Since R v4.0.0, strings are no longer automatically converted to factors. As a consequence when importing data with functions such as read.csv(), e.g.
bird <- read.csv("data/birdsdiet.csv")
2 different behaviors for R 3.6. and R 4.0. are expected (which is the reason why Travis is currently failing). To avoid this, stringsAsFactors should be specified, e.g.
