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

Can anyone help me out of this?
