[R] matrix of bins with different length

please help to define the following data structure:
I would like to have a matrix, where every element is a container of
different size , containing real numbers. The containers (bins) are
addressed by an index pair [i,j] (i is number of corresponding row of
the matrix, j is the coloumn of the matrix). The containers are
initially empty, I would like to fill them dynamically (put certain
numbers into different bins in each iteration).
I can not define a 3 dimensional array, because I don't know the
length of the third dimension in advance, and because the vectors
(containers) in the matrix are usually of different length.
Any help greatly appreciated,
