When converting R Markdown to PDF, we can use a lot of variables for the LaTeX template. This short example shows the classoption variable that takes the value landscape to produce PDF in the landscape orientation.

str(cars)

## 'data.frame':    50 obs. of  2 variables:
##  $ speed: num  4 4 7 7 8 9 10 10 10 11 ...
