comment How to get an adaptive frame which fits auto-wrapped text?
@Silvia I think you can draw the frame after you wrap the text by surrounding your wrapped text, if I understand your question correctly. Or are you asking whether there is a built-in function for this purpose since this effect appears in Mathematica?

I think PatternSequence[{___} -> {_, _}] can be substituted by ({___} -> {_, _})

Moreover, can I show R graphics in Mathematica's notebook (rather than in a new R graphics window)?

Where can I get a full list of the methods (GetSymbol/SetSymbol/EvaluateNoReturn/...)?

I did not notice the warning from statconn's page, saying "...All the statconn tools (statconnDCOM, rcom, RExcel ..) work only with the 32bit version of R..." And everything is fine after I installed the i386 version of R.
