Hello everyone,

I have the following factor:

levels(pp_income)
 [1] ""       "1"      "2"      "3"      "4"      "5"      "6"      "7"
 [9] "8"      "9"      "Renter"

I want to subset so that only values 1:9 are included. I have the following:

> income<-pp_income[pp_income %in% c(1:9)]
>
> levels(income)
 [1] ""       "1"      "2"      "3"      "4"      "5"      "6"      "7"
 [9] "8"      "9"      "Renter"

Why is this not working and can someone please suggest a solution?

Thank you!

Dan
