[Rd] 'last.warning' problem at startup; package Matrix (PR#8453)

[winjohn@webone.com.au]

On starting an R session, I get the messages:

  Fatal errir: unable to restore save data in .RData

  Error in fun(...): couldn't find function "assignInNamespace"

  Error: .onLoad failed in 'loadNamespace' for 'Matrix'

The only object in my .RData is last.warning, thus:

  > last.warning
  $"optim or nlminb returned message false convergence (8)"
  "LMEoptimize<-"(`*tmp*`, value = list(maxIter = 200, tolerance = 
1.49011611938477e-08,
      msMaxIter = 200, msVerbose = 0, niterEM = 15, EMverbose = FALSE,
      PQLmaxIt = 30, analyticGradient = TRUE, analyticHessian = FALSE))

This was generated by a call, in a previous session,to lmer()
There may be a problem with the package Matrix, but it seems a bit
extreme that this prevents restoration of the session.
