Extracting exemplars and prototypes Antti Arppe

Next, we transform using the multinomial2logical function the multinomial predictors into dummy predictor variables , which are simply true or false for each categorical value of the selected multinomial variables. The think data frame has three extralinguistic variables that we have decided to exclude from the following statistical modeling, namely Register, Section, and Author (which are columns 25, 26, and 27 in the original data frame). The results of this conversion are stored in the data frame think.logical.
