Displaying data using level plots
A level plot is a type of graph that is used to display a surface in two rather than three dimensions – the surface is viewed from above as if we were looking straight down and is an alternative to a contour plot – geographic data is an example of where this type of graph
The new GUI for ggplot2 (using Deducer) – the designer wants your opinion
After discovering that R is expected (this summer) to have a GUI for ggplot2 (through deducer), I later found Ian’s gsoc proposal for this GUI. Since the system is in it’s early stages of development, Ian has invited people to give comments, input and critique on his plans for the project. For your convenience (and with Ian’s permission), I...

Summarising data using box and whisker plots
A box and whisker plot is a type of graphical display that can be used to summarise a set of data based on the five number summary of this data. The summary statistics used to create a box and whisker plot are the median of the data, the lower and upper quartiles (25% and 75%)
Doing Maximum Likelihood Estimation by Hand in R
Lately I’ve been writing maximum likelihood estimation code by hand for some economic models that I’m working with. It’s actually a fairly simple task, so I thought that I would write up the basic approach in case there are readers who haven’t built a generic estimation system before. First, let’s start with a toy example
