Reflection Questions:

How was the install process? Anything I should know for future students? The install process was slightly confusing, especially as a mac student. The multiple downloads and installations were definitiely a learning curve, but eventually things started to seem a little easier. For future students, I would provide multiple videos and step-by-steps to break things down even more. Additionally, I think the install process would be easier if the professor’s screen mirrored students’ screens as if everyone was installing for the first time. This would make the walk through and directions simpler to follow.

Have you used any statistical software before? I have never used statistical software before and have no experience with statistical softwares.

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
