[BioC] Questions about gene identifiers and probesets regulation

[Ana Conesa]

Dear List,

I am trying to find a function/way to get the coordinates of given
elements of an array. What I mean is the following:
- Let X be a 3D array
- I find the ordering of the elements in X by ord <- order(X) (this
is a vector)
- Now I want to get the x,y,z coordinates of each element of ord

Can anyone help me?

Thank you

Ana
