybe answering a few questions about words. Right, the part I forgot about is that I have repeated measures data, which always complicates things. [Read More]

The Year of the Thesis

 Posted on December 5, 2019  |  1 minutes  |  Erin M. Buchanan

The Year of the Thesis! Just wanted to highlight several publications from this year, which were mostly theses from some fabulous young researchers: Scofield, J.E., Kostic, B., & Buchanan, E.M. (2019). How the presence of others affects desirability judgments in heterosexual and homosexual participants. Archives of Sexual Behavior, X, XX–XX. doi: 10.1007/s10508-019-01516-w Maxwell, N.P. & Buchanan, E.M. (2019). Investigating the interaction of direct and indirect relation on memory judgments and retrieval. [Read More]

Getting Translations with rvest and Selenium

 Posted on October 7, 2019  |  4 minutes  |  Erin Buchanan

In this guide, I’ll go over how you can use web scraping rvest and Selenium to get translations from Google Translate. Note: I encourage responsible scraping - I always try to do it with some space between requests. You can only do 5000 characters at a time with the free Google translate. I will say that I tried to do this with just rvest and the predictability of the links for Google translate - but I could not get rvest to pull the right data off the page, so here’s a slightly more difficult approach that appears to work.

New Publications

 Posted on October 6, 2019  |  3 minutes  |  Erin Buchanan

Just updated my CV - here’s a few new publications and conferences! The weird thing about the automatic CV updater I wrote is that you can’t really predict what order the same year publications are going to be in - not that it matters in general, but it’s an interesting side effect. Also, super proud - both of these are student theses turned papers: Maxwell, N.P. & Buchanan, E.M. (2019).Investigating the interaction of direct and in-direct relation on memory judgments and retrieval. [Read More]

Multilevel Modeling Workshop Materials

 Posted on May 15, 2019  |  2 minutes  |  Erin M. Buchanan

Many thanks to Rutgers University Spanish and Portuguese Department (https://span-port.rutgers.edu/) for asking me to come talk about multilevel models. I enjoyed talking to the group, meeting Twitter friends in real life!, and I am especially impressed by what their department is doing in what is often considered a qualitative science. I used RStudio’s Cloud to share a workspace with all the materials, packages, and other information you might need. I built the slide show using markdown, so that people could watch the slides and/or take their own notes. [Read More]

Updating Your CV with Packages

 Posted on April 3, 2019  |  9 minutes  |  Erin Buchanan

Hi guys! I have finally done it! I updated my CV with Rmarkdown using Steve’s Markdown Templates. I was tempted to use the new vitae package, but I had already gone down this path before that came out, just finally getting back to it. Link to the entire CV folder for you to use/view do stuff with: CV. Please ignore the html files in that folder, it does “knit” automatically as part of the website build using markdown - you should be using PDF and LaTex for the CV part. [Read More]
