anglePoint {dagR} | R Documentation |
A function calculating the coordinates of the point that is at
a specific radian angle in a specific distance from a source point.
Internally called by smoothArc
.
anglePoint(A, angl, len)
A |
Vector of length two with the coordinates of the source point. |
angl |
Radian angle indicating into which direction the new point is to be calculated. |
len |
The distance at which the new point is situated from the source point. |
A vector of length two with the coordinates of the new point.
Another pretty superfluous helper function...
