New section "I think I did something wrong? Where is 'Undo' and 'Redo'?".
Maybe better in RKWard for (new) Users?

This depends. Some test and plots just need some time if you have huge amounts of data or sophisticated calculations. Therefore patience is sometimes needed.
- But some statistical test are rather memory and stack hungry and can make the entire system unresponsive, if there is a lot of swapping. This is neither a bug in RKWard (most likely at least) nor in R but due to the statistical test itself.

Therefore it's important you know the test. Moreover it's very important to save the workspace and other sections you worked on before you do such operations. There is currently no recovery functionality within RKWard in case of a crash! You can find build-in tests from R to address this memory issue but these work on Windows(TM) platforms only (see: <link href="rkward://rhelp/memory.size">Memory Size</link> and <link href="rkward://rhelp/limit">Memory Limit</link>). Sorry to say, this means there is no way for the RKWard developers to build a routine which does a "memory check" before a test is run.

+ Right now RKWard doesn't have any "undo" or "redo" functionality. Therefore it's important that you know what you do before you start. It's recommended to use copies of original data and to give everything a meaningful name.
+ However, RKWard tries to give you as much information as possible about things you have done. For example all test and plots show the specific settings in combination with the creation date. Moreover you can check and copy any code generated for your documentation purposes
+ Depending on available programmer resources, the release of KDE4 and other factors it's likely to be seen in future releases.
