| \title{Compute Tables of Results from an Aov Model Fit} |
| \description{ |
| Computes summary tables for model fits, especially complex \code{aov} |
| fits. |
| } |
| \usage{ |
| model.tables(x, \dots) |
| |
| \method{model.tables}{aov}(x, type = "effects", se = FALSE, cterms, \dots) |
| |
| \method{model.tables}{aovlist}(x, type = "effects", se = FALSE, \dots) |
| } |
| \arguments{ |
| \item{x}{a model object, usually produced by \code{aov}} |
| \item{type}{type of table: currently only \code{"effects"} and |
| \code{"means"} are implemented. Can be abbreviated.} |
| \item{se}{should standard errors be computed?} |
| \item{cterms}{A character vector giving the names of the terms for |
| which tables should be computed. The default is all tables.} |
| \item{\dots}{further arguments passed to or from other methods.} |
| } |
| \details{ |
| For \code{type = "effects"} give tables of the coefficients for each |
| term, optionally with standard errors. |
| |
| For \code{type = "means"} give tables of the mean response for each |
| combinations of levels of the factors in a term. |
| |
| The \code{"aov"} method cannot be applied to components of a |
| \code{"aovlist"} fit. |
| } |
| \value{ |
| An object of class \code{"tables.aov"}, as list which may contain components |
| \item{tables}{A list of tables for each requested term.} |
| \item{n}{The replication information for each term.} |
| \item{se}{Standard error information.} |
| } |
| \section{Warning}{ |
| The implementation is incomplete, and only the simpler cases have been |
| tested thoroughly. |
| |
| Weighted \code{aov} fits are not supported. |
