MARSS (version 3.4)

MARSSvectorizeparam: Vectorize or replace the par lists

Description

Converts MLEobj[["what"]] to a vector or assigns a vector to MLEobj[["what"]]. This is a utility function in the MARSS-package.

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.

Value

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

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$model$fixed). Appends matrix name to the row names in the par list.
