tabulate | R Documentation |
tabulate
takes the integer-valued vector bin
and counts
the number of times each integer occurs in it.
tabulate(bin, nbins = max(1, bin, na.rm = TRUE))
bin |
a numeric vector (of positive integers), or a factor. Long vectors are supported. |
nbins |
the number of bins to be used. |
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
.
An integer valued integer
or double
vector
(without names). There is a bin for each of the values 1,
..., nbins
; values outside that range and NA
s are (silently)
ignored.
On 64-bit platforms bin
can have 2^31 or more
elements (i.e., length(bin) > .Machine$integer.max
), and hence
a count could exceed the maximum integer. For this reason, the return
value is of type double for such long bin
vectors.
