I created a listbox, no problem. Then I bind the Button-1 of the mouse to the listbox to start some things by pressing the mousebutton. The proiblem is that as I click a item of the listbox this error occured:
Error in .Tcl(.Tcl.args(...)) : [tcl] bad listbox index "": must be active, anchor, end, @x,y, or a number.

Editing R graphics
One of the few things that I miss from Splus is
the ability of interactively add text and symbols to graphics
that have been created by functions. I understand that the best
solution in R is to create a graphic file and use external
software for editing the graphic. I know what to use in the
Win environment, but could anyone suggest what tools would
be appropriate under Linux?
Thanks

RODBC and connection parameters
Hi!
I'm using the RODBC packages for connecting R and a mysql database.
To do this, i use the function odbcConnect(dsn,uid,pwd).
Is it possible to read the connection paramters from the odbc.ini file within R?
+Especially I'm interested in uid/pwd parameters because of security reasons.
Thanks
