I have installed lme4 library, but when I try something with lmer()
function, I receive error message. On the other hand, I can use lme()
function from the same library. Are those two the very same function or
not? I am a bit confused.

I am using:
$platform: "i386-pc-linux-gnu"
$arch: "i386"
$os: "linux-gnu"
$system: "i386, linux-gnu"

$major: "2"
$minor: "0.1"
$year: "2004"
$month: "11"
$day: "15"

1. lme4 is a *package*, not a library
2. a function lme() is not part of recent versions of lme4. You told us 
you are using an ancient version of R, but nothing about the version of 
lme4 (which is porbably outdated as well, since new versions won't work 
on such an ancient version of R, I believe).
3. Why do you conceal the error message of lmer()?
Please read the posting guide and send information that is helpful for 
the helpers to help.

At least in recent versions of the lme4 package there's no `lme' function,
and in fact there's no fitting functions for (G)LMMs whatsoever. These
have been transfered to the Matrix package during the development process
-- the function you're looking for is called `lmer'.

            

      
      
      
    

        
2.2.0, so you must update (which is a good idea, anyway!).


HTH,
