In truecluster/bit: Classes and Methods for Fast Memory-Efficient Boolean Selections

Low-level sorting: bit sort

Description

In one pass over the vector NAs are handled according to parameter na.last by range_sortna, then, if the vector is unsorted, bit sort is invoked.

Usage

bitsort(x, na.last = NA, depth = 1)

Arguments

x	an integer vector
na.last	NA removes NAs, FALSE puts NAs at the beginning, TRUE puts NAs at the end
depth	an integer scalar giving the number of bit-passed before switching to quicksort

Value

a sorted vector

Examples

bitsort(c(2L,0L,1L,NA,2L))
bitsort(c(2L,0L,1L,NA,2L), na.last=TRUE)
bitsort(c(2L,0L,1L,NA,2L), na.last=FALSE)
