 		Typically you would call them from R via <link href="rkward://rhelp/update.packages">update.packages</link> and <link href="rkward://rhelp/library">library</link> to achieve this. But RKWard simplifies this for you. You'll be guided through the install procedure for the required package. Please note you need root privileges in certain situations.

-		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.
+		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. In any case you can check the state of R within RKWard. Just look at the little box on the right bottom corner of RKWard. Red means there is still something to calculate or plot. If it's green, R is done calculating.
 
-		But some statistical test are rather memory and stack hungry and can make the entire system unresponsive, if there is a lot of swapping. Please refere to <link href="http://cran.r-project.org/doc/Rnews/Rnews_2001-1.pdf">RNews 2001/1, pg. 10</link> for more information. Therefore, this is neither a bug in RKWard (most likely at least) nor in R but due to the statistical test itself.
+		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 not a bug in RKWard or R, just the calculation taking your system to its limits. An example of very memory hungry tests are the <link href="rkward://rhelp/wilcox.test">Wilcoxon Rank Sum and Signed Rank Tests</link>.

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>, <link href="rkward://rhelp/limit">Memory Limit</link> and <link href="http://finzi.psych.upenn.edu/R/library/base/html/Memory.html">Memory Available for Data Storage</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.
