Calculate arc tangent of a value in R programming – atan2(y, x) function

With the help of atan2(y, x) method, we can get the arc tangent between x axis and a vector from origin to (x, y) in R programming.

Syntax: atan2(y, x)
Return: Returns the arc tangent value.

Example 1:

x <- c(2, 3, 4)

# Using atan2(y, x) method
gfg <- atan2(1, x)

print(gfg)

Output:

[1] 0.4636476 0.3217506 0.2449787

Example 2:

x <- c(2, 3, 1)

# Using atan2(y, x) method
gfg <- atan2(pi/3, x)

print(gfg)

Output:

[1] 0.4823479 0.3358424 0.8084488
