LikertPercentCountColumns: Display likert plots with percents in the first column of...

In HH: Statistical Analysis and Data Display: Heiberger and Holland

Display likert plots with percents in the first column of panels and counts in the second column of panels.

Description

Display likert plots with percents in the first column of panels and counts in the second column of panels. Order the rows either in their original order or by the positive order of the percent display.

Usage

LikertPercentCountColumns(
           x, data,
           px=list( ## defaults designed for long QuestionName values
             LL=c(.00,  .50), ## and 7in x 7in window
             LP=c(.50,  .70),
             ML=c(.50,  .51),  ## arbitrary, visually center the labels and legend
             RP=c(.71,  .87),
             RL=c(.87, 1.00)),
           ...,
           QuestionName="Question",
           as.percent="Capture and then ignore this argument",
           positive.order=FALSE)

Arguments

x, data, positive.order	formula, data.frame, Logical. See likert.
...	other arguments that can be used for likert.
px	See as.TwoTrellisColumns5.
as.percent	Capture this argument and ignore it. The as.percent argument of likert will be TRUE in the left (Percent) column of the resulting "TwoTrellisColumns5" object and FALSE in the right (Count) column.
QuestionName	Character string containing the name of the column in data containing the values of the response variable.

Value

A "TwoTrellisColumns5" object, consisting of a list containing the constructed left, middle, and right trellis objects, and an attribute containing the px value. See as.TwoTrellisColumns5 for details.

Examples

## These are based on the Professional Challenges example in ?likert
data(ProfChal)

levels(ProfChal$Subtable)[6] <- "Prof Recog" ## reduce length of label

## See ?print.TwoTrellisColumns for this example using the original ordering

## Order both the plot of the count plot and the percent plot by the
## positive.order of the percent plot.
