Find the location of the maximum of a smoothing spline
Usage
findSplineMax(x, y, n = 1000, spar = NULL)
Arguments
- x
Numeric vector of x values.
- y
Numeric vector of y values (same length as x).
- n
Integer, number of grid points to evaluate (default 1000).
- spar
Smoothing parameter passed to stats::smooth.spline.
Value
A named list with components:
- x
The x coordinate at which the spline reaches its maximum.
- y
The corresponding maximum fitted y value.
Examples
x <- seq_len(10)
y <- sin(x) + rnorm(10, 0, 0.1)
findSplineMax(x, y)
#> $x
#> [1] 7.963964
#>
#> $y
#> [1] 1.15936
#>
