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

winjohn
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.

Re: 'last.warning' problem at startup; package Matrix (PR#8453)

Prof Brian Ripley
This *is* a bug in package Matrix and yes, bugs in packages can be bad
enough to stop a saved image (sic) being loaded.  You could have started R
--no-restore and load()ed it later.

Matrix has several uses of assignInNamespace in .onLoad and .onUnload, and
that is in package utils and so not necessarily loaded.  Try loading
Matrix with R_DEFAULT_PACKAGES=NULL to reproduce this.

R-bugs was not the appropriate place to report this, as the FAQ makes
quite clear.
