Greetings Friends: I am trying to find a widget or some other method to let me interrogate a 2-D image using the mouse. I have a data.frame that I can visualize using image() in R. I would like to point to a pixel and have its coordinates displayed. I've read Peter Dalgaard's primer on R-Tcl/Tk, R-News, 1(3):27-31, and his update R-News2(3):25-27, but am still struggling. Can anyone

Mike, excellent suggestion! I will definitely experiment with that nsswitch change. Rowland also mentioned adding RFC2307 to the AD settings for the user(s). If, as you say, my MTA will find the home directory with the nss windbind setting, that would be fantastic! I would definitely removed the AD users from /etc/passwd. I don't know if nsswitch.conf settings are now mentioned in the

More experimentation ... I stopped Samaba, ldbedit'ed the /var/lib/samba/private/idmap.ldb and changed the line xidNumber: 3000026 to xidNumber: 10001 killed the cache and restarted Samba. As I hoped, the wbinfo now showed $ wbinfo -i mark HPRS\mark:*:10001:10000:Mark Foley:/home/HPRS/mark:/bin/bash which was NOT the case in my message below after killing the cache. In that previous

Hi, The following code, from the examples in ?TkWidgets , immediately crashes R 4.0.1 for Windows: --------------------- snip -------------------- library("tcltk") tt <- tktoplevel() label.widget <- tklabel(tt, text = "Hello, World!") button.widget <- tkbutton(tt, text = "Push", command = function()cat("OW!\n")) tkpack(label.widget,

Hi, I have a table with data, as below: dput(table): structure(list(Adrian.Cole = c(0L, 0L, 0L, 0L, 0L, 0L), Alison.Wong = c(0L, 0L, 0L, 0L, 0L, 0L), Andrei.Savu = c(0L, 0L, 0L, 0L, 0L, 0L), Bruno.Dumon = c(0L, 0L, 0L, 0L, 0L, 0L), Edward.J..Yoon = c(0L, 0L, 0L, 0L, 0L, 0L), Eugene.Koontz = c(0L, 0L, 0L, 0L, 0L, 0L), Jakob.Homan = c(0L, 0L, 0L, 0L, 0L, 0L), Kelvin.Kakugawa = c(0L, 0L,

John, The Windows installation instructions document has the following. So, one obvious question is whether you did select it. (I haven't installed on WIndows for ages, so I don't know whether this was changed recently or even whether the selection is on or off by default). -pd Using package tcltk =================== The package tcltk supports building graphical interfaces with Tcl/Tk.

Hi All, In my continuing efforts to get WeatherScope running flawlessly under Wine, I've noticed issues with WeatherScope's built in color chooser. When you run the program, by default a map of Oklahoma appears. If you right click on the entry in the legend (on the left side) and select properties, you have the option of choosing the color. If you click on the small color button, the

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 ...

Sir, Kindlly Guide me how to get the R CELFILES.

I''m working on some schema for a new project that we''ll be doing in rails (our first rails project!). A recurring structure we are seeing is the desire to define an ordering any way we wish, so ''acts_as_list'' comes to the rescue. But, the ''position'' column seems to need to belong in the join table to make sense. For example, we have

Hi, looking to see if I''m on the right track here... we''re selling widgets to customers, but there are a number of different type of widgets and each different type of widget has a number of parameters that the customer can specify, in effect each customer orders widget''s customised in ways particular to that specific order. We use STI to store each different widget

Hi, I posted this message on the StatET-user board last week, but it looks like a ghost-town... I have a bad feeling that there is some code in the plug-in which doesn't work well with my environment, but if I am lucky, maybe other users have worked around this problem somehow - I am hoping that my setup is the issue. Note: very similar StatET setups on 32-bit XP Pro and Vista run

Hi, I've been playing with the tcltk package. It's very nice to have access to buttons, menus etc. now. Thank you! Alas, I also have questions: In Tcl everything is a string [*]. This is not the case in R, of course. So why are return values of tk commands still strings? (Is there any other reason than speed or "package is work in progress"?) Example: > tt <-

Hi list, how are ya? So, my current project is just begging for the ability to have parameterized associations in my ActiveRecord classes. Basically I need something that is a cross between named scopes and standard associations (has_many specifically). I''m wondering if such a thing exists or, if not, if anyone else has an elegant, equivalent solution? Example: class Sprocket <

I think I - almost - got the knack for GUI programming using the tcltk library. Maybe I will update the RWiki with this: # ################################################# # library(tcltk) # # Create some matrix - nothing about tcltk here # matrix <- cbind(rnorm(100), rpois(100, lambda=10), runif(100), rt(100, df=2), rt(100, df=4)) colnames(matrix) <- c("Normal",

Hi there, I''m fairly new to RSpec, and DataMapper and I''m trying to write a controller spec for an index action that will include DM query chaining. Here is a very simplified version of the Controller#index I''m working on def index @widgets = Widget.all(:order => [ :name.asc ]) if params[:alpha] @widgets = @widgets.by_alpha(params[:alpha]) elsif
