Bin a Numeric Vector
Bin a numeric vector and return integer codes for the binning.
.bincode(x, breaks, right = TRUE, include.lowest = FALSE)
- a numeric vector which is to be converted to integer codes by binning.
- a numeric vector of two or more cut points, sorted in increasing order.
- logical, indicating if the intervals should be closed on the right (and open on the left) or vice versa.
- logical, indicating if an x[i] equal to
the lowest (or highest, for
right = FALSE) breaks value should be included in the first (or last) bin.
This is a barebones version of
FALSE) intended for use in other functions which have checked the
arguments passed. (Note the different order of the arguments they have
breaks do not need to be unique.
An input can only fall into a zero-length interval if it is closed
at both ends, so only if
include.lowest = TRUE and it is the
first (or last for
right = FALSE) interval.
An integer vector of the same length as x indicating which bin
each element falls into (the leftmost bin being bin 1).
NaN and NA elements of x are mapped to
NA codes, as are values outside range of breaks.
## An example with non-unique breaks: x <- c(0, 0.01, 0.5, 0.99, 1) b <- c(0, 0, 1, 1) .bincode(x, b, TRUE) .bincode(x, b, FALSE) .bincode(x, b, TRUE, TRUE) .bincode(x, b, FALSE, TRUE)
