200 Countries animation revisited
Here’s a new animated graph, again made using only stats software – R this time – to recreate Hans Rosling’s famous 200 Countries animation. Have you ever noticed how Prof Rosling had a team of graphics people beavering away in that warehouse to make his video work? Well, I don’t have such a team at my disposal, and I guess neither do ...

Use little images as the markers in a scatterplot
Just saw this post on R-bloggers which has got me excited. I’ve thought about this many times but never looked into it so I can’t honestly say whether this is the first stats software option to do this, despite my occasional throw-away statement to students that they could use little icons as markers.

Reverse engineering the SAS data file format
I think it’s rather marvellous that a few expert coders are working on dispelling the cloud of mystery around the proprietary file format used by SAS software. Essentially, saving your data in a SAS format (with a name like mydata.sas7bdat) locks you into their software. They have tied this up much tighter than the other software houses: IBM ha...

Exporting data from R into WinBUGS’s “R/S-plus list format”
Users of the world’s favourite Bayesian analysis software WinBUGS will recognise the strange format in which data is supplied inside the GUI, generally in a text file looking something like this: list(x=c(1,2,3,4,5,6),y=c(4,8,2,6,9,9)) This is of course an R (or strictly speaking, S) language format, but it’s not how R views data, and althoug...
