newbie- launch X11 application from a R tcltk GUI

my last question (I swear)
I still have a problem with open,

I create a connection
conn<-file("/Applications/visone-1.0", "r")

then I try to open it

open(conn)

but nothing happens... :(

thank you very much

depends on $PATH. if foo is in $PATH then open
will work. open-x11 looks in /usr/X11R6/bin
even if it's not  in $PATH

Actually, for an X11 app, wouldn't it be "open-x11 foo" instead?

Dear List,
I'm developing a tcltk GUI with R tcltk package.
One of the function I want to put into my GUI is the ability to
launch an X11 application and I am wondering the command I need to
accomplish my task.

thank you,
Simone





It was simple, but you know, it's always simple when you've done
it.
