R Project

Iris flower data from Edgar Anderson

The “R Project”:http://www.r-project.org/ provides the R ’statistical environment’ – a command driven statistical calculator with considerable graphics capability and plenty of routines. The ‘commands’ are actually part of a full programming language for doing statistics so entire applications can be built within the environment.

The R software is Open Source (capital OS) and pre-compiled binaries can be downloaded for Mac OS X, Windows and various flavours of Linux. I have downloaded all 40Mb of the Mac OS .dmg version so I can create some effective graphs and charts.

* “The back to back histograms”:http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=136 are quite handy for gender comparisons and population age structure graphs
