\title{Mosaic plot with information about missing/imputed values}
\usage{
mosaicMiss(
x,
delimiter = NULL,
highlight = NULL,
selection = c("any", "all"),
plotvars = NULL,
col = c("skyblue", "red", "orange"),
labels = NULL,
miss.labels = TRUE,
...
)
}
\arguments{
\item{x}{a matrix or \code{data.frame}.}
\item{delimiter}{a character-vector to distinguish between variables and
imputation-indices for imputed variables (therefore, \code{x} needs to have
\code{\link[=colnames]{colnames()}}). If given, it is used to determine the corresponding
imputation-index for any imputed variable (a logical-vector indicating which
values of the variable have been imputed). If such imputation-indices are
found, they are used for highlighting and the colors are adjusted according
to the given colors for imputed variables (see \code{col}).}
\item{highlight}{a vector giving the variables to be used for highlighting.
If \code{NULL} (the default), all variables are used for highlighting.}
\item{selection}{the selection method for highlighting missing/imputed
values in multiple highlight variables. Possible values are \code{"any"}
(highlighting of missing/imputed values in \emph{any} of the highlight
variables) and \code{"all"} (highlighting of missing/imputed values in
\emph{all} of the highlight variables).}
\item{plotvars}{a vector giving the categorical variables to be plotted. If
\code{NULL} (the default), all variables are plotted.}
\item{col}{a vector of length three giving the colors to be used for
observed, missing and imputed data. If only one color is supplied, the tiles
corresponding to observed data are transparent and the supplied color is
used for highlighting.}
\item{labels}{a list of arguments for the labeling function
\code{\link[vcd:labeling_border]{vcd::labeling_border()}}.}
\item{miss.labels}{either a logical indicating whether labels should be
plotted for observed and missing/imputed (highlighted) data, or a character
vector giving the labels.}
\item{\dots}{additional arguments to be passed to \code{\link[vcd:mosaic]{vcd::mosaic()}}.}
}
\value{
An object of class \code{"structable"} is returned invisibly.
}
\description{
Create a mosaic plot with information about missing/imputed values.
}
\details{
Mosaic plots are graphical representations of multi-way contingency tables.
The frequencies of the different cells are visualized by area-proportional
rectangles (tiles). Additional tiles are be used to display the frequencies
of missing/imputed values. Furthermore, missing/imputed values in a certain
variable or combination of variables can be highlighted in order to explore
their structure.
}
\note{
This function uses the highly flexible \code{strucplot} framework of
package \code{vcd}.
}
\examples{
data(sleep, package = "VIM")
## for missing values
mosaicMiss(sleep, highlight = 4,
plotvars = 8:10, miss.labels = FALSE)
## for imputed values
mosaicMiss(kNN(sleep), highlight = 4,
plotvars = 8:10, delimiter = "_imp", miss.labels = FALSE)
