Arguments

x
For the formula method, a model formula. All terms in the formula must be the names of columns in the data.frame argument data or the special abbreviation . only on the right-hand-side. Functions of the names wil
data
For the formula method, a data.frame. Do not use variable names ".value" or ".variable".
ReferenceZero
Numeric scalar or NULL. The position in the range seq(0, attr(x, "nlevels")+.5, .5) where the reference line at 0 will be placed. attr(x, "nlevels") is the number of columns of the original argument
value
Name of the numeric variable containing the data when the formula method is used with the long data form. The predictor in the formula will be a factor name. The name of the predictor will be used as the title in the key.
levelsName
(optional) Name of the implied factor distinguishing the columns of the response variables when the formula method is used with the wide data form. This name will be used as the title in the key.
positive.order
If FALSE, the default value, the original order of the rows is retained. This is necessary for arrays, because each panel has the same rownames. If TRUE, rows are ordered within each panel with the row whose bar
data.order
formula method only. If positive.order is TRUE, this data.order variable is ignored. If FALSE, the default value, and the rows are specified by a factor, then they are o
as.percent
When as.percent==TRUE or as.percent=="noRightAxis", then the values in each row are rescaled to row percents. When as.percent==TRUE the original row totals are used as rightAxisLabels
as.table
Standard lattice argument. See barchart.
par.settings.in, scales.in, auto.key.in, panel.in
These are placeholders for lattice arguments that lets the user specify some lattice par.settings and still retain the ones that are prespecified in the plot.likert.default.
ylab, xlab, ylab.right, xlab.top, main
Standard lattice graph labels in barchart.
right.text.cex
The right axis, as used here for the "Row Count Totals", has non-standard controls. It's cex follows the cex of the left axis, unless this argument is used to override that value. When code{horizontal=FALSE}, the
between
Standard lattice argument.
col
Vector of color names for the levels of the agreement factor. Although the colors can be specified as an arbitrary vector of color names, for example, col=c('red','blue','#4AB3F2'), usually specifying one of the diverging palet
colorFunction, colorFunctionOption
reference.line.col
Color for reference line at zero.
col.strip.background
Background color for the strip labels.
key.border.white
Logical. If TRUE, then place a white border around the rect in the key, else use the col of the rect itself.
horizontal
Logical, with default TRUE indicating horizontal bars, will be passed to the barchart function by the plot.likert method. In addition, it interchanges the meaning of resize.height and
...
other arguments. These will be passed to the barchart function by the plot.likert method. Arguments to the lattice auto.key=list() argument (described in
strip.left, strip
Logical. The default strip.left=TRUE places the strip labels on the left of each panel as in the first professional challenges example. The alternative strip.left=FALSE puts the strip labels on the top of
condlevelsName, strip.left.values, strip.values, strip.par, strip.left.par, layout
Arguments which will be passed to ResizeEtc.
xName
Name of the argument in its original environment.
rightAxis
logical. Should right axis values be displayed? Defaults to FALSE unless rightAxisLabels are specified.
rightAxisLabels
Values to be displayed on the right axis. The default values are the row totals. These are sensible for tables of counts. When the data is rescaled to percents by the as.percent=TRUE argument, then the rightAxisLabels<
resize.height.tuning
Tuning parameter used to adjust the space between bars as specified by the resize.height argument to the ResizeEtc function.
h.resizePanels, resize.height
Either character scalar or numeric vector. If "nrow", then the panels heights are proportional to the number of bars in each panel. If "rowSums" and there is exactly one bar per panel, then the panels heights
w.resizePanels, resize.width
Numeric vector. The panel widths are proportional to the numbers in the argument.
box.ratio
If there are more than one bar in any panel, then this defaults to the trellis standard value of 2. If there is exactly one bar in a panel, then the value is 1000, with the intent to minimize the white space in the panel. In t
panel
panel function eventually to be used by barchart.
xscale.components, yscale.components
See yscale.components.default. xscale.components.top.HH constructs the top x-axis labels, when needed, as the names of the bottom x-axis labels.
xlimEqualLeftRight
Logical. The default is FALSE. If TRUE and at and labels are not explicitly specified, then the left and right x limits are set to negative and positive of the larger of the absolute valu
xTickLabelsPositive
Logical. The default is TRUE. If TRUE and at and labels are not explicitly specified, then the tick labels on the negative side are displayed as positive values. When !horizontal
reverse
Logical. The default is FALSE. If TRUE, the rows of the input matrix are reversed. The default is to plot the rows from top-to-bottom for horizontal bars and from left-to-write for vertical bars. re

Value

  • A "trellis" object containing the plot. The plot will be automatically displayed unless the result is assigned to an object.

Details

The counts (or percentages) of respondents on each row who agree with the statement are shown to the right of the zero line; the counts (or percentages) who disagree are shown to the left. The counts (or percentages) for respondents who neither agree nor disagree are split down the middle and are shown in a neutral color. The neutral category is omitted when the scale has an even number of choices. It is difficult to compare lengths without a common baseline. In this situation, we are primarily interested in the total count (or percent) to the right or left of the zero line; the breakdown into strongly or not is of lesser interest so that the primary comparisons do have a common baseline of zero. The rows within each panel are displayed in their original order by default. If the argument positive.order=TRUE is specified, the rows are ordered by the counts (or percentages) who agree. Diverging stacked barcharts are also called "two-directional stacked barcharts". Some authors use the term "floating barcharts" for vertical diverging stacked barcharts and the term "sliding barcharts" for horizontal diverging stacked barcharts. All items in a list of named two-dimensional objects must have the same number of columns. If the items have different column names, the column names of the last item in the list will be used in the key. If the dimnames of the matrices are named, the names will be used in the plot. It is possible to produce a likert plot with a list of objects with different numbers of columns, but not with the plot.likert.list method. These must be done manually by using the ResizeEtc function on each of the individual likert plots. The difficulty is that the legend is based on the last item in the list and will have the wrong number of values for some of the panels. A single data.frame x will be plotted as data.matrix(x[sapply(x, is.numeric)]). The subscripting on the class of the columns is there to remove columns of characters (which would otherwise be coerced to NA) and factor columns (which would otherwise be coerced to integers). A data.frame with only numeric columns will work in a named list. A list of data.frame with factors or characters will be plotted by automatically removing columns that are not numeric. ftable and structable arguments x will be plotted as as.table(x). This changes the display sequence. Therefore the user will probably want to use aperm on the ftable or structable before using plot.likert. The likert method is designed for use with "likert" objects created with the independent likert package. It is not recommended that the HH package and the likert package both be loaded at the same time, as they have incompatible usage of the exported function names likert and plot.likert. If the likert package is installed, it can be run without loading by using the function calls likert::likert() and likert:::plot.likert().

## Professional Challenges example.
##
## The data for this example is a list of related likert scales, with
## each item in the list consisting of differently named rows.  The data
## is from a questionnaire analyzed in a recent Amstat News article.
## The study population was partitioned in several ways.  Data from one
## of the partitions (Employment sector) was used in the first example
## in this help file.  The examples here show various options for
## displaying all partitions on the same plot.

## 5. putting the x-axis tick labels on top for horizontal plots
##    putting the y-axis tick lables on right for vertical plots
##
## This non-standard specification is a consequence of using the right
## axis labels for different values than appear on the left axis labels
## with horizontal plots, and using the top axis labels for different
## values than appear on the bottom axis labels with vertical plots.
