Google's coding standards for R - SmartData Collective

For any software application in production and produced by a development team, coding standards are an essential tool for promoting maintainability and quality. Google has recently published their coding standards for R, with a compendium of common-sense tips for keeping an R project in shape. The standards Google R programmers adhere to include:

File Names: end in .R
Identifiers: variable.name, FunctionName, kConstantName
Line Length: maximum 80 characters
Indentation: two spaces, no tabs
Curly Braces: first on same line, last on own line
Assignment: use <>, not =
Semicolons: don’t use them
Commenting Guidelines: all comments begin with # followed by a space; inline comments need two spaces before the #
