Hi, I want to assign the ar1 , ma 1 and the intercept estimated by the following<http://r.789695.n4.nabble.com/assign-estimated-values-td4658138.html#>code to three variables a, b and c respectively. Can anyone help me with this please? code: a0 = 0.05; a1 = 0.1; b1 = 0.85 nu = rnorm(2500) epsi = rep(0, 2500) h = rep(0, 2500) for (i in 2: 2500) { h[i] = a0 + a1 * epsi[i-1]^2 + b1 * h[i-1] ; epsi[i] = nu[i] * sqrt(h[i])} epsi = epsi[1501:2500] epsi=epsi*epsi arma(epsi,order=c(1,1)) -- *Malaka Thilakaratne Department of Mathematics and Statistics Missouri University of Science and Techno...

I am creating postscript-graphics in R. When I import them into a LATEX document it is impossible to get the caption close to the figure. I run the same program in Splus, and no problem of getting the caption just below the figure. Another thing, the ps file that S created is only 10% of the size of the file that R created. What is wrong? Are there some parameters to be set? Helgi

Dear colleagues, I have an image which I can display in the greyscale using image. On this image, for some pixels, which I know, I want to display their activity based on a third measure. One way to do that would be to color these differently, and use an opacity measure to display the third measure. An example of what I am trying to do is at:

I've created a bunch of postscript trees (post.rpart), which I subsequently edit in Adobe Acrobat 4.05 (I need additional labelling that isn't easy to add with R). After editing the labels and annotations using Acrobat, I then export the file to Adobe's .eps format so I can insert the picture into a Microsoft Word 2000 document. The .pdf file distilled from the .ps file is

Hello all, I am having some problems with the group policies in a small (~10 pc's) AD. I have set up Samba and i used a NAS for saving home folders and policies. I then had to replace the NAS and i used a new ip for the new NAS. For the last step i changed the ip of the redirected folders in the policy in order to point all pc's to the new NAS. It seems the policies are not applied
