This combination was operating satisfactorily until I tried updating lme4 and Matrix. My attempts to do this ultimately broke R. The R console appears briefly, then collapses. I have tried downloading and reinstalling R without success. Typing 'R' into Terminal gives the error message bring up the usual introduction, then the error message: Error in methods:::mlistMetaName(mi, ns) : The methods object name for "coerce" must include the name of the package that contains the generic function, but there is no generic function of this name Fatal error: unable to restore saved data in .RData Can anyone help? Greg
It did not `break R': just rename your .RData which appears to have become corrupted. Please always start R with --vanilla before concluding it is broken.

I have the same problem, in Windows, and I think the .Rdata is not corrupted. Load R without loading the.Rdata file - move or rename it. Then library(lme4) and load the .Rdata - it should work. cheers, Horacio ---------- Horacio Montenegro PhD Student in Genetics and Molecular Biology Universidade Estadual de Campinas (Unicamp) phone: +55 19 3788 1151 --- Prof Brian Ripley <ripley at stats.ox.ac.uk> wrote:> It did not `break R': just rename your .RData which > appears to have become > corrupted. > > Please always start R with --vanilla before > concluding it is broken. > > On Mon, 18 Apr 2005, Greg Arnold wrote: > > > This combination was operating satisfactorily > until I tried updating lme4 and > > Matrix.
