R 4.4.1

Describe the issue:

In Positron, my settings are as follows:

"editor.tabSize": 4,
"editor.insertSpaces": true,

When formatting the document, the code indents with two spaces. I also tried adding the following settings:

"[r]": {
    "editor.tabSize": 4,
    "editor.insertSpaces": true
}

However, after formatting the R document, the indentation remains at two characters. Is this a bug, or is there something wrong with my settings?

Steps to reproduce the issue:

When format R script.

Hi @dbcoffee! Which settings file are you updating? Could you include a screenshot of the entire file?

I was able to change the settings by doing the following:

1. Open up the Command Prompt (Ctrl + Shift + P or Cmd + Shift + P)
2. Search for Preferences: Open User Settings (JSON)
3. Add the following to the settings.json file that opens

       "[r]": {
           "editor.tabSize": 4,
           "editor.insertSpaces": true
       }

4. Save the settings.json file -- example of the entire file:

I have modified the user settings.json file. My settings JSON is as follows:

{
    "workbench.colorTheme": "GitHub Light Colorblind (Beta)",
    "editor.hover.delay": 0,
    "editor.hover.hidingDelay": 0,
    "window.openFilesInNewWindow": "on",
    "explorer.confirmDelete": false,
    "editor.formatOnPaste": true,
    "outline.showVariables": false,
    "outline.icons": false,
    "notebook.breadcrumbs.showCodeCells": false,
    "quarto.visualEditor.lineNumbers": true,
    "quarto.visualEditor.spelling": false,
    "notebook.outline.showCodeCellSymbols": false,
    "quarto.usePipQuarto": false,
    "Lingma.cloudModelAutoTriggerGenerateLength": "long",
    "Lingma.cloudModelManualTriggerGenerateLength": "long",
    "Lingma.cloudModelLanguagesOrFileExtensions": "",
    "outline.showFunctions": true,
    "outline.showMethods": false,
    "editor.rulers": [],
    "editor.guides.highlightActiveBracketPair": false,
    "editor.renderLineHighlight": "none",
    "editor.guides.indentation": false,
    "editor.occurrencesHighlight": "off",
    "positron.viewer.interactivePlotsInViewer": true,
    "application.experimental.positronPlotsInEditorTab": true,
    "positron.RemoteHostExperimental": true,
    "editor.formatOnType": true,
    "rstudio.keymap.enable": true,
    "positron.r.kernel.logLevel": "trace",
    "application.experimental.postitronPlotsInEditorTab": true,
    "[r]": {
        "editor.tabSize": 4,
        "editor.insertSpaces": true
    }
}

Despite these settings, when formatting R code (.r files), it still maintains a 2-space indentation instead of following the set 4-space indentation."

I can reproduce. I believe it's because we use the styler package with the default Tidyverse style guide config without propagating the VS Code formatting settings.

@dbcoffee This and many other issues will be fixed once we have switched Positron to use the new formatter we're developing: https://github.com/posit-dev/air
