I am trying to run a Principal Components analysis using a minimal spanning tree. What I begin with is a system of linear algebra and data which I am sure works, because I have used it before; but now I am trying to recreate an old project with the data and it is not working.
I get the following error after my second input, ''Inner::heads:Heads Transpose and TakeColumns at positions 3 and 2 are expected to be the same''.
The error has sense to it but I still do not completely understand what is my mistake.
Any help on this one?
''Inner::heads:Heads Transpose and TakeColumns at positions 3 and 2 are expected to be the same.''
