Creating the mean using algebra matrix
Dear all,
I wanted to create the mean using a algebra matrix.
so I tried this one:
> meanAnimals <- new3%*%factorial
(Calculates the matrix multiplication of the new3 * factorial).
But I get the following error message:
Error in new3 %*% factorial : non-conformable arguments
These are my matrices:
> new3
[,1] [,2]
[1,] 1.350 8.1
[2,] 465.000 423.0
