| \title{Extract Model Weights} |
| \usage{ |
| weights(object, \dots) |
| } |
| \arguments{ |
| \item{object}{an object for which the extraction of model weights is |
| meaningful.} |
| \item{\dots}{other arguments passed to methods.} |
| } |
| \description{ |
| \code{weights} is a generic function which extracts fitting weights from |
| objects returned by modeling functions. |
| |
| Methods can make use of \code{\link{napredict}} methods to compensate |
| for the omission of missing values. The default methods does so. |
| } |
| \value{ |
| Weights extracted from the object \code{object}: the default method |
| looks for component \code{"weights"} and if not \code{NULL} calls |
| \code{\link{napredict}} on it. |
