Compute the angle of a vector — vector_angle • WJSmisc

Compute the angle of a vector

Usage

vector_angle(x, origin = c(0, 0), degrees = FALSE, allow_negative = FALSE)

Arguments

x: A length-2 vector
origin: A length-2 vector
degrees: If TRUE, returns angles in degrees instead of radians
allow_negative: If TRUE, returns angles between -pi and pi (-180 and +180. If FALSE, returns angles between 0 and 2 * pi (0 and 360)

Value

A length-1 vector

Examples

vector_angle(c(1,1))
#> [1] 0.7853982
vector_angle(c(1,1), degrees = TRUE)
#> [1] 45
