I have enjoyed the transition back into the academic world, including a more flexible schedule, variation in topics/duties, and collaborating with colleagues.However, there has been some growing pains, especially regarding creating...

## A slightly different introduction to R, part V: plotting and simulating linear models

November 11, 2013

In the last episode (which was quite some time ago) we looked into comparisons of means with linear models. This time, let’s visualise some linear models with ggplot2, and practice another useful R skill, namely how to simulate data from known models. While doing this, we’ll learn some more about the layered structure of a

It’s pretty much the same material as before — data frames, linear models and some plots with ggplot2 — but I’ve sprinkled in some more exercises during the seminars. I’ve tried emphasising scripting a

The bear package is menu driven, which is not my thing. I had to try and do that in R via other packages. The aim is to estimate if the...
