Finding the elbow/knee in a curve

Question

I have these data:

x <- c(6.626,6.6234,6.6206,6.6008,6.5568,6.4953,6.4441,6.2186,6.0942,5.8833,5.702,5.4361,5.0501,4.744,4.1598,3.9318,3.4479,3.3462,3.108         


        

Answer 1

You can now find the knees/elbows with different methods by using the maxcurv function in the soilphysics package.
