Dear Alexandre, It is possible to do what you want. Take a look, for example, at the dialog box produced by "Statistics -> Contingency tables -> Enter and analyze two-way table" in the Rcmdr package. That dialog box is able to modify itself and to keep variables for an arbitrary number of tkentry() boxes. It does this by constructing names for the variables as text strings, and then using assign() and eval() to set and retrieve values. (Perhaps there's a more elegant way to do this.) The code for the function enterTable(), which constructs this dialog, is in the file statistics-tables-menu.R in the Rcmdr source package.
I hope this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox -------------------------------- > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > [EMAIL PROTECTED] > Sent: Tuesday, March 07, 2006 7:06 AM > To: [email protected] > Subject: [R] Building tkentry dynamicly > > > > > > > Dear R-users, > > I would like to build N "tkentry" compounds in the same > window, with default text for each.
