Recently I found this post which made me clear on the R Markdown vs. R Notebook issue. http://uc-r.github.io/r_notebook

Here are a few relevant lines:

Writing an R Notebook document is no different than writing an R Markdown document. The text and code chunk syntax does not differ from what you learned in the R Markdown tutorial. The primary difference is in the interativeness of an R Notebook. Primarily that when executing chunks in an R Markdown document, all the code is sent to the console at once, but in an R Notebook, only one line at a time is sent. This allows execution to stop if a line raises an error.

Also there is this on knit vs. preview when you create a R Notebook in RStudio:

The preview shows you a rendered HTML copy of the contents of the editor. Consequently, unlike Knit, Preview does not run any R code chunks. Instead, the output of the chunk when it was last run in the editor is displayed.

Hope you find it useful.
