**This OSF project is intended to enable the reproduction of the statistical analyses and the generation of the data figures of the virtual time project.**

**About the directories**
- You can find the code to reproduce the analyses in the folder called ```virtem_code```.
- Data used for the analyses are stored in the folder called ```data_for_analysis```.
**Instructions**
- Download virtem_public and its contents.
- Open the R project (```virtem_public.Rproj```) in R Studio. Your working directory should be the virtem_public folder.
- Run the R-script ```virtem_master_public.R``` that you can find in the folder ```virtem_code```. It will create a custom library folder in which it will attempt to install the necessary packages from CRAN and GitHub. Note that package installation may require user input, so you might have to run the master script line by line.
- The script will then start the analyses via the ```bookdown::render_book command```, which will execute the different RMarkdown scripts contained in the code folder. If all packages are installed correctly, the code should run without problems on different platforms. Installation can take around 1h.
**Expected Output**
- Statistical analyses reported in the manuscript and the corresponding figures will be reproduced. Expected runtime is around 2h.
- To document the results, HTML files are written to ```/virtem_public/virtem_code/docs```, which provide an overview of the code and any results/figures that are generated. Figures will be saved in ```/virtem_public/figures```.
**System Requirements**
- You will need to have installed a recent version of R and RStudio. The code has been tested using:
- Ubuntu 18.04.5 LTS running R version 3.6.1 (2019-07-05)
- macOS Catalina 10.15.7 running R version 4.1.0 (2021-05-18)
- Windows 10 x64 running R version 4.0.5 (2021-03-31)
- A list of all packages used is in the master script. For version numbers used in analyses underlying the main manuscript see https://jacbel.github.io/virtem_code/credit.html#session-info
- You will need around ~1.7 GB of free disk space
- No non-standard hardware is required
