Charting the Defeat of AV using R (and some ggplot2 and merge operations on top)

In this post, I’ll be graphing some results from a recent referendum held here in the UK and combining it with the results of a set of local elections that were held at the same time. I’ll give some examples Continue Reading

Is R an ideal language to teach the fundamentals of programming to researchers with no experience in programming?

UPDATE: I’ve modified the title of this post a bit to clarify what I was really thinking when I wrote it. What I was really thinking was which programming language to choose to teach some fellow researchers how to get Continue Reading

Loops, Conditionals and Variables: A Basic Simulation in R

In this post, I’m going to go over some basics of using conditionals and loops in R. I’ll expand on the example I use here in future posts. The conditionals and loops will be used to create some dummy eye Continue Reading

Data Aggregation in R: plyr, sqldf and data.table

I’ve previously put up a couple of posts about aggregating data in R. In this post, I’m going to be trying some other alternative methods for aggregating the dataset. Before I begin, I’d like to thank Matthew Dowle for highlighting these to Continue Reading

Further Adventures in Visualisation with ggplot2

So I previously took a look at some data of player performance from a computer game. In this post, I’m going to do some further visualisations using ggplot2. The data consists of different types of player character, different roles for Continue Reading

Sexy, Geeky Graphs using ggplot2 in R

So I’ve been looking for some data to play with while learning R, other than the data I’m analysing for various experiments and papers I’m working on. I thought to myself, “Hey, this R stuff is pretty geeky. Can I Continue Reading

Aggregate Function in R: Making your life easier, one mean at a time

I previously posted about calculating medians using R. I used tapply to do it, but I’ve since found something that feels easier to use (at least to me). aggregated_output = aggregate(DV ~ IV1 * IV2, data=data_to_aggregate, FUN=median) aggregated_output The above Continue Reading

RStudio, Revolution Analytics and Deducer: A Tale of Three GUIs

I’m in the process of moving from SPSS to R at the moment. It’s not been the easiest of rides, but then learning how to do a core part of your job never really should be. It’s been fun, though Continue Reading
