The Codecogs website provides an Open-source library of functions for numerical analysis. One interesting component available on the website is the LaTeX equation editor which can be used to create graphics files of equations to include on webpages.

The webpage describe this component as a A web-based LaTeX equation editor that generates graphical images and HTML code to embed any equation into any website, forum or blog. This editor could be used in conjunction with powerpoint to include equations that look more professional than using the built in equation editor.

There are many blogs on Statistics, R and other related topics scattered around the internet. The R bloggers website provides a central hub where feeds from participating blogs are collated so that they can be viewed from a single website.

This resources certainly appears to be a good idea so that people can more easily identify blogs with information about the use of the R statistical software system.

The grammar of graphics approach to constructing graphs has been implemented in the ggplot2 package in R. The author of the package, Hadley Wickham, has provided a website with many details of using the system to create nice looking graphics.

The package removes many of the awkward parts of setting up graphical display that characterise other approaches in R.

The R environment for Statistical Analysis has strong facilities for producing high quality graphical output. There are many books and electronic documents that demonstrate examples of effective ways to display data graphically. To get an feel for the range of display that could be used it is worthwhile visiting the R Graph Gallery.

The examples on this website use both the base and lattice graphics functions.
