R demos for presentation [closed]

Question

I know this is barely programming related, but I'll have to show some intuitive, straightforward and possibly very appealing R presentation so that a department at my current institution will start to evaluate its adoption. Does anyone of you know any R script that shows the power, simplicity and flexibility of R? I'm looking especially for scripts belonging to two categories:

• easy code showing how quick it is to calculate descriptives, basic plots like barchart, boxplots, simple linear regression - all of that concisely and beautifully
• code showing fancy visualizations of complex multivariate datasets (ie. heatmaps etc)

Interactivity for scripts belonging to the second category is a plus.

Of course having data to use with the scripts would also be appreciated ;)

Thanks in advance

Answer 1

Quick-R is a nice site for some examples on how you can easilly do a ton of useful stuff in R:

For fancy visualizations, check out some of the examples from my package qgraph:)

Most of those pictures are included in the help files ( ?qgraph.pca, ?qgraph.efa )

And of course check out examples from ggplot2
