This is a short tutorial on knitr/markdown and JS visualization packages googleVis
You need to have the following R packages and their dependencies installed:
- rCharts (not on CRAN)
The tutorial is organized in four parts. First two parts introduce basics about knitr and markdown. The last parts are about using googleVis and rCharts packages in markdown documents. However, the tutorial does not have in depth examples that show all the capabilities of rCharts and googleVis.
You can download the .Rmd files (or clone the repository from github) and run knit2html() on them in your R console, or if you are using RStudio you can click “knit HTML” button on the upper left corner. The best way to go through the tutorial is to examine the code chunks and explanations in .Rmd files, and then check the HTML output from knit2html().
