Description

We already have support for code cells in R with syntax like this (similar to the Python support):


# %%
1 + 1

# %%
library(tidyverse)
diamonds |> 
  filter(carat > 2) |> 
  group_by(color) |> 
  summarise(price = median(price))

Let's consider adding additional, alternative syntax support in .R files for using the knitr::spin() support, as outlined:

Research direction

Read the linked Quarto and R Markdown references to understand the knitr::spin() syntax, then compare it with Positron's existing R and Python code-cell support. Add recognition for the alternative syntax in .R files while preserving the existing # %% form, and verify that both forms produce code cells as intended.
