## 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

## Pivot Tables and Medians in R

Pivot Tables are a useful way of aggregating data into the format that you’re after. In this example, I’m going to be using R to pivot some data and calculate medians for me. This is useful because Excel can calculate Continue Reading
