R help - Jun 2007 - Could not find lmer function in {Matrix} package

I am having trouble calling the lmer function in the {Matrix}  
package.  I first installed and loaded {Matrix} as follows:

 > install.packages("Matrix")
 > library(Matrix)

The package loaded successfully, however when I attempted to call  
lmer, I received the following message:

Error: could not find function "lmer"

I also tried:

< ?lmer

which produced no search results.

I have attempted these actions in both MacOSx R Versions 2.4.1 and  
2.5.0.  I have also tried this in Version 2.5.1. beta on a Windows  
machine.

Thanks in advance for any suggestions.

Steve

It's now in the lme4 package.

I don't think it's there.  I have had a look at the
ref doc and lmer does not show up.  

Have a look at
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/67904.html

It looks like it's in the lme4 package now.

And who told you  lmer() was in the Matrix package ?
It's in the lme4 package, and --- conceptually has always been there --
Only for some maintenance convenience (C code shared between
lme4 and Matrix) reasons, lmer() has actually been in the Matrix
package for some time in the past, 
however you were always supposed to say
    
    require(lme4)  or  library(lme4)

to get to lmer.
