trackdown - R package for improving collaborative writing

Project Status: Active – The project has reached a stable, usable state and is being actively developed. CRANstatus R-CMD-check codecov DOI


The trackdown package offers a simple solution for collaborative writing and editing of R Markdown (or Sweave) documents. Using trackdown, the local .Rmd (or .Rnw) file can be uploaded as a plain-text file to Google Drive. By taking advantage of the easily readable Markdown (or LaTeX) syntax and the well-known online interface offered by Google Docs, collaborators can easily contribute to the writing and editing process. After integrating all authors’ contributions, the final document can be downloaded and rendered locally.


You can install the released version from CRAN with:


To install the development version from GitHub, run the following code:

# install.packages("remotes")
                         build_vignettes = TRUE)

The trackdown Workflow

During the collaborative writing/editing of an .Rmd (or .Rnw) document, it is important to employ different workflows for computer code and narrative text:

Thus, the workflow’s main idea is simple: Upload the .Rmd (or .Rnw) document to Google Drive to collaboratively write/edit the narrative text in Google Docs; download the document locally to continue working on the code while harnessing the power of Git for version control and collaboration. This iterative process of uploading to and downloading from Google Drive continues until the desired results are obtained. The workflow can be summarized as:

Collaborative code writing using Git & collaborative writing of narrative text using Google Docs


trackdown offers different functions to manage the workflow:

Special Features

trackdown offers additional features to facilitate the collaborative writing and editing of documents in Google Docs. In particular, it is possible to:

Advantages of Google Docs

Google Docs offers users a familiar, intuitive, and free web-based interface that allows multiple users to simultaneously write/edit the same document. In Google Docs it is possible to:

Moreover, Google Docs allows anyone to contribute to the writing/editing of the document. No programming experience is required, users can just focus on writing/editing the narrative text.

Note that not all collaborators have to have a Google account (although this is recommended to utilize all Google Docs features). Only the person who manages the trackdown workflow needs to have a Google account to upload files to Google Drive. Other collaborators can be invited to contribute to the document using a shared link (See Instructions).
