getpar: Extraction and assignment of parameters to vector

In DistanceDevelopment/mrds: Mark-Recapture Distance Sampling

Extraction and assignment of parameters to vector

Description

Extracts parameters of a particular type (scale, shape, adjustments or g0 (p(0))) from the vector of parameters in ddfobj. All of the parameters are kept in a single vector for optimization even though they have very different uses. assign.par parses them from the vector based on a known structure and assigns them into ddfobj. getpar extracts the requested types to be extracted from ddfobj.

Usage

getpar(ddfobj, fitting = "all", index = FALSE)

Arguments

ddfobj	distance sampling object (see create.ddfobj)
fitting	character string which is either "all","key","adjust" which determines which parameters are retrieved
index	logical that determines whether parameters are returned (FALSE) or starting indices in parameter vector for scale, shape, adjustment parameters

Value

index==FALSE, vector of parameters that were requested or index==TRUE, vector of 3 indices for shape, scale, adjustment

Note

Internal functions not intended to be called by user.
