What exactly is an dgCMatrix-class. There are so many attributes.
...d it fit easily so I proceeded.
I find the TsparseMatrix indexing easier for my more naive notion of sparsity, although thinking about it now, I think I can see that the CsparseMatrix more closely resembles the "folded vector" design of dense R matrices. I will sometimes coerce CMatrix objeccts to TMatrix objects if I am working on the "inner" indices. I should probably stop doing that.
I sincerely hope my stumbling efforts have not caused any delays.

Thank you for your responses.
I guess I don't feel alone. I don't find the documentation go into any
detail.
I also find it surprising that,
> object.size(train$data)
1730904 bytes
> object.size(as.matrix(train$data))
6575016 bytes
the dgCMatrix actually takes less memory, though it *looks* like the
opposite.
Cheers!
