>>>So, if I run your codes that you sent yesterday, will I get the correct results for relative frequency etc.? It would be also great if you can sent me the output generated using your codes (on two groups as you showed yesterday).? It will help me in checking results much faster than running your code and see if that is the result (because I have to do some adjustment to your code for running in linux especially the ?dir()).?
