1. Create a `big.matrix` object with the appropriate dimensions using `init = NULL`. 2. For each of the arguments to `cbind` (or `rbind`), copy the values into the appropriate locations.
Thanks @adamryczkowski. I've merged the pull request.
I'm happy to take a pull request for this one. Otherwise, I think I can get to it in the next few weeks.
On Linux and Windows you can create big matrices backed by sparse files by leaving the `init` argument as `NULL`. The size of the backing file will depend on the...
Thanks for the note. I've trying to get it on CRAN for the last few weeks. There is significant friction in this process because of reverse dependencies as well as...
Hi @rdrr1990. I vaguely remember a problem with the clang sanitizer options not allowing inheritance options, which are relevant when a `SharedBigMatrix` type needs methods from the `BigMatrix` type. I'm...
I'm not sure. As mentioned before I've only seen this when the clang sanitizer was set to not allow inheritance. Note that a `FileBackedBigMatrix` inherits from a `SharedBigMatrix`, which inherits...
This might indicate a memory mapping issue. Can you try creating a much smaller `big.matrix` object, like 10x10, and see if you get the same error?
Does it really crash the operating system or does it crash R? If the latter, is there an error message?
@cdeterman I think that's correct. At one point we linked bigmemory to the 64-bit api for the MKL in `bigalgebra` but since each of the BLAS set ups were slightly...
