Count Entries in Bins
DESCRIPTION:
Counts the number of occurrences of integers.
USAGE: 
tabulate(bin, nbins = max(bin))
REQUIRED ARGUMENTS:
bin:
vector of bin numbers, between 1 and nbins, inclusive. A category is appropriate for bin. Missing values are not accepted.
OPTIONAL ARGUMENTS:
nbins:
maximum number of bins, at least as large as max(bin).
VALUE:
vector of length nbins. The ith element of the value counts the number of is that occurred in bin.
DETAILS:
Takes a vector, bin, and returns a vector of length nbins. For each element, i, counts the number of is that occurred in bin.
SEE ALSO:
category , hist , table .
EXAMPLES: 
tabulate(cut(lottery.payoff,10),10)


x <- c(1,2,3,4,5,5,6,6,7,8)
tabulate(x)
[1] 1 1 1 1 2 2 1


tabulate(x,15)
[1] 1 1 1 1 2 2 1 1 0 0 0 0 0 0 0
