Description

Counts the number of elements in non-overlapping bins

Usage

Arguments

Details

binCounts(x, bx, right = TRUE) gives equivalent results as rev(binCounts(-x, bx = rev(-bx), right = FALSE)), but is faster and more memory efficient.

Value

Returns an integer vector of length B with non-negative integers.

Missing and non-finite values

Missing values in x are ignored/dropped. Missing values in bx are not allowed and gives an error.

An alternative for counting occurrences within bins is hist, e.g. hist(x, breaks = bx, plot = FALSE)$counts. That approach is ~30-60% slower than binCounts(..., right = TRUE).

To count occurrences of indices x (positive integers) in [1, B], use tabulate(x, nbins = B), where x does not have to be sorted first. For details, see tabulate().

To average values within bins, see binMeans().
