[R] How to make an array of data.frames?

[Werner Wernersen]

Hi,

I am still struggling with the data structures in R. I
know how it works in C++ but how can I get such a
structure in R?

Here is what I want: 
x["a"]$dataframe1
x["a"]$dataframe2
x["a"]$dataframe3
x["b"]$dataframe1
x["b"]$dataframe2
x["b"]$dataframe3
x["c"]$dataframe1
x["c"]$dataframe2
x["c"]$dataframe3

And it would be nice if I could fill in "objects" a,
b, c one at a time successively.

What is the easiest way to get such a data structure?
It would be great if someone could give me some help
with this. 

Many thanks and kind regards,
  Werner
