##### Tabulation for Vectors

tabulate takes the integer-valued vector bin and counts the number of times each integer occurs in it.

Keywords

##### 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 64-bit platforms bin can have $2^31$ or more elements and hence a count could exceed the maximum integer: this is currently an error.
