non numeric argument to binary operator

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.

hi i have a huge matrix and want to split it into 2. with the command %%2.
but i get this warning message: *"Error in mmat%%2 : non-numeric argument to
binary operator*"

here's the bit from my matrix:
 V1                                                   V2
[1,] "Affymetrix:CompositeSequence:ATH1-121501:244901_at" "2.653"
[2,] "Affymetrix:CompositeSequence:ATH1-121501:244902_at" "1.753"
