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").
