Are there any official naming conventions for R?

Question

Most programming languages have official naming conventions for functions, parameters, classes, etc. Official here means that the conventions are issued by the organization behind the language.

Are there any official naming conventions for R?

I'm aware that naming conventions and R have been discussed before on stackoverflow, but that was some time ago and my question is not "what naming convention do you prefer?" but rather concerns whether official naming conventions exist.

Answer 1

The R Developer Page contains "more or less finalized ideas and plans for the R statistical system" from R-core. It does not contain any information about naming conventions. A brief look at the core R code will confirm this.

Answer 2

R-core have a coding standards guide, but this does not include variable naming conventions.

Bioconductor also has a coding standards guide, which recommends lowerCamelCase.

There are links to those and several other style-guides here.
