plot.fraction function

Plots a fraction of the data as a cluster

Plots a convex hull or a star containing a specified percentage of the data. Used to plot clusters.

## S3 method for class 'fraction'
plot(x, add = TRUE, center = FALSE, 
centerlabel = "Center", initial = FALSE, type = "ch", ...)

Arguments

• x: An object with class fraction obtained from Fraction.
• add: Should the fraction be added to the current plot?
• center: Should the center be plotted?
• centerlabel: Label for the center.
• initial: Should the initial data be plotted?
• type: Type of plot. Can be: "ch"- Convex Hull or "st" - Star (Joining each point with the center)
• ...: Any other graphical parameter that can affects the plot (as color, etc ...)
