concatenate: concatenate: Comma Concatenation
In concatenate: Human-Friendly Text from Unknown Strings

Each function in concatenate returns a comma-separated string. (A length-one character vector.) They can be used to construct human-friendly messages whose elements aren't known in advance, like calls to message, warning or stop, from clean code.

The workhorse function is cc. cn combines it with grammatical number awareness, as in ngettext, and sprintf-like substitution.
