Good grief. I am building a new server for PSA research projects, so I thought I would share the latest updates and installs for those who want it for their own use. I will also note that the formr dudes recommend docker installation as shown here: https://github.com/rubenarslan/formr_dev_docker. My luck with docker is so-so, so here’s my guide for manual install. Further, their warning about “no production” makes me quite nervous. https://doomlab.github.io/post/formr-round-3-no-nginx-required/ Sun, 25 Oct 2020 00:00:00 +0000 https://doomlab.github.io/post/formr-round-3-no-nginx-required/ 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. https://doomlab.github.io/post/installing-rstudio-server-updates/ Sun, 30 Aug 2020 00:00:00 +0000 https://doomlab.github.io/post/installing-rstudio-server-updates/ 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. https://doomlab.github.io/post/formr-installation-instructions/ Tue, 31 Mar 2020 00:00:00 +0000 https://doomlab.github.io/post/formr-installation-instructions/ 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. https://doomlab.github.io/post/lasso-myself-numbers/ Tue, 21 Jan 2020 00:00:00 +0000 https://doomlab.github.io/post/lasso-myself-numbers/ 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. https://doomlab.github.io/post/getting-translations-with-rvest-and-selenium/ Mon, 07 Oct 2019 00:00:00 +0000 https://doomlab.github.io/post/getting-translations-with-rvest-and-selenium/ 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. https://doomlab.github.io/post/updating-your-cv-with-packages/ Wed, 03 Apr 2019 00:00:00 +0000 https://doomlab.github.io/post/updating-your-cv-with-packages/ 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. https://doomlab.github.io/post/jasp-videos-guides/ Mon, 29 Oct 2018 00:00:00 +0000 https://doomlab.github.io/post/jasp-videos-guides/ 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.
