There isn't a simple answer to this question.  Vectors have a maximum 
length of about 2 billion entries, and matrices are stored as vectors.  
Most often you will run out of memory before you hit that limit, because 
most functions in R work on data that's held in memory.  However, on a 
64 bit system you could have a lot of memory, and then it would be 
important.

Dataframes are lists of vectors, so they can be *much* larger than matrices.
