determine_angles: Determine angles as seen by observer In triangulation: Determine Position of Observer

Description

Determine the angles (between three known points) as seen by an observer with a known position.

Usage

 ```1 2``` ```determine_angles(A, B, C, observer_position = c(0, 0), output_plot = TRUE, lines_in_plot = TRUE, angles_in_plot = TRUE, decimals_in_plot = 2) ```

Arguments

 `A` A point defined by a vector containing an x- and an y-coordinate `B` A point defined by a vector containing an x- and an y-coordinate `C` A point defined by a vector containing an x- and an y-coordinate `observer_position` A vector containing an x- and an y-coordinate `output_plot` Boolean variable indicating whether a plot should be created `lines_in_plot` Boolean variable indicating whether lines should be drawn in the plot `angles_in_plot` Boolean variable indicating whether the angles should be printet in the plot `decimals_in_plot` Integer indicating the number of decimals used

Value

The angles as seen by the observer expressed in radians.

Examples

 ```1 2 3 4``` ```determine_angles(A = c(0, 0), B = c(10, 0), C = c(5, 5), observer_position=c(4,1)) determine_angles(A = c(0, 0), B = c(10, 0), C = c(5, 5), observer_position=c(4,40), angles_in_plot = FALSE) ```
