[R] rbind - names in dataframe. Beginner Question

[Sarah Goslee]

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.
