Hi,

I have a problem accessing "lmer.R" from the Matrix package 0.995-10   
on a MacBook Pro after upgrading to 2.3.0.

 >  (fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
Error in do.call("lmerControl", control) :
	could not find function "lmerControl"

When I define the "lmerControl" function contained in "lmer.R"  
directly, the program stops at "subbars" which is the next function  
in "lmer.R".
So obviously, my new installation does not work properly.

 > (fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
Error in lmer(Reaction ~ Days + (Days | Subject), sleepstudy) :
	could not find function "subbars"

I use the following setup which I compiled with gcc4.0.3.
Version 2.3.0 Patched (2006-05-11 r38037)
i386-apple-darwin8.6.1

attached base packages:
[1] "methods"   "stats"     "graphics"  "grDevices" "utils"      
"datasets"  "base"

other attached packages:
       lme4    lattice     Matrix
"0.995-2"   "0.13-8" "0.995-10"

I have not run into any problems with other packages (e.g., installed  
automatically along with R, e.g., nlme, or by myself, e.g., HMisc).

I  had "lmer" working fine on this machine before I upgraded to  
2.3.0, but I get the same error when I go back to the 2..2.1  
(universal binary) now.

I also get the same error after installing "Matrix 0.995-8".

lmer works fine on another Macintosh G5 machine which I did not  
upgrade (R-version 2.2.1, powerpc-apple-darwin7.9.0, Matrix 0.995-4)

Thank you for your attention.

Best
Reinhold
