Dear R Helpers, First, I apologize for asking for help on the first of my topics. I have been looking at the posts and pages for apply, tapply etc, and I know that the solution to this must be ridiculously easy, but I just can't seem to get my brain around it. If I want to produce a set of tables for all the variables in my data, how can I do that without having to type them into the table command one by one. So, I would like to use (t? s? r?)apply to use one command instead of the following set of table commands:
data(infert, package = "datasets") attach(infert) table.education<-table(education) table.age<-table(age) table.parity<-table(parity) etc. To make matters worse, what I subsequently need is the chi-square for each and all of the pairs of variables. Such as: chi.education.age<-chisq.test(table(education,age)) chi.education.parity<-chisq.test(table(education,parity)) chi.age.parity<-chisq.test(table(age,parity)) etc. Your guidance would be much appreciated. --John J.
