ABCRemoveSmallYields {ABCanalysis} | R Documentation |
Only the first column of Data is used, anything not beeing positive numerical value is set to zero
ABCRemoveSmallYields(Data,CumSumSmallestPercentage)
Data |
vector[1:n] describes an array of data: n cases in rows of one variable |
CumSumSmallestPercentage |
(default =0.5),the smallest data up to a cumulated sum of less than CumSumSmallestPercentage |
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
Output is of type list which's parts are described in the following
SubstantialData |
columnvector containing Data>=0 and zeros for all NaN and negative values in Data(1:n) |
Data2CleanInd |
Index such that SubstantialData = nantozero(Data(Data2SubstantialInd)) |
RemovedInd |
Data(RemovedInd) is the data that has been removed |
