I spent too many years doing what you say you are 
doing because creating a package seemed quite 
complicated. Once I took the plunge I found it 
well worth the effort. You do have to invest time and effort to begin with.

You will find
?package.skeleton
?prompt
rewarding reading as well as those sections of 
the R extensions document which are relevant to your use.

Good luck
