Issues running R

I was trying to run R with script (Ubuntu 14.04; Atom 1.18), running the entire code and selection by block works. Some issues / questions:
1. when attempting to run by line number I become "Line Number Based runner not available for R.
If it should exist, add an issue on GitHub, or send your own pull request." ... is that so?
2. If I run two selected lines separately, and the first is a requisite for the second, I also become an error. I assume that each time I run a line is an independent process. Is there a way to keep the information generated when running previous lines?
3. Is it possible to have access to the complete log of results? In the lower pane it appears just the last one.

Thanks, -jc
