MARSSvectorizeparam {MARSS} | R Documentation |
Vectorize or Replace the par List
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
.
Usage
MARSSvectorizeparam(MLEobj, parvec = NA, what = "par")
Arguments
MLEobj |
An object of class |
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.
