This function takes the model specification arguments to the crwMLE
function and displays a table
with the parameter names in the order that crwMLE
will use during model fitting. This is useful for specifying
values for the fixPar
or theta
(starting values for free parameters) arguments.
displayPar(
mov.model = ~1,
err.model = NULL,
activity = NULL,
drift = FALSE,
data,
Time.name,
theta,
fixPar,
...
)
A data frame with the following columns
The names of the parameters specified by the arguments.
The values specified by the fixPar
argument for fixed values of the parameters. In model fitting,
these values will remain fixed and will not be estimated.
This column provides the index of each element of the theta argument and to which parameter it corresponds.
If a value is given for the theta
argument it will be placed in this column and its elements will
correspond to the thetaIdx
column.
formula object specifying the time indexed covariates for movement parameters.
A 2-element list of formula objects specifying the time indexed covariates for location error parameters.
formula object giving the covariate for the stopping portion of the model.
logical indicating whether or not to include a random drift component.
data.frame object containing telemetry and covariate data. A
SpatialPointsDataFrame
object from the package 'sp' will also be accepted.
character indicating name of the location time column
starting values for parameter optimization.
Values of parameters which are held fixed to the given value.
Additional arguments (probably for testing new features.)
