This part can be simpler:
lapply(infert,table)
But extending it to the rest of the problem (i.e., 2-way tables) is
not trivial and can be confusing.

Hi:
Here's one way to do the pairwise tables. I'm restricting attention to
the variables with only a few levels, but the idea should be clear
enough.
# Put the variable names into a vector
vars - names(infert)[c(1, 3:6)]
# Use expand.grid() to generate all pairs of variables
