I am using R. I have a column with 4 elements {car, bus, walk, train}. I would like to compare the car and bus with each other with the help of the 3 other columns. How can I do this?

For example, suppose that the other column is male/female, I would like to know how many are male or female for car and bus.

  • $\begingroup$ Do you want a table of counts for each pair of categories? Like table(d$vehicle, d$gender)? $\endgroup$
