Thanks in Advance for ur help
You do not need to learn S. R is essentially a derivative work of S.
Some suggestions on getting started with R is to follow some online tutorials that uses sample code snippets.http://wiki.math.yorku.ca/index.php/R:_Getting_started
This will get you acquainted with the R format and programming domain. The idea is that you get familiar with the nuances of R.
Open up the console and follow along with some of those scripts. Once you get familiar with some of the basic usage and functions of R I suggest getting an R Reference Card. My favorite is Tom Short's Reference Card
Then I would suggest finding out specifics about R that you want to use it for. Use the handy R meta-search site Rseek to search for topics related to R.
Here you can find many statistical and optimization topics related to R. Look over the Task Views to see which packages in R that may be suited for your needs.
Lastly I recommend getting involved in the R online community. R-bloggers.com is an excellent site that aggregates a bunch of people that blog about R. It is a wealth of information about R topics and usage.
I agree with Larry, and he posted some things that were new to me.

When you have a question search the R help archive.
If you can't find the answer, try this: Write the question out, and create an example. In that process I usually find a better way to search for the answer, or find the answer. If you don't find an answer, then it's time to post the question to the group.
When you're frustrated by the R Gui in a few months, then explore the Eclipse plug in.
hi Mary, hope you are doing great.
my R is nt reading excel files, shows package does not exist, which is the package i need to use in order to read and edit data from excel files .
please guide on this
Jeromy Anglin's blog has a great compilation of R learning links. Some with videos.
thank you Larry,
i installed additional packages after downloading zip folders to my library.
to read excel file, i converted it to csv and then used usual read.csv() code.
dependencies=TRUEensures that any packages that
Rcmdrdepends on are also installed.
To use a package you have installed, either use the Packages-->Load package menu item or type
pkgname is the name of the package.
