In week 3 we had an impromptu session about R markdown which is the document format being used for in class exercises.
Before attempting to use R markdown you should ensure you have installed an up to date version of R https://cran.ms.unimelb.edu.au/ and an up to date version of RStudio (see https://www.rstudio.com/products/rstudio/download/)
A good place to start learning about R markdown is the official website at http://rmarkdown.rstudio.com. This section on R markdown in Hadley Wickam’s R for Data Science book may also be helpful.
In class we have seen examples of using R markdown to produce static html documents. Some other examples have been added to the down menu for week 03 on the website. The files that can be viewed on the website were all created using R markdown. The source R markdown files (i.e., files ending in .Rmd) can be viewed and downloaded from the github repository where the website files are stored.
