Feature Request: Implement Output Insertion as Comments for Evaluated R Code

Title: Feature Request: Implement Output Insertion as Comments for Evaluated R Code

Description:

I propose adding a feature to vscode-R that allows users to evaluate selected R code and automatically insert the output as comments in the editor. This feature, inspired by a similar functionality in Nvim-R, would enhance the data analysis workflow by allowing immediate inspection and documentation of code outputs within the editor.

Reference:

• https://github.com/jalvesaq/Nvim-R/blob/5f3876a53fdceae4ee6c022bf94d24ca3d6bc1a2/doc/Nvim-R.txt#L378
• https://github.com/jalvesaq/Nvim-R/blob/5f3876a53fdceae4ee6c022bf94d24ca3d6bc1a2/R/start_r.vim#L827

Key Points:

• Select and evaluate R code in the editor.
• Capture the output and insert it as a comment directly below the evaluated code.
• Useful for iterative exploration and documentation in data analysis.

Implementation Suggestion:

• Extend existing 'send code to terminal' functionality.
• Add a method to capture terminal output and format it as a comment in the editor.

Impact:
This feature would streamline the R coding process in VS Code, making it more efficient for data analysis and similar tasks.

Start by tracing the existing “send code to terminal” functionality in the vscode-R extension and review the linked Nvim-R documentation and implementation for expected behavior. The feature is done when selected R code can be evaluated, its output captured, and that output inserted as comments directly below the code in the editor.
