MARSSvectorizeparam: Vectorize or Replace the par List

In gragusa/MARSS: Multivariate Autoregressive State-Space Modeling

Description

Converts MLEobj[["what"]] to a vector or assigns a vector to MLEobj[["what"]]. This is a utility function in the MARSS-package for marssMODEL objects of form="marss" and is not exported. Users achieve this functionality with coef.marssMLE.

Usage

MARSSvectorizeparam(MLEobj, parvec = NA, what="par")

Arguments

MLEobj	An object of class marssMLE.
parvec	NA or a vector. See Value.
what	What part of the MLEobj is being replaced or vectorized. Need to be a par list.

Details

Utility function to generate parameter vectors for optimization functions, and to set MLEobj[[what]] using a vector of values. The function bases the unlisting and naming order on names(MLEobj$marss$fixed). Appends matrix name to the row names in the par list.

Value

If parvec=NA, a vector of the elements of the what element. Otherwise, a marssMLE object with MLEobj[["what"]] set by parvec.
