Examples

event_stream <- data.frame(product=c("P45","P134","P45","P134","P134","P45","P134"),
                           sales=c(2,12,18,16,18,24,8),
                           alert=c(NA,NA,NA,NA,NA,"Alert P45","Alert P134"))
pc <- HSC_PC_Attribute("sales")
cons_stream <- classify(pc,event_stream)
