I was looking for a function which would take the difference along a vector? >a<-c(1,12,23,44,15,28,7,8,9,10) if I set the number difference to 3 would return 43 2 5 -37 -7 -19 3 or do I need to write my own function for this. -- View this message in context: http://r.789695.n4.nabble.com/difference-along-a-vector-tp2196594p2196594.html Sent from the R help mailing list archive at

[ -netters, please Cc me or security@ with replies. ] I'm running into trouble integrating dynamic racoon-based IPSec into a network with ipfw and natd. I need to be able to allow VPN access from any address from authenticated clients. I've got the dynamic VPN working, with racoon negotiating SAs and installing SPs, but the problem is that I can't tell whether an incoming packet on

We have a user who purchased a Mac Book Pro with OSX 10.6.2. Everyday he has a problem with one or another Samba Server. One day it's FileShare1 , the next day it's ProductionData Server. I use Windows and Linux and neither has a problem connecting to these servers. He has XP in VMWare Fusion and that works fine. But about every other day he comes and says some server won't allow

I have set up a system to be a member server and installed the samba rpms. I then copied over the samba config file and changed it to reflect the new shares and name change. I ran 'net rpc join - UAdministrator%'secret' and I was able to join the domain. Started up smb and then winbind wbinfo -u and I can see the users in the domain getent passwd shows nothing but the users in

Is there a function that provides the Fisher information matrix for a generalized linear model? I do not see how to access the off-diagonal matrix elements of the value returned by glm. (I'm particularly interested in logistic regression.) If not, what is a good way to use R to compute Hessians or other partial derivatives of log likelihoods? I would appreciate any guidance. David

All, I have been working on a component that is included with samba called SMBSH. The binary allows you to automount your NT shares by accessing your profile . I have been working on this for the last few days and have been unsuccesful at getting it work. Now I am not much of a programmer, but I did my best to try and troubleshoot this. However it just does not want to work in Linux. I

Hello, I'm not quite sure I understand how do you use HDT for dumping over tftp server. The wiki on dumping does not offer much details on how to set this up. >From my understanding is you need to run pxelinux somewhere but being that HDT is a bootable cd ISO, I don't see how I can get HDT up from a TFTP server without the need to install something on that TFTP server. Is there a more

Hi Yeah I ended up figuring it out My usage for the tool will be to gather hardware specs of new servers that we receive and servers we have in storage I will then see if I can script something to phrase the dumps to update our inventory tool. Our main issue is that gathering information manually by opening the server and having to locate each parts is time consuming and being humans we are

Hi, I must be missing something or have something misconfigured, but I get no stack-trace when there is an error in the code behind a view. If the view doesn''t compile, then I see an error & stacktrace, but all other errors I get a "lost network connection" from the browser, and nothing at all in the server output or development.log. It''s been that way with

Hello, I am new to R. I often collect data at multiple sites and need to create separate graphs (such as scatterplots or histograms) of specific variables for each site. I have tried to do this by splitting the data frame and then using lapply, but it seems that the graphing commands cannot be called as functions. Here is a sample of my data, called "seeddist2": site

Dear R users: I have the following matrix. 0 1 1 0 1 0 2 1 0 3 0 0 I would like to spread the matrix such that whenever the row sum is greater than 1 the row is repeated the number of times given by the row sum. Furthermore I would like to split the following cases: 0 1 1 such that it map to the following matrix 0 1 0 0 0 1 such that each row adds up to 1. I have no problems with cases

Has anyone else encountered this problem? What I mean is, rspec_autotest runs all specs, then waits. When you change a spec, it reruns that spec. However, if that spec now passes, it should run the whole suite again, so you can see the next one to work on. It no longer does this. This renders it somewhat useless. Does anyone have autotest working with rspec 0.7.5, or does anyone have any

How would I set up a model stub so that <%= error_messages_for ''some_model'' %> doesn''t complain? I started going down this road: @some_model.stub! (:errors).and_return(ActiveRecord::Errors.new) but it seems like a long, hopefully uneccessary road. Cheers, Michael

Hi All, Is there an option in asterisk to manipulate the audio in a call? I would like to, for example change the voice of one caller but without manipulating the audio that comes from another caller. I have read about something called JACK but i don't know if i can use it for this (or how to use it). I am playing with audiohooks now, but I don't think I can change only my voice - whole

Hi, I used split.screen command to creaye 5 screens, 4 screens contain a plot each, the fifth screen is designated to a legend. I am having difficulties setting the dimensions of the screens in a way that would allow me to have the screen dedicated to the legend smaller. I end up with a very awkward aspect at the end: 4 small plots with a big space for the legend. The gend needs to be at
