Read this book, "Multivariate Statistical Analysis: A Conceptual Introduction" by Sam Kash Kachigan. I think it's *great*, and perfect for someone without any statistical background.

Subject: [R] Using R for classifying new samples

I do not have any statistical background, So I shall apologise if I am asking trivial question or help.

I am trying to work with R.
The problem I have on hand is:
I have 2 sets of data(means & SD for each sample in the group of both sets). The sample size is massive(2000+ in each grp).
I have a new set of experimental data and I like to classify this to either of the grps based on statistical evidence.
I thought using Linear discriminant analysis of R(MASS package) I can solve this problem.
But unfortunately I am not quite sure its the right way and further with given my background I am not even sure how to prepare the data to test.

To explain my problem further, I have prepared a small set of data to be that it might be easy to suggest the right way to go ahead.The data is in the


What I would like to test is if the "query" belongs to grp 1 or 2(for all my samples,2000+)and if it can read out to me teh query belongs to grp_1 or grp_2. Is there some good examples that I can refer to which can teach me step wise right from preparing the data to testing???or would there be someone who can help me with this problem?????

Thanks a lot for your time...look forward to hear some help and suggestions
