Maybe this should apply to Ruby forums directly, but I''ll try here. I understand the concept of classes and subclasses thanks to the excellent "Programming Ruby - The Pragmatic Programmer''s Guide". However, I don''t understand what :: signify in terms of inheritance, parent and child in e.g. ActionController::Base -- Posted via http://www.ruby-forum.com/.

Greetings, I am trying to track down a bug with intermittant glitching in our Vorbis streams. I am running Icecast 2.3.2 on Ubuntu 9.04. Several Vorbis clients seem to glitch on some (not all) metadata updates. As we update metadata 3 to 4 times a minute, this is something we are trying to fix, VLC gives the following output on metadata update: main warning: the mixer got a packet in

Hi all, I''m a web designer/-developer. I found Ruby and Ruby on Rails, and as I can understand (for now) this is what I''ve been looking for. I''m really exited about this. Prior to this I''ve used Lasso and PHP. But a few questions (sitting on Mac OS 10.4.6). I tried to install according to this:

DeaR list, let us assume we have stored a couple of functions in 'test.R'. Is it possible to run R CMD BATCH "test.R" or R --file="test.R" interactively and if yes how? A better formulated question sounds like this: how can I source "test.R" interactively OUTSIDE R? Another clarification try: I want to fix the "<my-command> in non-interactive

Greetings, I am collaborating with developing the bigmemory package and have run in to a strange problem when we run R CMD CHECK.

This is so frustrating. Is RoR that easy to learn or is it hype or is it just me? I wonder how many newbies like me are surfing the docs trying to get a clue of the basics. Every tutorial I find is much the same, and seems to skip the fundmental parts. How should you understand the Ruby API http://api.rubyonrails.org/? What is < ActionController::Base?

Dear users, I am looking for a function to choose a folder interactively, just like file.choose() but for a folder.

I've tried to reinstall tcltk with install.packages(), but "package ?tcltk? is not available (for R version 2.15.2)" even though it's already installed on my

Thank you Dan but it isn't my tests that are failing (all of them pass without problem) but one of the examples from the inst/examples directory. I did try, however, to start R with the environmental variables as you suggest but it had no effect on my tests.

Hello all Simple question for the gurus. I'm trying to interactively label curves on a single plot. The labcurve() function from Hmisc seems like the way to do this (?). I just can't seem to get it to work. Toy example: > x <- 1:10 > y1 <- x^2 > y2 <- 2*x > plot(x,y1) > lines(x,y2) > labcurve(labels=c("curve1", "curve2"),
