IMPORTANT: the latest version of editR (>=0.2) has undergone important modifications (see release notes below). The most important changes are the following:

- editR is now fully compatible with the latest version of shiny on CRAN (>=0.11). editR was modified to support Twitter Bootstrap version 3 instead of version 2 as in the previous releases.

- editR now relies (almost) entirely on packages available through CRAN and not on a large number of experimental packages as previously. This will facilitate the installation process.

As a consequence of these modifications I strongly recommend that you reinstall editR following the new instructions below.

Release notes

editR is a basic Rmarkdown editor with instant previewing of your document. It allows you to create and edit Rmarkdown documents while instantly previewing the result of your writing and coding. It also allows you to render your Rmarkdown file in any format permitted by the rmarkdown R package.

Installing editR from this GitHub repository is now pretty straightforward. Simply copying the following lines of code in your R terminal should to install everything you need to run editR on your computer:

if (!require("devtools")) install.packages("devtools")


editR requires the installation of the latest versions of following packages on CRAN:

  1. shiny
  2. shinyFiles
  3. shinyBS
  4. rmarkdown
  5. knitr

It also requires the installation of the development version of the following package on GitHub:

  1. shinyAce

Finally, to render documents in various output formats (.html, .pdf, .docx), editR uses the render function from the rmarkdown package. This function requires the installation of pandoc to work. Installation instructions for pandoc can be found at: For Mac users, I recommend that you install pandoc via Homebrew or MacPorts.


To start editR, simply run this line of code in your R console:


with "path/to/file.Rmd" the path to a new or existing .Rmd (or .md) file. If this is a new file, it will be created at this location. You can also open an existing file from within editR using the File > Open file menu.

You can also open editR without providing a path to a new or existing .Rmd file.


In this case a temporary new file will be created that can then be saved from withing the user interface of editR.
