Dear forum, I would like to forecast e.g. with the arima-model. To figure out which model works best I am going to predict with this models. my first code: for(ar.ord in 1:3){ for(ma.ord in 1:3){ print(predict(arima(para_qtr[1:(n-8),1],order=c(ar.ord,1,ma.ord)), n.ahead=8)$pred) } } this one works. but I want to "save" my results in a matrix or a data.frame. my second code:

Hi, I am trying to use rsync to migrate homefolders from one server to another. For this I use: > rsync --rsh="ssh -l root" -vaz beaucent.ling.umu.se:/export/home/ .

About six months ago there was a reference to a site (in french) that did a spectacular job of demonstrating R's graphical capabilities. My bookmarks were recently wiped and I cannot find this site despite my best googling. Anyone have the address which I have done a miserable job describing? Thanks. Michaell

I''m trying the auto-complete on Opera 8.5. I know it is not officially supported but it mostly works. Just one little problem: Opera seems to have some issue with .scrollTop on a input control. I expect it to report 0 but it report its current coordinate. So the update window goes to a wrong location. This is a block of code in Position.page page: function(forElement) { ...

Please could someone point me in the right direction as I appear to be having a total mental block with fairly basic PCA problem! I have a large dataframe where rows represent independent observations and columns are variables.

Hello, I apologize for this question that may has been asked a lot of times but I could not go through it. I create a multivariate time series containing NA values. I want to compute a linear regression and obtain a time serie for both residuals and fitted values. I have tried the trick ts.intersect, without success. Could you help me out of this? #### Example: y<-ts(1:10+rnorm(10))

Note that this does not fix gettext for app, that will be done separately in another patch as F10/F11 require different setups for that. In the meantime gettext works if manually changed in environment.rb to gettext_rails instead of gettext/rails Signed-off-by: Jason Guiditta <jason.guiditt at gmail.com> --- src/app/controllers/application.rb | 200 --------

Note that one of the 8 patches (#6) will be sent separately in reply to this email, as some of the replaced lines are too long, so git won't let me send the email. However, there is nothing wrong with that patch, and it should be applied in the sequence listed below. Note also that I assume this will be tested on a clean f11 install, rather than an upgrade of an existing ovirt server
