How can I use splne() with ggplot?
- by David
I would like to fit my data using spline(y~x) but all of the examples that I can find use a spline with smoothing, e.g. lm(y~ns(x), df=_).
I want to use spline() specifically because I am using this to do the analysis represented by the plot that I am making.
Is there a simple way to use spline() in ggplot?
I have considered the hackish approach of fitting a line using
geom_smooth(aes(x=(spline(y~x)$x, y=spline(y~x)$y))
but I would prefer not to have to resort to this.
Thanks!
