R help - Nov 2003 - Questions in R

Hello,
I have 4 questions in R and I am looking for 4 answers!
the questions are the below:
1) is there a function in R for the Least Significant Difference method for
multiple comparisons?
2) Is there a function in R that gives me the studentized deleted residuals and
the leverage points?
3) is there a way that I could create a link in a program of mine, so as to
select an option when my program is running?
4) Whis function gives me the opprotunity to give data to my program while
it's running?That is, how can i give information, like cin in C++, to my
program will it is running in R.
 
Any answer would be useful.Thanks!

There is a multcomp package that implements many methods for multiple 
comparisons, but I'm not sure whether it does LSD.

rstudent() and hatvalues().

It's not altogether clear to me what you want to do, but see ?menu.

See ?readline.

I hope that this helps,
