Prepare for sorting and get range, number of NAs and unsortedness

Description

In one pass over the vector NAs are treated according to parameter na.last exactly like sort() does, the range(), number of NAs and unsortedness is determined.

Usage

range_sortna(x, decreasing = FALSE, na.last = NA)

Arguments

Value

an integer vector with NAs are treated and an attribute range_na() with four elements:

1. min integer

2. max integer

3. number of NAs

4. 0 for sorted vector and 1 for is.unsorted()

Examples

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