It would be helpful to produce a script that reproduces the error on  
your system. And include details on the size of your data set and  
what you are doing with it. It is unclear what function is actually  
causing the error and such. Really, in order to do something about it  
you need to show how to actually obtain the error.

To my knowledge nothing _major_ has happened with the memory  
consumption, but of course R could use slightly more memory for  
specific purposes.

But chances are that this is not really memory related but more  
related to the functions your are using - perhaps a bug or perhaps a  
user error.
