If I'm reading this correctly, you want to add a column to your
dataframe with a name corresponding to the value in the Hunger column.
myframe <- data.frame (ID=c("Ernie", "Ernie", "Ernie", "Bert",
"Bert","Bert", "Duck"), Hunger=c(1,1,1,2,2,1,3) )
myframe$Hungertype <- c("none", "bighunger", "verybighunger")[myframe$Hunger]
ID Hunger Hungertype
1 Ernie 1 none
2 Ernie 1 none
3 Ernie 1 none
4 Bert 2 bighunger
5 Bert 2 bighunger
6 Bert 1 none
7 Duck 3 verybighunger
Then you can subset it to remove low values, sort it, etc.
