Examples

## load APA data set, full version
data(APAFULL)
## Emond and Mason Branch-and-Bound algorithm. 
## If the number of object is higher than 20, EMCons function may work for several minutes. 
## Use either QuickCons or FASTcons instead
CR=EMCons(APAFULL)
TR=tabulaterows(APAFULL)
CR2=FASTcons(TR$X,TR$Wk,maxiter=5)
CR3=QuickCons(TR$X,TR$Wk)
