Package R.utils

Utility functions useful when programming and developing R packages.

Warning: The Application Programming Interface (API) of the classes and methods in this package may change. Classes and methods are considered either to be stable, or to be in beta or alpha (pre-beta) stage. See list below for details.

The main reason for publishing this package on CRAN although it lacks a stable API, is that its methods and classes are used internally by other packages on CRAN that the author has published.

Wishlist

Here is a list of features that would be useful, but which I have too little time to add myself. Contributions are appreciated.

Write a TclTkProgressBar class.
Improve/stabilize the GString class.
Mature the SmartComments classes. Also add AComments and PComments for assertion and progress/status comments.

If you consider implement some of the above, make sure it is not already implemented by downloading the latest "devel" version!
