I created an enviroment for R in Anaconda Navigator and form there I launched Jupyter Notebook and opened the file I want to program in. And then I chose the kernel for R.
But I get a red warning sign at the top saying: Kernel Error.
Once I click on it I read this:

So I assume I have deleted the file in question. Can you help me fix this error?
