the pie chart represents amount of values given in data.
Piechart(Datavector,Names,Labels,MaxNumberOfSlices,
main='',col,Rline=1,...)silent output by calling invisible of a list with
[1:k] percent values visualized in fanplot
[1:k] see input Labels, only relevant ones
[1:n] a vector of n non unique values
Optional,
[1:k] names to search for in Datavector, if not set unique of Datavector is calculated.
Optional, [1:k] Labels if they are specially named, if not Names are used.
Default is k, integer value defining how many labels will be shown. Everything else will be summed up to Other.
Optional, title below the fan pie, see plot
Optional, the default are the first [1:k] colors of the default color sequence used in this package, otherwise a character vector of [1:k] specifying the colors analog to plot
Optional, the radius of the pie in numerical numbers
Optional, further arguments passed on to plot

If Number of Slices is higher than MaxNumberOfSlices then ABCanalysis is applied (see [Ultsch/Lotsch, 2015]) and group A chosen.
If Number of Slices in group A is higher than MaxNumberOfSlices, then the most important ones out of group A are chosen.
If MaxNumberOfSlices is higher than Slices in group A, additional slices are shown depending on the percentage (from high to low).
Parameters of visualization a set as in [Schwabish, 2014] defined.
Color sequence is automatically shortened to the MaxNumberOfSlices used in the pie chart.
