<p>zero or more objects which can be coerced to character</p>

<p>Immediately outputs an warning without the call as part of the error message
that as far as possible is a single line.</p>

Messages should provide users with readable information
about R objects without flooding their console.
'cc()' concatenates vector and data frame values
into a grammatically correct string using commas, an ellipsis and conjunction.
'cn()' allows the user to define a string which varies based on a count.
'co()' combines the two to produce a customizable object aware string.
The package further facilitates this process by providing five 'sprintf'-like
types such as '%n' for the length of an object and '%o' for its name as
well as wrappers for pasting objects and issuing errors, warnings and messages.
