...ions. RGtk2 also adds a new library to its interface: GIO (2.22), a low-level library supporting asynchronous streaming I/O, mounting of volumes, networking, etc. Might be useful. There is also a new mode of error handling available, that is disabled by default. By setting the option "RGtk2::newErrorHandling" to TRUE, errors in the libraries will result in errors in R (instead of warnings), and the error object is no longer returned, which often simplifies return values by no longer requiring a list to hold both the error and the original return value. This is probably a more sensible strategy....
