R help - Feb 2006 - Error in fun(...) : couldn't find function "assignInNamespace"

I started my laptop, opened a shell and get this error message:

Error in fun(...) : couldn't find function "assignInNamespace"
Error: .onLoad failed in 'loadNamespace' for 'Matrix'
Fatal error: unable to restore saved data in .RData

Here is some directory information:

-rw-rw-r--   1 chippy chippy 1222666 Feb  2 07:20 .RData
-rw-------   1 chippy chippy   21897 Feb  2 07:20 .Rhistory

Is .RData corrupted? I can run R in other directories.

No.  You've saved a reference to the Matrix namespace, and your Matrix has 
references to package utils in its startup without ensure utils is loaded.

The problem is in package Matrix: it has been reported before so 
hopefully will be fixed soon.

For now, load R --no-restore and start with load(".RData").
