similar to: r noobie, reading my text file into r

NB: Not reply needed (Ben was extremely helpful!) I've just started using R last week and am still scratching my head. I have a data set and want to run a separate regression across each level of a factor (treating each one separately). The data right now is arranged such that the value of the factor along which I want to "split" my data is one column among many. Best way to do

1. I have a list of lm (linear model) objects. Is it possible to select, through subscripts, a particular element (say, the intercept) from all the models? I've tried something like this: List[[1:length(list)]][1] All members of the list are similar. My goal is to have a list of the intercepts and lists of other estimated parameters. Is it better to convert to a matrix? How to do this? 2.

I have the following helper method in application_helper.rb: def format_date(date) day = to_s(date.day) month = to_s(date.month) time = to_s(date.time) date = day + "/" + month + " - " + time return date end I am trying to call this method in a view like this: <%= format_date(bounty.created_on) %> create_on is a timestamp in mysql. I am

I have a 43MB dataframe ( 5 variables) and I'm trying to summarize subsets of the data. I've RTFM ( not very clear) and looked at a variety of samples but cant seem to figure out how to make these functions work. A sample of what I want to do would be this: ids<-seq(1,50) years<-c(rep(5,10),rep(6,10),rep(7,10),rep(8,20))

Dear R list, I've been attempting to interpret the results from a three-way ANOVA. I think I understand contrasts and the R defaults for these (treatment contrasts). My question is: what is the intercept in this test? As far as I can tell, its NOT the expected value of a point that belongs to the first level of all three explanatory factors (because there is only one point that satisfies these

Just a note: This is similar to the problems I am (still) having. I too am using Redhat9 (Icecast2 and Ices2). I've used Winamp2 (Zinf tells me the data is corrupted), but instead of the high-pitched noise you describe - I get dead silence. Of course, everything leads me to believe that the connection is healthy and the stream is working. There's a

New to Ruby, getting "Application error (Rails)" when trying to access the page. Noticed in apache logs permissions denied problem to the fastcgi.crash.log, fixed that with chmod 777, now it just shows the pid that failed....what do I do now?

I know that windows exe files can be run using Wine, but I have a windows program I would like to run under PCLINOS and the update/patch is in the form of a .com file. Can a file of this type be used for the update/patch in Wine ?

Hello again, I have been working on the Rice Encoder/Decoder now since my first post. However, I can't identify what's wrong with it. I was hoping there might be someone out there interested in answering my questions outside of this forum. I am not very good at programming at all, but I really want to see this project come together with my own work. (i.e. I don't want someone just

Hi: Since icecast2 is still heading to an initial release, there's no official guide for this stuff, but there is a bit of stuff out there. First, lets clarify what you want to do. When you say "CD content", I assume you mean audio CD's. To provide a stream requires two parts - a source or streamer, and a server. The source is equivalent to a radio studio, the server is

Thanks, all, for the pointers. I think I have everything configured properly, but, something is obviously still wrong. I'm using Kerry's guide with these xml files: - Sample icecast.xml - Configuration for Streaming Live Audio I started icecast & ices as directed. I then started xmms and configured the output plugin to be the OSS driver. I'm playing a music cd. This is all on my

Should I actually have a "radiofree.ogg" file being written on my Linux box? If so, I don't see it. I'll try a different player as well. --- Kerry Cox <kerry.cox@ksl.com> wrote: > Winamp3 is broken according to some posts here. Try > Winamp 2.91 or the > latest XMMS.

I''m just at the "reading various rails tutorials" stage. One thing that has puzzled me a couple of times so far is the fact that the creation of the database is not part of the "migration". The steps as I''ve seen them are always: 1) $ rails myapplication 2) $ mysqladmin yadda yadda to create a table 3) $ script/generate migration myWickedTable 4) put rows

That is set up via the config file and is used for accessing the stream. I do not believe there is ever any static radiofree.ogg file created. It is used for streaming purposes only. Though I could be wrong. I just have never bothered to look. Someone correct me if I am. KJ On Fri, 2003-09-12 at 16:14, Jeff Ousley wrote: > Should I actually have a "radiofree.ogg" file being >

Hi, I''m teaching myself to use wxRuby and DialogBlocks to create a front end for a Ruby program I wrote. And I''m hopelessly stuck! In DialogBlocks (or indeed wxFormBuilder, which gives me the same problem) I can create a widget, give that widget a new id and class name (in the example I created below, text_box1 and CaseChangeTextCtrl1, respectively), and then add a module which

Winamp3 is broken according to some posts here. Try Winamp 2.91 or the latest XMMS. Of course, XMMS requires the xmms-mp3 libraries. Try that and see if it helps.

Hi, I'm at my wits end and need help regarding my UPS. I am a newbie to Linux (10 months) and need help with trying to configure my UPS to my Linux SME server. I have little or no experience with Bash and am finding it overwhelming when it comes to trying to configure my UPS. I have installed my UPS to my Linux SME server and have installed my driver for it. At best I think its running but

Hello! I'm extremely new at this so don't hurt me. I want to stream CD content from my RedHat 9 box using icecast? What is the best way to do this? I'm getting confused with all the different pieces and configurations. Is there a simple guide that discusses what I want to do? thanks! __________________________________ Do you Yahoo!? Yahoo!

In my webapp a todolist has many todo items. I am trying to display lists that are completed. By incomplete I mean that all the items in that list are done (booolean = true). I hope to have a list of active lists and complete lists on one page. I''m no ruby expert by any means so I think I have to ''pipe'' some results into another query?? Can you help please? -- Posted

Hi, A noobie question: I'm simply trying to run a conditional statement that evaluates if a substring is found within a larger string. I find that if it IS found, my function returns TRUE (great!), but if not, the condition does not evaluate to FALSE. ex): if( grep("hi", "hop", fixed = TRUE) ) print('yes, your substring is in your string') else
