int.plot.default {pda} | R Documentation |
An interaction plot shows the mean responses for each
level of the object
at each level of the group
.
## Default S3 method: ci.plot(object, response, group, xlab, ylab, bar.plot="ci", ...) ## Default S3 method: int.plot(object, response, group, xlab, ylab, ...)
object |
factor to be plotted on the horizontal axis. |
response |
numeric vector. |
group |
factor whose levels will be separate traces. |
... |
optional specification of other parameters to be passed
to plotting routines and/or to the bar-drawing routines
lsd.bar and se.bar . There are some parameters, such
as width and edge which can change to plotting
area. |
bar.plot |
"lsd" (default for int.plot ), "ci" (default for
ci.plot ), "test", "ellipse" or "none". The "test" is a
sqrt(2) contraction of confidence interval for approximate graphical
comparisons of means.
|
xlab,ylab |
x and y axis labels |
list containing sd, rdf, level and sample size, and either lsd (lsd.plot) or width (ci.plot).
