我如何要求R从用户定义的程序包运行特定功能以在每次加载该程序包时运行？

Question

I've created a package mypack with only one r script in the R directory of the project, hello.R which basically prints our Hello World when loaded and run. Now i need to add some lines of code to a script (ex- hide.R ) so that the contents of the function hello.R is not easily visible to a not so experience user. I need this hide.R to run first each time the package mypack is loaded. Can somebody give me a full working example for this?

Note: outside a package, if I have a function foo, then the following makes it a little difficult for a normal user to get the function definition easily

srcfile <- srcfilecopy("", "Don't cheat")
srcref <- srcref(srcfile, c(1,1,1,12))
attr(foo, "srcref") <- srcref

Ultimately, once a user loads my package, he/she should not be easily able to get the contents of my function inside the package by typing out the function name. This is for educational purposes.

You can define a function called .onLoad inside your package. See docs here: https://stat.ethz.ch/R-manual/R-devel/library/base/html/ns-hooks.html
