Returns the planar angle measured from the positive x‑axis toward the
positive y‑axis. By default the result is mapped to [0, 2π); setting
centered = TRUE leaves the native atan2 range [-π, π].
Usage
cartesian_to_phi(x, y, centered = FALSE)
Arguments
- x
numeric vector of x‑coordinates
- y
numeric vector of y‑coordinates
- centered
logical; if TRUE keep the [-π, π] range, otherwise map to [0, 2π\)
Value
numeric vector of azimuth angles (φ) in radians
