similar to: as.numeric with tclvalue redux

Dear R People: I have an interactive menu via an Rcmdr extension package which asks for lower and upper limit to evaluate. Typically, I use: assign("a",as.numeric(tclvalue(lowlim)),envir=.GlobalEnv) and that's fine. However, if I try to use pi or Inf or -Inf, I get either coerced NAs or NaN. Does anyone have any suggestions, please? Thanks, Erin PS Happy Easter if you

Hi everyone, I have a problem to assign a value with tcl/tk ths is the code ( it should be simple to understand) : library(tcltk) valA<-tclVar("0") valB<-tclVar("0") valC<-tclVar("0") id<-"A" out<-"1" out2<-"2" print(paste("tclvalue(val",id,")",sep="")) # ok

Hi thank you for talking the time to help me with this. I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e 2 a show a green dot 4 b show a

Dear R users, I have some troubles with dealing with tclObj objects. I try to explain it with a toy example: Say I define the following tcl procedure which just prints out each list element library(tcltk) .Tcl('proc test {myList} { foreach i $myList { puts stdout $i } }') and I call it with: > tcl('test',letters[1:5]) # Works as expected Now say I define

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see any obvious way to do it ...

Hi everybody, I am trying to write a simple progress display based on a tcltk toplevel. My first approach was to use the progressBar widget from the BWidget library but since this is not available on every system (missing on at least almost all windows systems, I guess...) I wanted to have a backup there. So my second strategy was to use a simple toplevel with a label and update the tclvariable

Hello, On Mac OS X, certain Aqua/Quartz UI functionality requires an application to be launched from within an app bundle, or (alternatively) requires a Carbon application with a resource fork. Playing with the wxWidgets distribution, I discovered that it is quite easy and transparent to make such a Carbon app from (I guess) any command line application. When applied to the R executable called

Hi, all, (sessionInfo at the end) I've been struggling with the tcltk package and can't seem to get the ttkcombobox to work. Here's an example: library(tcltk) p <- tktoplevel() l <- tclVar() ## I don't know if I'm even calling it correctly cb <- ttkcombobox(p, values = letters[1:4], textvariable = l) tkpack(cb) 1. How do I know when the value of the combobox has
