Re: [R] Eigenvectors and values in R and SAS

Here is an example that may be helpful. A <- matrix(c(-3,5,4,-2),nrow=2,byrow=TRUE) eigs <- eigen(A) eigs $values [1] -7 2 $vectors [,1] [,2] [1,] -0.7808688 -0.7071068 [2,] 0.6246950 -0.7071068 The eigenvectors may be scaled differently because they are not unique (or have

[R] Eigenvectors and values in R and SAS

Hi, I was wondering if function eigen() does something different from the function call eigen() in SAS. I'm in the process of translating a SAS code into a R code and the values of the eigenvectors and eigenvalues of a square matrix came out to be different from the values in SAS. I would also
