Can I run a jupyter notebook with an R kernel from a jupyter notebook with a python kernel?

I have some R code to update a database stored in update_db.ipynb. When I try to %run update_db.ipynb from a jupyter notebook with a python kernel, I get an error

File "<ipython-input-8-815efb9473c5>", line 14
    city_weather <- function(start,end,airports){
                                                ^
SyntaxError: invalid syntax

Looks like it thinks that update_db.ipynb is written in python. Can I specify which kernel to use when I use %run?

Your error is not due to the kernel selected. Your command %run is made to run python only, but it has to be a script, not a notebook. You can check in details the ipython magic commands

For your use case I would suggest to install both python and R kernel in jupyter. Then you can use the magic cell command %%R to select to run R kernel for a cell inside the python notebook. Source :this great article on jupyter - tip 19

Other solution is to put your R code in an R script, and then execute it from a jupyter notebook. For this you can run a bash command from a jupyter notebook that will execute the script

!R path/to/script.r
