Especially when working with long RMarkdowns (e.g. 2-3000+ lines), it is desirable to completely clear all rendering and output (i.e. to get back to the same state as though none of the code in the RMarkdown had ever been executed), except without necessarily clearing the environment.
Is there a way to do this?
Note: in case someone wonders why, here are a couple of reasons:
- occasionally (especially with javascript-heavy renderings, e.g. plotly, wordcloud etc) there can occasionally be bugs which not only affect the rendering that contains the bug, but all other renderings in the document, and
- particularly in long Rmd files, it is sometimes simply easier to scroll through a doc which hasn't got renderings in it.
