How to count numbers of a vector and use them as index values?from Sabrina
Hi: Another possibility is
x <- c(2,2,3,3,4,6) tabulate(x, 8)
[1] 0 2 2 1 0 1 0 0 where the second argument of tabulate() allows one to specify the number of bins, in order from 1 up to the specified value, with all others outside that range ignored. HTH, Dennis On Thu, Aug 18, 2011 at 12:29 PM, Sabrina Friedman

Hi Paul, I would use something like this:

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 Sarah On Sun, Jul 31, 2011 at 5:41 PM, Paul Menzel <paulepanter at users.sourceforge.net> wrote:
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
