No r-kernel notebook named index.ipynb present

[fomightez]

The link next to 'Jupyter+R' on the README page tries to open index.ipynb which will have the R kernel setting; however, there is no such notebook present in this repository at this time.

To open it to the classic Jupyter notebook dashboard it could be changed to http://mybinder.org/v2/gh/binder-examples/r-conda/master?urlpath=%2Ftree%2F:

http://mybinder.org/v2/gh/binder-examples/r-conda/master?urlpath=%2Ftree%2F

Work-around from launches with the 'Jupyter + R' launch badge for now:

At this time, those trying to use the 'Jupyter + R' launch badge from the README page will end up at a 404 error page because of the 'dead-end' URL endpoint above. The session can still be used though by switching to JupyterLab or Jupyter Notebook by editing the end of the URL in the session that starts.

For example, you may see something like the following with a 404 error page when the session starts:

https://hub.2i2c.mybinder.org/user/binder-examples-r-conda-e6gf4rjb/tree/index.ipynb

Just edit the end of the URL to remove the tree/index.ipynb part and replace it with lab. Hit enter after you edit the URL and the page should reload and take you into JupyterLab.

Instead of lab use tree as the replacement to go to Jupyter Notebook 7 at this time.
