One of the pre-loaded datasets in R looks at the vitamin C content in cabbages as a function of Cabbage size, Date, and Cultivar. Cabbage size is numerical, Date is categorical with 3 levels, and Cultivar is categorical with 2 levels. There are 60 observations in the dataset. Your model looks like this: VitC ~ Date * HeadWt + Cult, data = cabbages It has an R-squared value of 0.687. For the above model, calculate the omnibus F statistic for the full model
