Or, you may use this approach:
> attach(achtergrond)
> spits <- ifelse(uurenminuut >= 5.30 & uurenminuut < 9.30, "morning",
+ ifelse(uurenminuut >=16.30 & uurenminuut < 19.0, "evening",
+ "between"))
> table(spits)

You can do this in 2 steps - have cut() make a factor with a different
level for each time period
then use levels<-() to merge some of the levels.
> z <- cut(.5:3.5, breaks=c(0,1,2,3,4), labels=c("0-1", "1-2", "2-3",
"3-4"))
> levels(z)
[1] "0-1" "1-2" "2-3" "3-4"
> levels(z) <- c("betw
