)Arguments
- x
a vector of values for which a frequency polygon is desired.
- plot
a logical indicating if a plot should be generated.
- ...
additional arguments passed on to
hist().- hist
a histogram object produced by
link{hist}().- freq
A logical indicating whether the vertical scale should be frequency (count).
- col
A color for the frequency polygon.
- lty
An integer indicating the line type.
- lwd
An integer indicating the line width.
- main
A title for the plot.
- sub
A sub-title for the plot.
- xlab
Label for the horizontal axis.
- ylab
Label for the vertical axis.
- xlim
A numeric vector of length 2.
- ylim
A numeric vector of length 2.
- axes
A logical indicating whether axes should be drawn.
- labels
A logical indicating whether labels should be printed or a character vector of labels to add.
- add
A logical indicating whether the plot should be added to the current plot
- ann
A logical indicating whether annotations (titles and axis titles) should be plotted.
Value
An object of class "freqpoly" (invisibly). Additionally, if plot is
TRUE, a plot is generated.
