| \title{Extract Model Residuals} |
| \usage{ |
| residuals(object, \dots) |
| resid(object, \dots) |
| } |
| \arguments{ |
| \item{object}{an object for which the extraction of model residuals is |
| meaningful.} |
| \item{\dots}{other arguments.} |
| } |
| \value{ |
| Residuals extracted from the object \code{object}. |
| } |
| \description{ |
| \code{residuals} is a generic function which extracts model residuals |
| from objects returned by modeling functions. |
| |
| The abbreviated form \code{resid} is an alias for \code{residuals}. |
| It is intended to encourage users to access object components through |
| an accessor function rather than by directly referencing an object |
| slot. |
| |
| All object classes which are returned by model fitting functions |
| should provide a \code{residuals} method. (Note that the method is |
| for \samp{residuals} and not \samp{resid}.) |
| |
| Methods can make use of \code{\link{naresid}} methods to compensate |
| for the omission of missing values. The default, \code{\link{nls}} and |
| \code{\link{smooth.spline}} methods do. |
