Closest fit data to a particular formula

Here is my current loess line code: mg.lo = loess(y ~ x, mg, span=0.25) mg$x_c <- predict(mg.lo) which produces a curve like the attached file loess_curve.png. and I would like to have a curve "something like" the arccot in the attached file arccotangent.png (from wikipedia), but all x values are positive - meaning just the best fit of the sample data to that type of curve.. starts high and finishes low but doesn't go below zero and only decreases. Looking at the arccot(x) definition I can see it as: arccot x = pi/2 - atan(x) So I tried t...
