Dear fellow R users,

valaddin (0.1.0) has been published on CRAN:

Using valaddin, you can transform an existing function into a function with
input validation, without having to rewrite it with stop() or stopifnot()
statements. It therefore provides a convenient and consistent way to make
your functions more robust and more predictable, either interactively at
the console, or in your programs.

To learn more, see:
