Jupyterhub r shiny support

[harshi...@gmail.com]

Hi All,

We have a use case to be able to use r shiny within jupyter notebook (using rpy2 magic in ipython kernel notebook) hosted on JupyterHub server. Based on our quick research, we noticed shiny package needs either an R Studio server or Shiny server to run the apps (server.r and ui.r files). Is this doable using notebooks either locally or on JupyterHub server?

 

A couple of questions regarding JupyterHub (JH):

• How do we use “Runapp()” or equivalent function to run shiny apps for multiple users on a single port in JH?
• As we are using Amazon Linux AMI, we don’t have a default browser installed and no GUI desktop. So how can we launch shiny apps without a web browser?

Please share any docs/links that might assist us or r shiny alternatives/interactive web framework packages which could be used in JupyterHub

Thanks!

There is a thread related to your question in the JupyterHub discourse
forum: https://discourse.jupyter.org/t/lifecycle-for-servers-started-by-jupyter-server-proxy/314
maybe that already helps and/or we can merge these threads?

I think what you are looking for is
https://github.com/jupyterhub/jupyter-rsession-proxy which is a
notebook server extension that lets you run RStudio and RShiny apps. A
demo of this is
https://github.com/binder-examples/r#specifying-an-r-environment-with-a-runtimetxt-file
which shows you how to install the extension and lets you try it out
on mybinder.org

Hope this helps,
T

@yuvipanda Made a number of changes (very) recently that you might want to try out. See (closed) issue linked below. As far as I know you can only run runApp() from Rstudio server but you can now start Rstudio directly from Jupyter by clicking on an icon.

Thank you Tim. Will check out these links. However was curious to know if using either jupyter-rsession-proxy or jupyter-server-proxy, can we run iPython notebooks including Python code as well as R Shiny applications (RunApp with dataframe inputs)? Or is this only relevant to R specific notebooks?

Thanks vnijs, will check these latest updates.

Hi All,

Wanted to check if Jupyter-rsession-proxy or Jupyter-server-proxy enables us to run Shiny applications from IPython (.ipynb) notebooks and not just R notebooks in Amazon Linux AMI instance? We need to embed Python code and R code (using R Magic) in .ipynb notebooks.

Thanks,

Harshith

There's an example in the Binder example repos of launching from Binderhub into a SHiny app:
