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.

Hi guys! I just wanted to post that I’ve updated the website to be current with some new publications I wanted to highlight: First up is two papers on psycholinguistics that were undergraduate student projects: Duncan, J., Buchanan, E.M., Marshall, C.Z., & Oberdieck, K. (accepted). But words will never hurt me, Journal of Psychology and Behavioral Sciences, X, XX-XX. PDF Forbes, F.-J., & Buchanan, E. M. (accepted). “Textisms”: The Comfort of the Recipient, Psychology of Popular Media Culture, X, XX-XX. [Read More]

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]

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.

One more announcement! We just had a new publication accepted: “Textisms”: The Comfort of the Recipient: This paper was an undergraduate honors thesis that Flora-Jean and I finally got accepted! She did a great job making sure this paper was completed and published. You can check out the materials here: https://osf.io/8kt52/ You can view the pre-print: https://osf.io/ptf7c/ We should have the real print up soon! Just waiting on the journal now. [Read More]

Hi everyone! I have been super swamped with a bunch of due dates that all hit in April. For a small brag, and I like making lists: 9 revise and resubmits (four we’ve sent back, two have been accepted!) 4 conference posters and one invited talk 1 submitted grant (fingers crossed!) 2 invited papers 2 theses that I’m chairing, 2 that I’m on the committee for Data camp! It’s been nuts, so haven’t left the house much or done much of anything else. [Read More]

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]

Just wanted to do a quick post to say that the Nature Human Behavior response paper, Justify Your Alpha is now online at NHB’s website: Springer - it is free to view but not download. You can download the PDF version on OSF. We’ve submitted a couple new papers as well - updated those on my research publications page. I also have a couple more to get done - hoping to feature some of the cool coding work I’ve done this week after taking a breather from a seriously packed week. [Read More]

My coauthor John Scofield and I just had a publication accepted at Behavior Research Methods - you can check out the publication preprint at OSF. We thew together a website for the paper that summarizes everything we found, as well as puts all the materials together in one place - check it out. We create a really nice R function to help you detect low quality data, which you can find on GitHub, and I even made a video that explains all the parts to the function at YouTube. [Read More]

Heyo! I wanted to write a post about some of the quirky things I’ve found with writing manuscripts in R Markdown, as well as provide a solution to a problem that someone else might be having. Update: The csl file I describe below is a special formatted one, which was shared with me. You can download it from GitHub to try the suggestions below. Update 2: Turns out, potentially, the suggestions from the manual are not working correctly, as Frederik has checked it out and opened an issue on github. [Read More]
