[Rd] RAqua

[John Fox]

Dear Jan and Peter,

Given Peter's explanation, setting options(Rcmdr=list(tkwait=TRUE)) before 
loading the Rcmdr package might allow the Commander to work (although it 
will disable the R command prompt while the Commander window is open). Not 
a good solution, of course.

Regards,
  John
