when I create a basic plot in R notebook it shows the graph right down at the code. and so does any table and other stuff too... which is cool but after I have seen it and I want to remove it. Is there a keyboard shortcut to do the same.
and if you have any other handy shortcuts specially for R Notebook.
Try Tools > Modify Keyboard Shortcuts… and then search for "chunk" and also "notebook" in the search box. There are lots of possible hooks that you can set your own shortcuts for. I believe the one you're thinking of is "Notebook Clear Output".
Thanks it worked like magic.
with just these 3 controls I will be able to control the flow of notebooks.
You have the power!
