Code linting - REditorSupport/vscode-R GitHub Wiki

R code linting (diagnostics) is provided by lintr via language server and is enabled by default.

To disable diagnostics, you might add the following to the VS Code settings:

{
  "r.lsp.diagnostics": false
}

However, you will not be notified if syntax errors in the code are detected.

To customize the linting behavior, edit the global lintr config file at ~/.lintr, or project-specific lintr config file at ${workspaceFolder}/.lintr.

The following are some examples:

• Only detect syntax errors:

linters: list()

• Deviate from default linters:

Adjust the number of characters in each line for line_length_linter and disable commented_code_linter.

linters: linters_with_defaults(
    line_length_linter(120), 
    commented_code_linter = NULL
  )

• Only use specified linters:

linters: list(
  commas_linter(),
  duplicate_argument_linter(),
  missing_argument_linter(),
  missing_package_linter(),
  namespace_linter())
