predict.grplasso {grplasso} | R Documentation |
Obtains predictions from a grplasso
object.
## S3 method for class 'grplasso'
predict(object, newdata, type = c("link", "response"),
na.action = na.pass, ...)

A matrix whose columns correspond to the different values of
the penalty parameter lambda
of the grplasso
object.
If newdata
is given, offsets specified by offset
in the
fit by grplasso.default
will not be included in predictions,
whereas those specified by an offset term in the formula will be considered.
