After running iterations of `lm()` in R, I am now stuck with which components of the model's output to present and how to present them. I know that the r-squared value, Co-efficients Plot and Intercept are of central importance. Is there any free resource which shows: how to interpret output, and then visually represent of model outputs,especially output from `R`. I read http://stats.stackexchange.com/questions/5135/interpretation-of-rs-lm-output but I find it difficult to translate that into what it means in my domain.
