Tabulation for Vectors
tabulate
takes the integervalued vector bin
and counts
the number of times each integer occurs in it.
 Keywords
 arith
Usage
tabulate(bin, nbins = max(1, bin, na.rm = TRUE))
Arguments
 bin
 a numeric vector (of positive integers), or a factor. Long vectors are supported.
 nbins
 the number of bins to be used.
Details
tabulate
is the workhorse for the table
function.
If bin
is a factor, its internal integer representation
is tabulated.
If the elements of bin
are numeric but not integers,
they are truncated by as.integer
.
Value

An integer vector (without names). There is a bin for each of the
values 1, ..., nbins; values outside that range and NAs
are (silently) ignored.On 64bit platforms bin can have 2^{31}2^31 or more
elements and hence a count could exceed the maximum integer: this is
currently an error.

Examples
library(base)
tabulate(c(2,3,5))
tabulate(c(2,3,3,5), nbins = 10)
tabulate(c(2,0,2,3,3,5)) # 2 and 0 are ignored
tabulate(c(2,0,2,3,3,5), nbins = 3)
tabulate(factor(letters[1:10]))
