To address issues #102 and #105, I changed the references to factor data types to character data types. In Episode 1 of this lesson, the instructions say to download the latest version of R, so I assume all students should be using R 4+ which changes the default option of
stringsAsFactors
toFALSE
.I also removed an
X
that appeared to be a typo, and switched a verb from singular to plural when it referred to data as plural.
