The predictions for the nonlinear model represented by
object are
obtained at the covariate values defined in
newdata.
USAGE:
predict(object, newdata, na.action, naPattern)
REQUIRED ARGUMENTS:
object
an object inheriting from class
gnls, representing
a generalized nonlinear least squares fitted model.
OPTIONAL ARGUMENTS:
newdata
an optional data frame to be used for obtaining the
predictions. All variables used in the nonlinear model must be present
in the data frame. If missing, the fitted values are returned.
na.action
a function that indicates what should happen when
newdata contains
NAs. The default action
(
na.fail) causes the function to print an error message and
terminate if there are any incomplete observations.
naPattern
an expression or formula object, specifying which returned
values are to be regarded as missing.
