How to install R package "appnn"?

Question

I am trying to install R package appnn (link)

Based on Page 2 of its manual, I tried but could not find the function appnn.

I agree it is duplicate. Sorry for that, but should I delete this answer? I was warned when I try to delete it. — lanselibai, Feb 07 '18 at 22:09

You have successfully installed the package. To use the package you need to run

library(appnn)

for it to be attached to the search path. Then the functions will work as normal.

Note that you need to run library() everytime you start a fresh R session and want to use this package
