sidebyside([termlaby:y,labels:c,rescale:tf,showconst:tf,boxcut:int]) |

sidebyside() produces a side-by-side plot of the effects and residuals of the current model; there must be an active model. A side-by-side plot plots the effects for each term against the term number, showing the relative sizes of the effects. When there are many effects or residuals, a boxplot is made instead of showing individual effects. There are no required arguments, but the following arguments alter the plot; in addition, any graphics arguments are passed through. Optional arguments are termlaby:real Specify y-value for term labels. This can be a single value or a vector of length equal to number of terms. labels:charvector Specify your own term labels. rescale:logic Should effects be divided by their standard errors. Default is F. This uses the standard errors as reported by secoefs() and may not be correct for all mixed models (secoefs() depends on terms labeled ERRORX). Residuals are divided by root MSE. showconst:logic Should the coefficient of the CONSTANT be shown? Default is F. boxcut:integer Cutoff for using a boxplot for a term instead of plotting individual effects. Default is 20. Example: Cmd> y <- vector(9,13,12,43,48,57,60,65,70,77,70,91,\ 15,13,20,66,58,73,75,78,90,97,108,99) Cmd> acid<-factor(rep(run(2),rep(12,2))) Cmd> style<-factor(rep(rep(run(4),rep(3,4)),2)) Cmd> anova("y=acid*style",silent:T) Cmd> sidebyside() #default plot Cmd> # specify term locations and labels Cmd> sidebyside(termlaby:vector(-50,-40,-30,-20),\ labels:vector("a","b","c","d"),boxcut:30) Cmd> # show the constant and rescale Cmd> sidebyside(dumb:T,showconst:T,rescale:T)
