Re: [R] define stuff to be only usable in the same file
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..

You just do: tach(foo.R) and anything defined in foo.R will be usable but not visible when you do ls(). If you edit and save foo.R then just do retach() to rescan all the .R files you might have tached earlier. Stuff in your ls() environment can mask stuff attached via tach, so watch out for that.

Thanks Barry, that helped a lot, modified it a bit and it does pretty much what i wanted.

[R] define stuff to be only usable in the same file
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. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
