Is this from your source directory?  You shouldn't have the Built and 
Packaged lines in your source.

If this is from the directory where it was installed, never mind, unless 
those two directories are the same:  in which case the advice is "don't 
do that".  Keep your installed copies separate from the source.

The error message you saw

> Error in library("btRRTest") : 'btRRTest' is not a valid package -- 
> installed < 2.0.0?

indicates that the "Meta/package.rds" file is missing from your 
installed package subdirectory, but it's hard to guess why.
