barchart.table {lattice}  R Documentation 
Contingency tables are often displayed using barcharts and dotplots. These methods are provided for convenience and operate directly on tables. Arrays and matrices are simply coerced to be a table.
## S3 method for class 'table': barchart(x, data, groups = TRUE, origin = 0, stack = TRUE, ...) ## S3 method for class 'array': barchart(x, data, ...) ## S3 method for class 'matrix': barchart(x, data, ...) ## S3 method for class 'table': dotplot(x, data, groups = TRUE, ...) ## S3 method for class 'array': dotplot(x, data, ...) ## S3 method for class 'matrix': dotplot(x, data, ...)
x 
a table , array or matrix object.

data 
should not be specified. If specified, will be ignored with a warning. 
groups 
logical, whether to use the last dimension as the grouping variable in the display. 
origin, stack 
arguments to panel.barchart controlling the display. The
defaults for the table method are diffrent.

... 
other arguments, passed to the underlying formula
method.

The first dimension is used as the variable on the vertical axis. The
last dimension is optionally used as a grouping variable (to produce
stacked barcharts by default). All other dimensions are used as
conditioning variables. The order of these variables cannot be
altered (except by permuting the original argument using
t
or aperm
). For more flexibility, use
the formula method after converting the table to a data frame using
the relevant as.data.frame
method.

update
method can be used to
update components of the object and the
print
method (usually called by
default) will plot it on an appropriate plotting device.
