Hi,
I'm completely new to R and am struggling with producing residuals from a
lowess curve. I have looked at the pdf help pages and searched online and have
tried the following code:
> l.agebl <- lines(lowess(agebl, f=.5))
> resid(l.agebl)
> resid(lowess(agebl, f=.5))
NULL
> residuals(lowess(agebl, f=.5))
NULL
AND
> r<-bl[order(age)]-lowess(agebl)$bl
> r
numeric(0)
> l<-lowess(agebl)
> r<-bl[order(age)]-l$bl
> r
numeric(0)
AND
> r<-residuals(lowess(bl~age))
> r
NULL
with no luck. Does anyone have any coding suggestions?
