Re: [R] create one bigger matrix with one smaller matrix

2015-12-31 Thread Bert Gunter
Well, all of the solutions proposed are a bit tricky in that the matrix must be "constructed" by hand. They are also reinventing wheels. What I think you really want is the kronecker product, which is the matrix operation that does exactly what you want. e.g. A <- matrix(1:4, nr=2) to create a ne
