Dear all r-users,
I am getting a big problem with matrix multiplication
suppose I have,
> weight

But when I want to get [transpose(weight)][s][weight] using following
syntax,
t(weight)%*%s%*%weight
I got error:
Error in t(weight) %*% s %*% weight : requires numeric matrix/vector
arguments
Can anyone please tell me that where my error is?
Thanks and regards,
