Line Endings Are Dumb

 Posted on December 20, 2018  |  2 minutes  |  Erin M. Buchanan

I have happily acquired a new Mac Book (yay!) and a new work computer (Windows). So, I’ve been making One Drive exceedingly unhappy moving GBs of file from one to another. As I was working on reconnecting my GitHub repositories to the files, I was trying to understand why several of my repos were saying I had a bunch of file changes but nothing in the files themselves had changed. I noticed they were mostly . [Read More]

Intuitions about Grades

 Posted on December 2, 2018  |  6 minutes  |  Erin M. Buchanan

Are my intuitions about grades correct? I was recently talking to a colleague about how utterly terrible my students were doing in my online class this semester and that nearly half were failing the class. We are in our last week of the semester, and I am completely over packing, so I thought I would examine if the judgments I had made about this semester are accurate. First, I took all the times I had taught memory and cognition post Ph. [Read More]

JASP Videos + Guides

 Posted on October 29, 2018  |  2 minutes  |  Erin M. Buchanan

Hey everybody! I am back and finally getting to videos again. I hesistate to say “it’s been crazy!” because I feel like that’s always a thing that academics say, but I will say I’ve had a lot of life going on, and I am finally getting back to a normal amount of crazy. I’ve decided to do some simple videos to start - so I am creating how-to videos to go with our JASP guides we created this summer. [Read More]

Quick and Dirty Categorical lavaan

 Posted on July 5, 2018  |  4 minutes  |  Erin M. Buchanan

I was tagged today on twitter asking about categorical variables in lavaan. I will say I have not done much with categorical predictors either endogenous or exogenous. I did a quick reproducible example of exogenous variables, and I will refer you to the help guide for lavaan here. You will need both the lavaan and psych packages to reproduce this code. Ironically, this data is binary outcome data (the epi dataset in psych), which wasn’t intentional, I just knew it was a good dataset to work with to test how to do exogenous categorical variables.

Current Publications with Papaja

 Posted on May 21, 2018  |  2 minutes  |  Erin M. Buchanan

Heyo! Frederik, the author of papaja, requested that we update him with papers written with his package. I was like, oh man, like the whole lab?! So, I decided that I could probably make it easy by making a table here. Obviously, this table is current at the moment, as I hope many of the ones under review will get accepted, and I have several others that we will start writing soon. [Read More]

Gathering Text from the Web

 Posted on May 7, 2018  |  6 minutes  |  Erin M. Buchanan

Hi everyone! I don’t really feel like working too hard today, so I decided to write a blog post about how my student Will and I used rvest to mine articles from several different news sources for a project. All the scripts and current ongoings of this project can be found on our OSF page - this project is also connected to the GitHub folder with the files. First, we picked four web sources to scrape - The New York Times, NPR, Fox News, and Breitbart because of their known political associations, and specifically, we focused on their political sections.

Working With Messy Text

 Posted on March 6, 2018  |  6 minutes  |  Erin Buchanan

Heyo! I am doing my best to procrastinate here on a blustery Tuesday afternoon. So, I decided to share some code I’ve put together that solves problems in R that I used to do in perl. HTML or C++ was probably my first real language, but I love the heck out of perl. It’s never done me wrong (unlike you PHP). Anyways! The context of this project is that we are developing a dictionary of words to complement the work done by Jonathan Haidt and Jesse Graham - learn more. [Read More]
