R help - Feb 2007 - Cross-tabulations next to each other

I have the following relatively simple problem. Say we have three  
factors, and we want to create a cross-tabulation against each of the  
other two:

x <- factor(rbinom(5, 1, 1/2))
y <- factor(rbinom(5, 1, 1/2))
z <- factor(rbinom(5, 1, 1/2))
table(x,y)
table(x,z)

This looks like:

    y
x   0 1
   0 2 0
   1 1 2

    z
x   0 1
   0 1 1
   1 2 1

I would like to get (surely this will look a mess in non-monospaced  
fonts):

    y    z
x   0 1  0 1
   0 2 0  1 1
   1 1 2  2 1

Or something along those lines. Then I would like to convert this to  
a LaTeX table, in the obvious sort of way.

I couldn't find an answer with a quick look through the  
documentation. Are these two things already done, before I try to  
roll my own?

maybe cbind() is close to what you're looking for, e.g.,

tb1 <- table(x, y)
tb2 <- table(x, z)

cbind(tb1, tb2)
