[R] R2.0.1 for Mac OS X 10.3 problem

2005-04-18 Thread Greg Arnold
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

This also is my experience (in Linux  MacOS X). The .RData need not be
corrupted, but you have corrupted your R installation by deleting or
corrupting some package using S4 methods (like failed upgrade of a S4
method package). When you start R so that it tries to restore those S4
objects in .RData, you get the error. Renaming or deleting .RData will
help, of course. Alternatively, in my case it helped to start R with
option --no-restore-data (in Mac when starting R from terminal -- where
you are all the time in Linux). Probably it would help to install again
the original S4 package. (In my case this happened when I tried Thomas
Yee's VGAM and then removed the package.)
