Because rcpp packages wasnt mentioned there.

How to add merging two matrices by Row or Column
To arrange A and B as two rows of a matrix, use the semicolon. To concatenate two matrices, they must have compatible sizes. In other words, when you concatenate matrices horizontally, they must have the same number of rows. When you concatenate them vertically, they must have the same number of columns.
