[R] vector of Vectors

[sclarke3 at illinois.edu]

I just learned that vectors can't contain vectors, which frankly simply confuses me (can you imagine arrays or lists in any other language not being able to contain arrays or lists?). At any rate, I need to create a data structure (size to be determined at runtime) which I will instantiate and then fill with vectors using a for loop. Clearly I'm new to the R game. Data Frame doesnt seem to be the right tool clearly.
