How to do knn regression

ksmooth() will work for you, since you only have one predictor.  There are
better choices, though, such as loess().

How can I do a simple k nearest neighbor regression in R? My training
data have 1 predictor and 1 outcome, both are numeric. I also need to
use FPE and SC to find the optimal model. I know there is knn() in
class package, but it's for knn classification. I also find a kknn
package. What function should I use?

Thanks in advance!
