getpar {mrds} | R Documentation |
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 |
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.
