Usage

1
ABCRemoveSmallYields(Data,CumSumSmallestPercentage)

Arguments

Data

vector[1:n] describes an array of data: n cases in rows of one variable

(default =0.5),the smallest data up to a cumulated sum of less than CumSumSmallestPercentage

Details

Data <0 are set to zero, non-numeric values (NA,NaN,etc.) in Data are set to zero strings and chars are set to zero infinitive numbers are set to max(Data) the smallest data up to a cumulated sum of less than CumSumSmallestPercentage of the total sum (yield) is removed
