Above piece of code produces errors
> xis=sort(xi,decreasing=TRUE)
Error in sort(xi, decreasing = TRUE) : object 'xi' not
found> plot(xi,fm)
Error in plot(xi, fm) : object 'xi' not found> polygon(c(xi,xis),c(f05m,f95m))
Error in xy.coords(x, y) : object 'f05m' not

Recently there was a threads about shading between 2 lines and se interval
for prediction. And also in help page ?predict.lm you can find a code for
plotting prediction interval for linear model
