tabulate {base} | 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 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 and hence a count could exceed the maximum integer: this is
currently an error.
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]))
