Enter the command


and you will see:

  Matrix Multiplication
     Multiplies two matrices, if they are conformable.  If one argument
     is a vector, it will be promoted to either a row or column matrix
     to make the two arguments conformable.  If both are vectors it
     will return the inner product (as a matrix).
     x %*% y
