Using functions/loops for repetitive commands

Thanks David,

I did notice that and I got his code to work using wilcox.test for the
continuous variables.

The problem is that when I tried to alter the code to do chisq.test  
on my
categorical variables there is something wrong with the syntax and I  
don't
know what.

Right....
 > ?chisq.test
# No mention of a formula argument seen
 > ?chisq.test.formula
No documentation for 'chisq.test.formula' in specified packages and  
libraries:
you could try '??chisq.test.formula'

`chisq.test` doesn't have a formula method, so sending it a formula  
will fail.

Why aren't you sending it the arguments instead of turning them into  
strings?

Derek
