Effect Displays (effects)
is an R
graphical or tabular display of terms in several kinds of statistical models.
There is an article
in the Journal of Statistical Software
that describes an earlier version the package, which handled linear
and generalized linear models; the current version handles multinomial
and proportional-odds logit models as well, as described in another article in the JSS
. Some additional models currently handled by the package -- mixed-effects models fit by lmer
in the lme4
package or lme
in the nlme
package, and models fit by generalized least squares using gls
in the nlme
package -- are described in the effects
The effects package may be downloaded from CRAN
(the Comprehensive R Archive Network), either in
source form, or as compiled binaries for various Windows systems, Macintoshes,
and Linux/Unix systems. A portable-document-format
(pdf) file with the help pages is also available there.
The current version of the effects package was written by John Fox, Sanford Weisberg, and Jangman Hong.
