Crosstab with multiple items

Question

In SPSS, it is (relatively) easy to create a cross tab with multiple variables using the factors (or values) as the table heading. So, something like the following (made up dat

Answer 1

The Hmisc package has the summary.formula function that can do something along the lines you want. It is very flexible, so look at the help page for examples, but here is an application to your problem:

library(Hmisc)
dd <- data.frame(Q1=sample(1:3, 20, replace=T), Q2=sample(1:3, 20, replace=T), 
                 Q3=sample(1:3, 20, replace=T))  #fake data
summary(~Q1+Q2+Q3, data=dd, fun=table)

This gives the following result:

 Descriptive Statistics  (N=20)

 +------+-------+
 |      |       |
 +------+-------+
 |Q1 : 1|25% (5)|
 +------+-------+
 |    2 |45% (9)|
 +------+-------+
 |    3 |30% (6)|
 +------+-------+
 |Q2 : 1|30% (6)|
 +------+-------+
 |    2 |35% (7)|
 +------+-------+
 |    3 |35% (7)|
 +------+-------+
 |Q3 : 1|35% (7)|
 +------+-------+
 |    2 |30% (6)|
 +------+-------+
 |    3 |35% (7)|
 +------+-------+

The possible values are given in rows, because it has the flexibility of different sets of values for different variables. You might be able to play with the function parameters (like method and fun) to get the other direction.
