panel.dotplot.tb: Dotplot with evenly spaced tiebreakers.

Description

Dotplot with evenly spaced tiebreakers. Multiple hits on a specific x value are stacked.

Usage

panel.dotplot.tb(x, y, factor=.1,
                 jitter.data=TRUE, horizontal=TRUE,
                 max.freq=max(sapply(subsets, length)),
                 ...)

Warning

If the formula includes one or more conditioning factors, then the user is responsible for providing a value for max.freq. The default behavior is a different max.freq for each panel in a multi-panel display.

Details

Creates (possibly grouped) Dotplot of x against y. y is the `factor'.

Examples

x <- c(1,1,2,2,2,5,4,2,1,5)
y <- factor(letters[rep(1:2, 5)])

dotplot(x, panel=panel.dotplot.tb)
dotplot(x, panel=panel.dotplot.tb, factor=.2)
dotplot(y ~ x, panel=panel.dotplot.tb)
dotplot(y ~ x, panel=panel.dotplot.tb, cex=1.5, factor=.15)



quiz <- data.frame(scores=sample(10, 360, replace=TRUE),
                   date=rep(rep(c("0902", "0916", "0930"), c(40,40,40)), 3),
                   section=rep(
                     c("Stat1-3", "Stat1-5", "Stat1-8"),
                     c(120,120,120)))

dotplot(date ~ scores | section, data=quiz,
        panel=panel.dotplot.tb, factor=.5)

dotplot(date ~ scores | section, data=quiz,
        panel=panel.dotplot.tb, factor=.5,
        layout=c(1,3), between=list(y=1),
        main='Three quizzes for three sections of Stat 1')
