[R] Latest revision of lme4 requires 'Matrix' >= 0.995.2 but that version is not available on CRAN

I see that Matrix, lme4 and SASmixed in zip format have been 'rolled back' to the previous versions - which I have now installed. Running 
Demand> fm1Demand <- lmer(log(d) ~ log(y) + log(rd) + log(rt) + 
    log(rs) + (1 | State) + (1 | Year), Demand)
Error: object "d" not found
Error in log(d) : unable to find the argument 'x' in selecting a method for function 'log'

- so it is not a complete 'roll back' - unless I've misunderstood something? Help will be appreciated...

Yes, but implementing this would require an even higher computational
effort to build and check Windows binary packages.

Since it looks like the Matrix problems are persisting, I will play back
the "old" versions of both packages to CRAN shortly.
