Get angle from origin to vector of x,y coordinates
xyAngle(
x,
y = NULL,
directed = FALSE,
deg = TRUE,
origin.x = 0,
origin.y = 0,
...
)numeric vector or two-column matrix with columns
representing x,y coordinates when y is NULL.
numeric vector or NULL.
logical indicating whether to return angles around
the full circle, or only half circle. For example, in degrees
c(1,1) indicates 45 degrees, c(-1,-1) indicates -135 degrees.
When directed=FALSE then c(-1,-1) indicates 45 degrees.
logical indicating whether to return degrees, or when
deg=FALSE it returns radians.
numeric input defining the coordinates to use as the origin. When non-zero it implies the first point of each segment.
additional arguments are ignored.
This function gets the angle from origin to x,y coordinates, allowing for vectorized input and output.
