Taking the Grunfeld data, which is built-in in R, for example, (1)How can I construct a dataset (or dataframe) that consists of the data of all firms in 1951? (2)How can I calculate the average capital in each form over the period 1951-1954? What I can imagine is to categorize the data by firm, and then select the data between 1951 and 1954 for each firm, but how can I do it? Thanks, Miao

Hello All, I''ve just sent off the source code for wxRuby Socket''s demo to Sean and Alex to do some final testing on Linux and MacOS X, to ensure compatability of my design with those two operating systems. Once confirmed, the demo will be posted to the SVN. What is basically entailed within these two demos, is the implementation of a Server with a GUI Front End, and the

Hi I''d like to put out a 1.9.3 release perhaps later this week/weekend. If you have a chance to test the build and samples esp with latest rubygems, please do. There are still some bugs on the list, and samples to do, but this should address all the build/install probs that have come up. And it would be good to get some testing and feedback on some of the new classes. A note on the

Hi, I''m trying to compile wxruby-1.9.2. This is my first time using rake.

Hi R-Help! My question: I have lifetime/failure data of machines with different stress levels and i think an weibull/extreme value distribution would fit this data. So I did: model1 <- survreg(Surv(lfailure)~stress,data=steel,dist="extreme") (where lfailure=log(failure)) Now I would like to do a likelihood ratio test to test the hypothesis H0: location parameters of the

Hello All, There seems to have been a lot of interest in getting wxScintilla incorperated, and I think most of us who want it, want it so we can create an editor, so to avoid multiple projects comming out with the same goal (Not really that bad of a problem....), I''m going to kick start this, and ask that anyone interested in developing a Editor with wxRuby and wxScintilla, to send

I would like to take a rails page and convert it to a pdf. I don''t want to have to generate the code myself for making the pdf, so it should obey css. What is the best tool for doing this? Does the tool use the standard css, or can I provide it alternative print-css? Thanks in advance, Jonathan Steel -- Posted via http://www.ruby-forum.com/. -- You received this message because you

Hi all, I just noticed that in ActiveRecord::ConnectionAdapters::Column.type_cast[1] (and type_cast_code[2]) the type casting for float columns simply does value.to_f, whereas all the others have a rescue or call out to a method, the default implementations of which have rescues or enough logic in that I don''t think they''d fail. Imagine the following: create_table :vehicle do

Is there a better way to express operations between matrices and column vectors than transposing the matrix twice? This is the kind of thing I'm talking about: m = matrix(1:20, 3, 4) v = colSums(m) t(t(m) / v) ## <-- kinda ugly, ain't it? I thought of converting the column vector to a matrix: m / matrix(v, nrow = nrow(m), ncol = length(v), byrow = TRUE) But that seems even
