Assigns 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.
assign.par(ddfobj, fpar)distance sampling object (see create.ddfobj)
parameter vector
if index==FALSE, vector of parameters that were requested or index==TRUE, vector of 3 indices for scale, shape, adjustment
getpar extracts the requested types to be extracted from ddfobj.
