Referencing Styles : APA knitR 2 Interpretive Research Qualitative Analysis Statistics in R First, go back and fix up your initial knitR assignment. Your document should not have any of the default knitR text that is automatically loaded. Every section that has R code in it should have a paragraph describing what you're doing and why. You can remove some of the functions that don't make any sense if you'd like. Try and make it look like a research paper! Start with the slides from Session 8. If you haven't already done so, choose the mpg, cyl. am, and gear variables and do the transformations necessary, only do them all correctly as described later in the slide deck. From no on, use na.rm to remove NA values. Demonstrate how many cars have automatic and manual transmissions, and demonstrate the proportions of each. Create a histogram of cars $mpg with text describing what it is that I'm looking at. Then create a histogram of cars $mpg with a density plot overlaid on it. Build a boxplot of the data that shows mpg for the groups defined by cyl, and be sure to write a nice description of what it is we looking at. Finally, go back to the original data. I want you to perform correlations between mpg and wt, mpg and disp, and mpg and hp. Show the code and results. Then write a couple paragraphs talking about the meaning of these three correlations.
