CougarStats is an open-source platform-independent browser-based interface for statistical data analysis.
You can use the app on our website: https://www.cougarstats.ca/
or using our backup on Shinyapp.io server by clicking https://cougarstats.shinyapps.io/CougarStats/
Alternatively you can send a pull request to download all the files in this repository and run the app by loading global.R, ui.R, and server.R and clicking Run App. Note that the CougarStats project is not on CRAN, just on github.
CougarStats has also been Dockerized. You can pull the Docker image here by running:
docker pull mmyer/cougarstats:latest
then start the container:
docker run -dp 127.0.0.1:3838:3838 mmyer/cougarstats
and navigate to 127.0.0.1:3838 using a browser of your choice to access a copy of CougarStats running locally on your machine.
