How to count numbers of a vector and use them as index values?

Hi Paul,

I would use something like this:

x <- c(2,2,3,3,4,6)
table(x)

x
2 3 4 6
2 2 1 1

x <- factor(x, levels=1:8)
table(x)

x
1 2 3 4 5 6 7 8
0 2 2 1 0 1 0 0

Dear R folks,


I am sorry to ask this simple question, but my search for the right
way/command was unsuccessful.

I have a vector

x <- c(2, 2, 3, 3, 4, 6)

Now the values of x should be considered the index of another vector
with possible greater length, say 8, and the value should be how often
the indexes appeared in the original vector x.

length(result)

?[1] 8

result

?[1] 0 2 2 1 0 1 0 0


Thank you in advance,

Paul
