I'd like to fix a package, but can't figure out how to edit it. I can download the source from R-Forge as a .tar.gz and unzip it. There is an "R" directory with the source and also a "tests" directory.
How do I include the sources in my own project to test my edits?
How do I run the tests? The tests each start with "library(blotter)". How do I make that load the library from the sources I've downloaded.
