Hello R-Help! I've looked around and have not found: A simple(short) way to hide functions and variables from the global environment. What i want is for a few of them to only be accessable from the scriptfile they're in. I probably could do fun things with environments , but that seems quite a hassle. As example: I have a file that gets me stuff from the database and creates an R object from the results, plus some functions on that object. Now i want the objectrelated stuff to be global, while the functions and variables i use for accessing the database shall be hidden.
define stuff to be only usable in the same file

The simplest and best way to do this is to write a package. You can also use local() around the code in a script, but it gets messy when you want to export more than one thing. Duncan Murdoch

After an hour i can say it is neither simple nor short nor will it work at all at the moment ERROR cannot change to directory 'testpack' -> tried to use the build command from pretty much everywhere
Forget about that, i'm stupid and can't use the tools available...

I think local isn't quite what i imagined.

Packaging ist still too complicated for my level i guess, can't get it to work properly, and it seems a lot of work. However apparently putting a "." in front of functions will hide them, saw that in another script, don't know what its about, but it works, so who cares..
