points2equation: Get a Slope–intercept Form from a Two-point Form of an Equation
Description
Two-point from is often seen in German national forest inventory data,
we want to get an equation of form
y = a + bx.
Usage
points2equation(p1, p2 = c(0, 0))
Value
A named vector with intercept ["a"] and slope ["b"].
If both points have the same value for x, no function exists. Then
the intercept is NA and the slope gives the value of x.
Arguments
p1
The first point (x, y).
p2
The second point (x, y).
