Jupyter R Sessions within CDSW
A number of customers want to run CDSW R sessions within the Jupyter Notebook. This is unsuccessful within CDSW when a customer attempts to perform this and results in the following errors depending on how you execute Jupyter.
Execution halted

By default the Jupyter R Kernel is not shipped with CDSW 1.5+. In order to get this to work you will have to install the Jupyter R Kernel manually. The instructions are below as follows:

Instructions on installing Jupyter R Kernel from source.
1/2) Installing from source
ZMQ
You'll need zmq development headers to compile pbdZMQ (Click your OS):
R packages
Start R in the same terminal, and proceed as below.
You can install the packages via
install.packages(c('repr', 'IRdisplay', 'IRkernel'), type = 'source')
To update your source installation, repeat above step.
2/2) Making the kernel available to Jupyter
The kernel spec can be installed for the current user with the following line from R:
IRkernel::installspec()
To install system-wide, set user to False in the installspec command:
IRkernel::installspec(user = FALSE)
