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.
