Interleave origin and destination coordinates

Source: R/od-funs.R

This function takes a matrix with 4 columns representing origin and destination coordinates and returns a data frame with 3 columns with the ID of each linestring, plus the coordinates representing origin and destination coordinates. Essentially the function is a pivot, converting from wide to long format, to feed into other functions for creating geographic desire lines.
