How do you spell are in a contraction?

* 're: This is used when "are" is followed by a pronoun. For example: "We're going to the park."

* 'r: This is a more informal contraction used in dialects of English, primarily in the southern United States, and is usually followed by a consonant. For example: "You'll be there 'r you won't?"

Keep in mind that "'r" is not generally considered standard English.
