In this articleThis section describes general naming conventions that relate to word choice, guidelines on using abbreviations and acronyms, and recommendations on how to avoid using language-specific names. Word Choice✔️ DO choose easily readable identifier names. For example, a property named ✔️ DO favor readability over brevity. The property name ❌ DO NOT use underscores, hyphens, or any other nonalphanumeric characters. ❌ DO NOT use Hungarian notation. ❌ AVOID using identifiers that conflict with keywords of widely used programming languages. According to Rule 4 of the Common Language Specification (CLS), all compliant languages must provide a mechanism that allows access to named items that use a keyword of that language as an identifier. C#, for example, uses the @ sign as an escape mechanism in this case. However, it is still a good idea to avoid common keywords because it is much more difficult to use a method with the escape sequence than one without it. Using Abbreviations and Acronyms❌ DO NOT use abbreviations or contractions as part of identifier names. For example, use ❌ DO NOT use any acronyms that are not widely accepted, and even if they are, only when necessary. Avoiding Language-Specific Names✔️ DO use semantically interesting names rather than language-specific keywords for type names. For example, ✔️ DO use a generic CLR type name, rather than a language-specific name, in the rare cases when an identifier has no semantic meaning beyond its type. For example, a method converting to
Int64 should be named
✔️ DO use a common name, such as Naming New Versions of Existing APIs✔️ DO use a name similar to the old API when creating new versions of an existing API. This helps to highlight the relationship between the APIs. ✔️ DO prefer adding a suffix rather than a prefix to indicate a new version of an existing API. This will assist discovery when browsing documentation, or using IntelliSense. The old version of the API will be organized close to the new APIs, because most browsers and IntelliSense show identifiers in alphabetical order. ✔️ CONSIDER using a brand new, but meaningful identifier, instead of adding a suffix or a prefix. ✔️ DO use a numeric suffix to indicate a new version of an existing API, particularly if the existing name of the API is the only name that makes sense (i.e., if it is an industry standard) and if adding any meaningful suffix (or changing the name) is not an appropriate option. ❌ DO NOT use the "Ex" (or a similar) suffix for an identifier to distinguish it from an earlier version of the same API. ✔️ DO use the "64" suffix when introducing versions of APIs that operate on a 64-bit integer (a long integer) instead of a 32-bit integer. You only need to take this approach when the existing 32-bit API exists; don't do it for brand new APIs with only a 64-bit version. Portions © 2005, 2009 Microsoft Corporation. All rights reserved.

What are naming conventions in R?Object naming convention
Use only lowercase letters and numbers. Use underscores ( _ ) (so called snake case) to separate words within a name. Use names that are concise and meaningful (this is not easy!). Generally, variable names should be nouns and function names should be verbs.
What naming convention should be used for method names?Methods should be verbs, in mixed case with the first letter lowercase, with the first letter of each internal word capitalized. Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter. Internal words start with capital letters.
Which of the following are examples of variable names that can be used in our select all that apply?Home » Data Science » Data Analysis » Examples of variable names that can be used in R are autos_5 and utility2. Variable names should start with a letter and can also contain numbers and underscores.
