Hi, I am having trouble debugging this one. The code is attached below, but it seems to be a problem at the C-tk interface. If I run this 1 time there are no problems if I run it more than once I start to get warnings that increase in multiples of 11 everytime I run it. Here is a sample session > source("clrramp2.r") Loading required package: tcltk Loading Tcl/Tk interface ... done

Hello, i'm trying to translate following tcltk source code, which I found in newsgroup comp.lang.tcl, written by Tom Wilkason, into R Code. proc scrolled_Canvas {base} { frame $base.fm -borderwidth 2 -relief sunken canvas $base.fm.cv -yscrollcommand "$base.fm.cv_vertscrollbar set" scrollbar $base.fm.cv_vertscrollbar -orient vertical \ -command "$base.fm.cv

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Hi, I think that R-tcltk doesn't have the capacity to display an image stored in memory on a tkcanvas object, am I right? I have digged around everything I can find from Peter Dalgaard and tcltk references and drew my conclusion. Can you, Peter, or some other gurus on the list, give us a pointer or two on how to proceed to solve this problem? I am afraid that it may involve writing C

I generate a lot of URL''s in my Facebook related code that point to our main site, not our FB app. My understanding was that the way to do this was to use ":canvas => false" as a parameter to url_for and link_to and so on. However, that doesn''t seem to generate the proper URL''s. The URL''s still point to apps.facebook.com (because they

Hi all, Just looking for a quick sanity check. I was thinking of writing a plugin for rails to give rails developers a good way of using the new firefox 1.5/safari canvas tags. I was thinking of grabbing an existing ruby graphics library and modifying it so that it renders via the canvas tag.. So you could have link_to_remote pointing to controller actions that instead of returning

Hi guys, I am new to this list and thought i''d say hello. I am using facebooker on a new project and so far I am really pleased with it. I saw that some users are having woes with the url_rewriter breaking urls for paths outside of the facebook canvas (i.e. your site supports both facebook and non-facebook users). I don''t have a prefect answer for this but I wrote a

I found a reference to using attachment_fu and followed the lead of it but having an issue with the redirect_to that renders the fb:render tag - In my form I''m setting the canvas to false, file is being uploaded / save fine but when I attempt to redirect: redirect_to :action => :new, :canvas => true Unfortunatly it looks like my callback URL is getting printed twice, e.g.

How can I use the drawing canvas and its off-screen image buffer, say FXImage, to dynamically resize or have its width and height attributes changed in reply to user interaction with the main window (FXMainWindow)? It seems that whem I put initial values to W and H of the canvas or FXImage, they remain with its initial values no matter what I do whem resizing the main window. -- Ranieri Barros

The URLs for CSS/JS files are being rewritten to the address specified in the tunnel even when outside of the facebook canvas. Is anyone else having this problem?

I''m working on an app, and am new to both ruby and facebooker. Here is my current area of confusion: What should happen on a user''s initial visit to my app? When I hit apps.facebook.com/<my app> for the first time with no cookies or sessions or anything, I''m asked if I want to log into the app, etc., and am then redirected to my callback url outside of facebook.

So I have an existing app & facebook app in same rails application, for now I have decided to go the route of creating a controller for facebook stuff (called FaceController). (setup is canvas, fbml) So I have: facebook config http://myurl:myport/face/ My controllers name is face, so I dont even need a manual route, for the landing page it works like a charm. but, when I try to make

Hi All, I''m trying to use a form to upload a photo that I will save using attachment_fu. I''m very new to Facebookr so I apologize if this is covered somewhere, but I''m kind of stumped. Here''s what I''m doing now: <% facebook_form_for(:my_object, :url => { :action => ''upload_photo'', :id => params[:id] }, :html => {

Hey folks, I''m part way through a project using, I think rev 73 of Facebooker, and was getting along pretty well. I''ve since tried the latest rev (86) and have run into a few problems. First one was with the helpers in that for some reason now none of them are available so I''ve had to use helper :application, etc in my controller. Second one, which

I''m working on the ability to share a single session between Facebook and Non-Facebook requests. Right now, to setup a shared session, you create a link like: <%= link_to "Non-Facebook view",leaders_url(facebook_session_parameters.merge(:canvas=>false))%> The facebook_session_parameters includes all of the necessary info. Is this okay, or would it be better as

Hi I am having a bit of difficulty with changing the canvas size on a trellis/lattice plot. I am plotting two "cubes" of 3-dimensional random numbers, as follows: library(gsl) library(lattice) q <- qrng_alloc(type="sobol", 3) npoints <- 200 rs <- qrng_get(q,npoints) # Plot the normal variates in a 3-dim cube p1 <- cloud(rnorm(npoints) ~ rnorm(npoints) +

Hi, I was wondering if someone in the mailing list has any insight into this segfault error that I consistently find when running a script containing heatmap() in R 2.8.1 and 2.8.0 on a Linux 64-bit machine. Some points: 1. This occurs when running heatmap(). 2. Interestingly, if I source() the script or copy and paste the script in its entirety, this error occurs. However, if I run the

So if I am using fbml,canvas & facebooker, can I do ajax calls? if so how? From reading it seems they support some sort of mock ajax, but I don''t really understand, can somone explain to me? If I cant do ajax, can I still do javascript? Can I use 3rd party libs like prototype & scriptaculous? thanks Joel
