Analysing longitudinal data: Multilevel growth models (I)

Last time we have discussed the two formats of longitudinal data and visualised the individual growth trajectories using an imaginary randomised controlled trial data-set. But could we estimate the overall trajectory of the outcomes along time and see if it’s increasing, decreasing, or stable? Yes, of course, we could estimate that in multilevel growth models

Managing longitudinal data: Conversion between the wide and the long

If you measure the same person twice, you have longitudinal data. We all love longitudinal data because we can understand how their health outcomes change with time and this helps answering many interesting research questions. However, newer R users often face a problem in managing longitudinal data because it often comes in two ‘shapes': the

Rendering LaTeX Math Equations in GitHub Markdown

The Problem: GitHub README.md won't render LaTeX I have many times wondered about getting LaTeX math to render in a README file on GitHub. Apparently, many others ( 1, 2, 3 ), have asked the same question. The common answers are: It cannot (and in some cases, shouldn't) be done. GitHub parsing is done by

RStudio and GitHub

Version control has become essential for me keeping track of projects, as well as collaborating. It allows backup of scripts and easy collaboration on complex projects. RStudio works really well with Git, an open source open source distributed version control system, and GitHub, a web-based Git repository hosting service. I was always forget how to

Line plots of longitudinal summary data in R using ggplot2

I recently had an email for a colleague asking me to make a figure like this in ggplot2 or trellis in R: As I know more about how to do things in ggplot2, I chose to use that package (if it wasn't obvious from the plot or other posts). Starting Point Cookbook R/) has a

Get your R education going with GitHub

by Joseph Rickert Last week, I was fortunate enough to attend the R Summit & Workshop, an invitation only event, held at the Copenhagen Business School. The abstracts for the public talks presented are online and well worth a look. Collectively they provide a snapshot of the state of development of R and the R Community as well some...

Get by with a little (R) help from your friends (at GitHub)

@JennyBryan posted her slides from the 2015 R Summit and they are a must-read for instructors and even general stats/R-folk. She’s one of the foremost experts in R+GitHub and her personal and class workflows provide solid patterns worth emulation. One thing she has mentioned a few times—and included in her R Summit talk—is the idea

Everyone loves R markdown and Github; stories from the R Summit, day two

More excellent talks today! Andrie de Vries of Microsoft kicked off today’s talks with a demo of checkpoint. This is his package for assisting reproducibility by letting you install packages from a specific date. The idea is that a lot of R packages, particularly those from PhD projects don’t get maintained, and suffer bitrot. That

Running RStudio on Digital Ocean, AWS etc Using Tutum and Docker Containers

Via RBloggers I noticed a tutorial today on Setting Rstudio server using Amazon Web Services (AWS). In the post Getting Started With Personal App Containers in the Cloud I described how I linked my tutum account to a Digital Ocean hosting account and then launched a Digital Ocean server. (How to link tutum to Amazon
