dotPlot creates a dot plot. For data in groups the dotPlot is displayed stacked in one or not-stacked in different plot regions.

1 2	dotPlot(x, group, xlim, ylim, col, xlab, ylab, pch, cex, breaks, stacked = TRUE, ...)

`x`	vector with numeric values which should be plotted.
`group`	(optional) vector for grouping the values (see examples).
`xlim`	vector giving the lower and upper limit of the x-axis.
`ylim`	vector giving the lower and upper limit of the y-axis.
`col`	vector containing numeric values or strings for different colors for the groups in the dot plot.
`xlab`	a title for the x axis: `title`.
`ylab`	a title for the y axis: `title`.
`pch`	a vector of integers specifying symbols or a single character to be used for plotting points for the different groups in the dot plot.
`cex`	the amount by which points and symbols should be magnified relative to the default.
`breaks`	a vector giving the breakpoints for the binning of the values in x.
`stacked`	a logical vector specifying whether the single groups should be plotted in a stacked dot plot or in a single one. By default `stacked` is set to ‘TRUE’.
`...`	further graphical parameters (see `par`)

values in x are assigned to the bins defined by breaks. The actual binning is done using hist.

dotPlot a invisible matrix containing NA's and numeric values representing values in a bin. The number of bins is given by the number of columns of the matrix.

#dot plot with groups and no stacking
