is_parallel: Whether two objects are parallel

Description

is_parallel() is a S3 method that tests whether two objects are parallel.

Usage

is_parallel(x, y, ...)
# S3 method for Line2D
is_parallel(x, y, ..., tolerance = sqrt(.Machine$double.eps))
# S3 method for Plane3D
is_parallel(x, y, ..., tolerance = sqrt(.Machine$double.eps))

Value

A logical vector.

Arguments

x, y

The two objects to compute if they are parallel.

...

Passed to other methods (or ignored).

tolerance

Numerics with differences smaller than tolerance will be considered “equivalent”.

Examples

line1 <- as_line2d("x-axis")
line2 <- as_line2d("y-axis")
line3 <- as_line2d(a = 0, b = 1, c = 2) # y + 2 = 0
is_parallel(line1, line1)
is_parallel(line1, line2)
is_parallel(line1, line3)
