Sitadri,
What operating system are you using? Have you loaded R onto you computer? If not I suggest you do so. You can than enter the command ?lm
which will give you information about lm command, the command used to perform linear regresssion. I would also suggest that you go to http://cran.r-project.org/doc/manuals/R-intro.html and do some reading of the introduction document. Once you have done this you should be able to get started using R and will be able to ask a question that we can more easily answer. John

 Folks, Two simple questions :

(1) I have a data set (call it data.xls) in a folder in my hard drive. How do I perform a simple regression between two variables from that data set?  After I click on 'R', what exactly do I type in?

(2) Where do I get to see the complete library of packages offered by R? In particular, I am interested in quantile regression and logistic regression.

Thanks.
