Suppose we want to display Presidential Approval, where the first column provides overall approval and subsequent columns are crosstabs for various factors of interest (using the cell weights). (setwd isn’t needed in the Rmd, but setting the working directory separately in Console is recommended if you’re still editing.). Here is a basic plot we might want, which reflects the survey weights. When you run render, R Markdown feeds the .Rmd file to knitr, which executes all of the code chunks and creates a new markdown (.md) document which includes the code and its output. Please note that I have no affiliation (past or present) with Pew Research.

Use a productive notebook interface to weave together narrative text and code to produce elegantly formatted output. I find it easiest to write a fully working example and then make little changes as needed so that knitr::render() can loop over the data sets.
