Predict from an lqs Fit
Predict from an resistant regression fitted by lqs.
## S3 method for class 'lqs' predict(object, newdata, na.action = na.pass, ...)
object |
object inheriting from class |
newdata |
matrix or data frame of cases to be predicted or, if |
na.action |
function determining what should be done with missing

arguments to be passed from or to other methods. |
This function is a method for the generic function
predict() for class lqs.
It can be invoked by calling predict(x) for an
object x of the appropriate class, or directly by
calling predict.lqs(x) regardless of the
class of the object.
Missing values in newdata are handled by returning NA if the
linear fit cannot be evaluated. If newdata is omitted and
the na.action of the fit omitted cases, these will be omitted on the
prediction.
A vector of predictions.
