Description

I can't get Hydrogen to run any R code within Atom. The code is there, I hit Shift+Enter, and it just advances to the next line without running anything. Occasionally (but not always), it will give this error:

[IPKernelApp] ERROR | Invalid Message Traceback (most recent call last): 
File "C:\Users\tcapu\Anaconda3\lib\site-packages\ipykernel\kernelbase.py", line 234, in dispatch_shell msg = self.session.deserialize(msg, content=True, copy=False) 
File "C:\Users\tcapu\Anaconda3\lib\site-packages\jupyter_client\session.py", line 923, in deserialize raise ValueError("Invalid Signature: %r" % signature)

Steps to Reproduce

1. Install Anaconda3.7, Atom 1.39.1, and Hydrogen
2. Run IRkernel::installspec() in R
3. Attempt to run any R code in Atom

From the nteract.io docs to install IRKernel:

install.packages(c('repr', 'IRdisplay', 'evaluate', 'crayon', 'pbdZMQ', 'devtools', 'uuid', 'digest'))
devtools::install_github('IRkernel/IRkernel')
IRkernel::installspec()

You may potentially be able to use steps from https://irkernel.github.io/installation, but we can't guarantee that.

After further review, this could be an issue unrelated to your installation, but I am unsure of a root cause.

I saw this issue report recently with #1237, but am unsure how your workflow relates to the same issue still

Same issue. Clean install and have similar symptoms. R kernel is detected by hydrogen on launch of atom and listed in popup dialog, but no code execution occurs. I don't get the error that the user does which appears to be related to the Python kernel and not R, but just don't get any execution.

Have language-r grammar installed.

jupyter kernelspec list

shows the ir kernel as present and available, reinforcing that atom is able to detect.
