This function combines customized layers into a DGP or linked (D)GP structure.
Usage
combine(...)
Value
A list defining a DGP structure (for struc of dgp()) or a linked (D)GP structure
(for struc for lgp()).
Arguments
...
a sequence of lists:
For DGP emulations, each list represents a DGP layer and contains GP nodes (produced by kernel()), or
likelihood nodes (produced by Poisson(), Hetero(), or NegBin()).
For linked (D)GP emulations, each list represents a system layer and contains emulators (produced by gp() or
dgp()) in that layer.
