50 We use as an example a simple R datasert
, chickwts
, which has one
51 nominal categorical variable and one continuous categorical
52 variable. This dataset can be accessed in R as follows

60 1st Qu.:204.5 horsebean:10
61 Median :258.0 linseed :12
62 Mean :261.3 meatmeal :11
63 3rd Qu.:323.5 soybean :14
64 Max. :423.0 sunflower:12
