Only your pdf attachment made it through. You would need to follow the Posting Guide regarding file types to achieve successful transmission.
I will say that open-ended debugging of your code does not fit the Posting Guide recommendations either... this is an R language mailing list, not a research assistance mailing list. It might fit in better at stats.stackexchange.com, but even they want a focused question rather than general assistance requests.
