Possibilities: If you believe You'll need a Digital assignment operator, and understand why that’s deeply problematic, don’t contact it operator=. Enable it to be a named perform like virtual void assign(const Foo&).
Code-sensible, it looks like you’re grabbing a worth from a list or information frame, however you’re essentially examining a reactive benefit. No want to put in writing code to observe when inputs modify–just write reactive expression that read the inputs they want, and let Shiny handle knowing when to contact them.
Flag goto. Much better however flag all gotos that don't jump from a nested loop for the statement promptly after a nest of loops.
Statements Handle the circulation of control (apart from purpose calls and exception throws, which might be expressions).

A number of superb code editors can be obtained that offer functionalities like R syntax highlighting, automobile code indenting and utilities to mail code/functions for the R console.
