Hello everyone, this is my first post here and I hope I signed up correctly and someone will take me by the hand and help me out. I am new to R and cannot figure out what to do here...
... I want to have an User Interface that requests input. I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog ( http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/modalDialog.html like this ) but I cannot figure out how to do this with multiple values to be read. I want to run a rather simple simulation and the user has to be able to set multiple parameters (say, number of trials and stimuli). The onOK-function should then "collect" these parameters and save them to variables (I guess). Here is a snippet of my code. Could someone tell me what to do? Am I heading in the right direction or is my approach hopeless? :p ------------------------------------------------------------- OnOK = function(){ # I reckon this is where the important stuff should happen... tkdestroy(tt) } require(tcltk) tclRequire("BWidget") tt = tktoplevel() trials = tclVar("100") # I want to suggest default values but they should be editable. entry.trials = tkentry(tt, width = "3", textvariable = trials) tkgrid(tklabel(tt,text="Number of trials:")) tkgrid(entry.trials) Stimuli = tclVar("10") # I want to suggest default values but they should be editable. entry.Stimuli = tkentry(tt, width = "3", textvariable = Stimuli) tkgrid(tklabel(tt, text = "Number of stimuli:")) tkgrid(entry.Stimuli) OK.but = tkbutton(tt,text=" Go! ",command=OnOK) tkgrid(OK.but) tkfocus(tt) ------------------------------------------------------------- Of course, I also tried to find a solution via google but couldn't really find anything. http://tolstoy.newcastle.edu.au/R/e4/help/08/07/17422.html The only thing I found was this post which never got answered . I hope someone can help. Thank you very much for reading this and any help is greatly appreciated!
