I get at these demo when I do

the second message.> On 12 Mar 2015, at 09:04, peter dalgaard <[email protected]> wrote: > >> >> On 11 Mar 2015, at 23:41 , Erich Neuwirth <[email protected] >> <mailto:[email protected]>> wrote: >> >> OSX 10.10.2 >> R 3.1.3 >> XQuartz installed. >> >> I am trying to run one of the tcltk demos > > Which demos?
