Hi Jim,
I am gettng the error message that the breaks are not unique: (R 2.15)
table(cut(Prices,breaks=Bands))
Error in cut.default(Prices, breaks = Bands) : 'breaks' are not unique
So, I tried using:
res<-rbind(as.data.frame(table(cut(Prices,breaks=seq1))),as.data.frame(table(cut(Prices,breaks=seq2))))
res2<-apply(res,2,function(x) gsub("\\(|\\]","",gsub("[,]","-",x)))
res3<-within(as.data.frame(res2),{Freq<-as.numeric(Freq)})
head(res3)
# Var1 Freq
#1 0-5 1
#2 5-10 6
#3 10-15 2
#4 15-20 2
#5 20-25 6
#6 25-30 2
A.K.
