Understanding Factors- Clarifiation

[hw85241]

This suggestion is for the Understanding Factors episode. For people who have a statistics background taking this lesson, they probably know that factors can be categorical or continuous. In R, though, factors are considered strictly categorical and what would be continuous is considered a variable. I think it would be good to point these facts out a little more specifically by adding a line in the introduction that says something like "R handles continuous data with variables instead of factors, but we will not be focusing on this in this episode." As someone with a descent statistics background, I was personally confused when I was first learning R because factors are only considered factors in the R context if they are categorical, even though continuous factors exist outside of R.

In a similar vein, could "binning" also be a handy way to turn ranges of continuous variables into factors? The cut function is very helpful here. See ?cut to learn more.

I am happy to provide an example if helpful.
