The 0 is the name of the item and the 1 is the index in f of the maximum class. (since f is a table, and the first element of the table is the maximum, which.max returns a 1) So, if you just want to know which class is maximum you can say

 names(which.max(f))

Subject: [R] request: a class having max frequency

Dear R users
I have a very basic question. I tried but could not find the required result. using
dat <- pima
f <- table(dat[,9])

> f

  0 1
500 268
i want to find that class say "0" having maximum frequency i.e 500. I used
>which.max(f)
which provide
0
1
How can i get only the "0". Thanks and

best regards
