Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value. Therefore I want to add tkentry to allow the user to set tkscale to a certain value. Here is the code library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha",

Hi, I'm trying to produce colored boxplots using lattice::bwplot function. I need to plot each boxplot in the panel with a specific color. Naturally I used a vector of colors and expected to see colored boxplots. Although the boxplots were colored, the color of whiskers and the boxes do not match. Here is an example: d = data.frame(y = rnorm(100), x=1:4) box.color <-

I have doubled buffered animations that I show in class. They used to work but now flash. The default windows() option is buffered = TRUE. Just in case, I tried using windows( buffered = TRUE) but this made no difference. I am not sure when the change occurred. An older R2.11 version in one class room worked. R2.14.1, R2.14.2 and R2.15 don't work on my computer. Some of the animations

I had trouble with some tests for the survival suite last night that I cannot explain. Framework: Ubuntu Linux, R2.11. For testing survival I have a separate directory and Makefile. I pull everything into the local .RData, no packages, library, or namespace. (It's easier to add test modifications to a routine in a chain of calls). A test of survreg + psline would fail because

The xlsReadWrite[Pro] packages allow to natively read/write Excel files (.xls) on the Win 32-bit platform. About a week ago new package versions have been released: * xlsReadWrite 1.5.3 is available at CRAN (for R2.11/2.12) and from www.swissr.org/download (binary builds for R2.9 - R2.12) * xlsReadWritePro 1.6.3 is available from www.swissr.org/download (binary builds for R2.9 - R2.12) * (the

Hello, I wanted to ask if there are any guidelines for Tcl/Tk programming in R ? I know that there are no strict rules concerning programing. But perhabs there are some useful tipps how to organise Tcl/Tk code in your R script. I want to programm a little GUI and I don't want to reprogram the whole GUI in the middle, when I discover that I have forgotten a little detail for example. Thanks

Hello, I am using R 2.11.1 under Windows XP. I would like to know if its possible to use a function with arguments as a command in tcl tk.

Ranjit, Thanks for the follow up, the open source community is incredible. Long story short, I was able to install through the repositories. Then cleaned up some other issues (tcl/tk, java and others) and did a custom install of 2.10. Which brings me to another question, when yum installed R2.11 as an update, did it use the settings from the original 2.10 repository installation or did it

Hello, I am working under R2.11.0 Windows and I would like to ask you if you know a way to save all warning messages obtained by the R function "warning" in a file and keeping the functionalities of the base-function warning. For example if I use external code, I don't want to replace all lines containing "warning(...)" by a selfwritten function. I want to execute it

Hello all, ( I apologize if this posts twice ) Here is my situation. I have 3 buildings linked with 100mbit fiber optics (2 runs that come to the corporate office). I have 3 RH9 boxes, one at each location. Each box at the remote locations have 4 NICs, one for the fiber link, one for LAN, one for the VOIP box and one for the internet connection. The corporate office has 4 NICs also, 1

Hi all, I've been looking for an answer for this issue but Google didn't help. So I resource to the next best thing: the Samba mailing list. Question: Is there a way to automaticaly, after a certain amount of time, unlock a file after, for example, a client crash or network problem? I know how to do it manually of course, but that is, well, cumbersome. I've looked at

Hi, I am wondering if there exists a centos command that runs another command and ensures the second command doesnt take more than x seconds? When x is given on the command line. If the second command is not "done" the first command will just kill it and both exit. Does such a method or command exist? I just need to ensure the second command does just continue to run and run and

Does anyone know how to validate if a file has been selected using a file_field control? I want to ensure a file has been selected before the associated action is selected. Presumably something like validates_presence_of something ? Any pointers most appreciated... John -- Posted via http://www.ruby-forum.com/.

File.open in core Ruby is nifty, in that it automagically closes the file when you''re done using/manipulating it. I''m wondering whether there''s something like that for ActiveRecord? So you can do: AR.find(23).open {|ar| ar.foo = ''bar'' ... } And ar.save would be called when the block closes. -- -Alder
