[holgerbrandl]

That's an easy one. There are different rendering backends. See https://github.com/holgerbrandl/kravis#rendering

You are using the local r backend, but you don't have r installed.

I'm using Datalore (IPython kernel in kotlin) and datascience isn't my background, how may I fix it?

[holgerbrandl]

Oh, I think since datalore is a hosted Sodas product there is no fix, unless the vendor does install r or enables support for a different kravis rendering backend

[elect86]

Oh pity

Ok thanks for the info
