Description Usage Arguments Value Optional Parameters (...) Author(s) References Examples
This function calculates the angle of a vector defined by two points in radians. Optionally it can be converted to degrees. For the use of the Operations-Research-Sweep-Algorithm an offset angle can be set. It's als possible return positive values only (2pi will be added).
