Arguments
id |
the identifier list. This will become the dimnames of the final matrix, and must be a set of unique values. It's length determines the dimension of the final matrix |
blocksize |
the blocksize vector of the final matrix. If supplied, the sum of blocksizes must equal the dimension of the matrix. By default, the created matrix is as sparse as possible. |
