That _is_ a problem. It _should_ be an integer atomic vector, although  
it appears to be the correct length (at least is the same as  
my .Random.seed which has the same leading entry, 403, as yours)  and  
it appears to be all integers. Something you have done or some program  
has done has altered the default value. It is possible that this  
problem assignment has been saved in your (invisible) .Rdata file.

It is generally a bad idea to do anything to .Random.seed, but I don't  
see any harm at this point in trying this:

.Random.seed <- unlist(.Random.seed)

(... and then trying to install ggplot2)


That should get rid of the 'data.frame' attribute. I would also track  
down your .Rdata file and maybe also your .Rhistory file and delete  
them. You will need to learn how to do this in a Terminal session or  
you will need to learn how to display invisible files in Finder.app.  
The archives of the SIG-Mac list will have instructions.
