I appreciate everyone's response. I will look at the options found in stack overflow.
My issue is that i'm trying to load a file (.csv) relative to the R file. I pass the directory structure around but that directory structure may be put into something I'm unaware of. If packages can solve this problem, that would be the right approach. Any direction in regards to this?
