I use emacs and (ess) for editing and running R. Getting started, I recommend Rstudio. It provides a window for a code file (save it), others for plots, help, files, ...
As you get more proficient, I'll want you to try Sweave, a process for combining R code, output, and plots into a nice report using LaTeX.

Significance stars in R output are outlawed! Use this option:

  options(show.signif.stars =FALSE)

or store it in a .First file which R runs when started in this directory

.First <- function(){
  options(show.signif.stars =FALSE)
}
save.image()

Or put the options into a text file called .Rprofile in the startup directory.
Use getwd() to see where that is.
