sorted_union: Sorted Union

In andreas50/uts: Unevenly-spaced Time Series

Description

For two sorted numeric vectors a and b, determine the sorted union of unique elements.

Usage

sorted_union(a, b, tolerance = 0)

Arguments

a	a sorted vector of numbers.
b	a sorted vector of numbers.
tolerance	a non-negative number, indicating the tolerance for numerical noise. Specifically, numbers in a and b are appended one by one and in the appropriate order to the output vector. However, a number is only added if it is more than tolerance larger than the most recently added number.

Value

A numeric vector.

Examples

sorted_union(1:3, 2:4)

# Numerical noise < tolerance has no effect
sorted_union(0, 1e-14)
sorted_union(0, 1e-14, tolerance=1e-12)
sorted_union(c(0, 1e-14), 2, tolerance=1e-12)

# Trivial cases
sorted_union(1:10, c())
sorted_union(c(), 1:10)
sorted_union(c(), c())
