I'm trying to convert a column of strings (nominal types) to a set of
boolean / binary / logical values. For example, in the column there is red,
blue, green and yellow. There are 100 rows and each has a colour. I want to
convert the column to 4 columns: red, blue, green,yellow and then either 1
or 0 put in the relevant row.
