seeking a solution for both Python and R user..

[harryprince]

I am both using Python and R, can I see any solution to describe the python dependancies like R? or how I can contribute for that?

And I fail to find how to change the default CRAN repo mirror. I just wanna set the mirror as https://mirrors.tuna.tsinghua.edu.cn/CRAN/

probably pass as an environment variable with -e parameter in docker is a good solution.

Currently, we do not have plans for supporting package management systems for languages other than R, but that could be an idea to consider.

So, please declare them as system dependencies if they could be installed via apt-get. Another possibility is installing them on-the-fly in R Markdown code chunks since knitr supports that.

@harryprince - now this should be fixed by e332619.

The new include field allows users to include any custom Dockerfile snippets.
