similar to: More than one has_many :through association between the same 2 models

Dear R-users, I have very recently started learning about object-oriented programming in R. I am far from being an expert in programming, although I do have an elementary C++ background. Please take a look at these lines of code. > some.data = data.frame(V1 = 1:5, V2 = 6:10) ; > p.plot = ggplot(data=some.data,aes(x=V1, y=V2)) ; > class(p.plot) ; > [1] "ggplot" My

Hi all, I am trying to add an article editing interface to my future webstore, and I am wondering what to use for text formatting. I would like to avoid using HTML, and calibre-bbcode just won''t work (see my last post). Is there some kind of library for live text formatting right in the browser? I would just need bold, italics, size and ul lists... Do you know of a good solution?

Hi all, I''ve been spending quite a lot of time trying to install a decent RoR server on my dedicated server (Ubuntu 6.06 LTS), and now, everything works.

Dear all, I am having problem to create a package when this package is supposed to have some newly created s4 class. Here is my workout: > #rm(list = ls()) > setClass("aClass", sealed=T, representation(slot1 = "vector", slot2 = "character")) [1] "aClass" > fn1 <- function(x, y, z) { + x <- x[1] + y <- y[1] + z <- as.character(z[1]) +

The Time::next_week method is supposed to give the time of the start of the next week. But look at this, it cocks up : >> t=Time.parse "Monday October 16th 2006" => Mon Oct 16 00:00:00 BST 2006 >> t.next_week => Mon Oct 23 00:00:00 BST 2006 >> t.next_week.next_week => Tue Oct 24 00:00:00 BST 2006 >> t.next_week.next_week.next_week => Mon Oct 30

Hi, I am currently experimenting on rake freeze_gems and there is something I do not understand. When I freeze_gems my app, it puts Rails in the /vendor/ directory, which works. But what about all other gems I have installed (for example Unicode, sqlite support, mysql support and so on)? The aim of freezing is to be independant of the versions of the ISP, but it seems that the server still

Hi all! I am trying tu set up RedCloth for user-submitted comments. And here is my problem. The :filter_html option just breaks images :-( For example, if I try in irb: string= "Some textile !agif.gif! and textile again" RedCloth.new(string, [:filter_html, :filter_styles]).to_html(:textile) I get: NoMethodError: You have a nil object when you didn''t expect it!
