For a given detection function, it computes the initial values for the parameters including scale and shape parameters and adjustment function parameters if any. If there are user-defined initial values only the parameters not specified by the user are computed.
setinitial.ds(ddfobj, width, initial, point, left)
sethazard(ddfobj, dmat, width, left, point)
distance detection function object
half-width of transect or radius of point count
list of user-defined initial values with possible elements:
scale
, shape
, adjustment
if TRUE
, point count data; otherwise, line transect data
left truncation
xmat
from ddfobj
vector of initial scale parameter values
