Tabulation for Vectors
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))
- a numeric vector (of positive integers), or a factor. Long vectors are supported.
- the number of bins to be used.
tabulate is the workhorse for the
bin is a factor, its internal integer representation
If the elements of
bin are numeric but not integers,
they are truncated by
An integer vector (without names). There is a bin for each of the
1, ..., nbins; values outside that range and
NAs are (silently) ignored.On 64-bit platforms
bincan 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]))
