Plot Methods for 'table' Objects

Description:

     This is a method of the generic 'plot' function for (contingency)
     'table' objects.  Whereas for two- and more dimensional tables, a
     'mosaicplot' is drawn, one-dimensional ones are plotted "bar
     like".

Usage:

     ## S3 method for class 'table':
     plot(x, type = "h", ylim = c(0, max(x)), lwd = 2,
           xlab = NULL, ylab = NULL, frame.plot = is.num, ...)

Arguments:

       x: a 'table' (like) object.

    type: plotting type.

    ylim: range of y-axis.

     lwd: line width for bars when 'type = "h"' is used in the 1D case.

xlab, ylab: x- and y-axis labels.

frame.plot: logical indicating if a frame ('box') should be drawn in
          the 1D case.  Defaults to true when 'x' has 'dimnames'
          coerceable to numbers.

     ...: further graphical arguments, see 'plot.default'.

Details:

     The current implementation (R 1.2) is somewhat experimental and
     will be improved and extended.

See Also:

     'plot.factor', the 'plot' method for factors.

Examples:

     ## 1-d tables
     (Poiss.tab <- table(N = rpois(200, lam= 5)))
     plot(Poiss.tab, main = "plot(table(rpois(200, lam=5)))")

     data(state)
     plot(table(state.division))

     ## 4-D :
     data(Titanic)
     plot(Titanic, main ="plot(Titanic, main= *)")
