Hi dear all I'm doing some contingency tables and I'd like to know if it is posible to make only one table in R that shows me the responses of people who visit a place with some frecuency about one question with two posibilities (they are treated like two variables with options). I'm thinking of a table similar to the next below: Frecuencia (Frec) Alternative 1 Alternative 2 Good Bad Good Bad Todos los d??as Entre 4 y 5 veces por semana 2 veces por semana Entre 1 y 3 veces al mes Primera vez Sin respuesta Another thing I'd like to do is to make a contingency table that relates a categorical data with a numerical data. They are the frecuency of visit to a place with the ages of those people, but I need to summarize the age into intervals that outcomes from a Histogram. For instance, "hist" function with $breaks and $counts retunrs the intervals limits and frecuency of data into each interval. Frecuencia (Frec) Edad(Age) 15-20 20-25 25-30 30-35 Todos los d??as Entre 4 y 5 veces por semana 2 veces por semana Entre 1 y 3 veces al mes Primera vez Sin respuesta Thanks a lot for your help Adri??n C.
