Upgrading R Lessons to use R 4.0

Mon, 03 Aug 2020 00:00:00 +0000

Summary and timeline

In April 2020, R officially released version 4.0. One of the major changes was the removal of the default stringsAsFactors = TRUE when reading in data frames. This was tentatively announced in late July 2019 and officially announced in February 2020. While this change has been seen as a good thing by the majority of the R community as a step towards reducing common pitfalls, it produces an interesting pedagogical challenge for some of our lessons that use errors and warnings generated from this default behavior as mechanisms to introduce learners to the concept of factors.
