TclTk object in R -

-

I am new to R (and programming in general), so apologies if it has been answered a bit more then

find me No response was received, but any help or direction would be very good!

I am trying to create a clickable interface on R, where I can click the users to find a file 

  requirement (tcltk) Getfile & lt; - Function () {Name & Lieutenant  
; -tclvalue (tkgetOpenFile (file type = "{{CSV files} {.csv}}")) if (name == "") return; Datafile & lt; - read.csv (name, header = t)} tt & lt; -tktoplevel () button.widget & lt; -tkbutton (tt, text = "select csv file for analysis", command = getfile) tkpack (button .widget) #CV variable of the CSV file is placed in 'datafile'

However, when I try to execute it, and after clicking the button, click on the CSV file of interest, nothing happened. 

  Error: object 'datafile' not found

Once again, any help is greatly appreciated thanks!

The top-level object contains an environment in which you can store things, keep them in the local GUI done Give your callback as an argument: 

  #backback that reads a file and stores DF at upper level dev: getfile & lt; - Function (tt) {name & lt; - tclvalue (TkgetOpenFile (filetypes = "{{CSV files} {.csv}}")) if (name == "") returns; Tt $ env $ datafile & lt; - read.csv (name, header = T)} #backback that does something for data frames (must first check existence!) Dosomething & lt; - function (tt) {print (summary (tt) $ env $ datafile))} # create a dialog with a load button and do some button: tt & lt; --tktoplevel () button.choose & lt; - tkbutton (tt, text = "select csv file", command Tkpack (button.choose) button.dosomething <- tkbutton (tt, text = "do something", command = function () {dosomething (tt) } Tkpack (Button. It should be quite strong, although I'm not sure if there is something already in the environment that you should be careful in the stomach, then create and use an environment in that environment. For storage.  
 If you want to exit the dialog and do things for the user Prompt for micro want to save, name and assign  or  to store them in . GlobelEnv  to exit.

winforms - C# Form - Property Change -

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
