I'm not sure what you are trying to do: modulo arithmetic isn't exactly splitting a matrix into 2. Or even remotely.
Regardless of the goal, when numbers are shown in quotes, it's a sure sign that R thinks they are strings, and thus non-number, just as the error message (not a warning) states. To help further, we'd need a clear statement of your goals and a reproducible example, as in the posting guide.
