Try instead:
Age1<- cut(desc$Age, breaks = c(-Inf, 20,30,40,Inf),labels =
c("Low","Mid","Top"))
Do note that values that are <= 20 will be in the lowest category. (You wrote
only <20 whereas values of 20 would have not been in any interval.) The cut
function also has a use.lowest argument, whose actions I don't fully understand
but I usually set to to TRUE whereas is default is FALSE. I prefer the
Hmisc::cut2 functions because its defaults mirror my usual interests. Like
cut2, the findInterval function has closed intervals on the left.
