R Markdown installation for WISG19 example.

1. In R, install the package "rmarkdown"
2. You will need a LaTex program to generate PDFs from rmarkdown. Follow the general installation instructions in the following URLs (This will take some time)
	Windows: https://miktex.org/download
	Mac: https://tug.org/mactex/mactex-download.html
3. Restart RStudio
4. Open WISG19_Session10_RMarkdown.Rmd
5. Click the "Knit" Button (or the arrow to choose output type)
6. The console will open a new R Markdown tab. If everything is correct, a PDF or HTML document should pop up after everything has run. If not, you will get errors within the R Markdown tab (in bright red font).
