Phrasing suggestion for 01-starting-with-data.Rmd

[ereverman]

Hello,

I would suggest slightly rephrasing the explanation at line 358 of 01-starting-with-data.Rmd from "... when analyzing data we often want to look at partial statistics..." Reading on, it seems clear this means that the goal is to subset the data and calculate statistics for parts of the dataset, but this could be more obvious with something like "when analyzing data we often want to calculate statistics for specific subsets of the data frame..."

Also, there is a formatting issue in the .Rmd file that causes everything to be bold after combine on line 314. This doesn't seem to hinder the file when it is read into R on my computer, but I'm not sure if this is universally true.

Cheers,
Elizabeth
