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).

getpolar(n0, n1, ...)

## S4 method for signature 'numeric,numeric'
getpolar(n0 = c(0, 0), n1, ...)

## S4 method for signature 'Node,Node'
getpolar(n0, n1, ...)

`n0`	an object of class `numeric` with a length of 2 (x/y-coordinates) or a class derived from `Node`. Used as origin.
`n1`	an object of class `numeric` with a length of 2 (x/y-coordinates) or a class derived from `Node`.
`...`	see Optional Values

the angle as a value of class numeric.

Optional Parameters (`...`)

used by getpolar

nonnegative: optional logical. Indicating if 2pi should be added to negative values. Default is TRUE
deg: optional logical. Indicating if the result should be converted to degrees. Default is FALSE
log: optional logical. Indicating if the calculations should be logged. Default is FALSE
offset: optional numeric. Should be when using rotated coordinate systems. Default is 0. Has to be provided in RADIANS!
