[Bug]: indentation clash (formatter vs lintr) #1883

Area

Syntax highlighting

Bug description

VS Code indents with 4 spaces by default, and vscode-R doesn't override this for R. However, lintr expects indentation of 2 spaces. This leads to a harmless, but annoying linting markup for any new R file:

Steps to reproduce

Open a new file and type and write some code with indentation, e.g. a function call over multiple lines:

plot(
    1:10
)

Again, the 4 spaces is what gets produced automatically. But lintr will complain that it should only be 2.

 [indentation_linter] Indentation should be 2 spaces but is 4 spaces.

Expected behavior

The indentation behaviour or vscode-R should accord with its default linter. My own preference is for that to be 2 spaces, which is the standard that most R linters follow (incl. lintr, air, etc.)

We could set this part of the r block in configurationDefaults.

"[r]": {
    "editor.tabSize": 2
  }

Environment

vscode-R: 3.2.0
R: 4.6.1
