...txt, header = TRUE)))) IBM <- ts(read.table(IBM.txt, header = TRUE)))) but is there another way to achieve the same actions as above with a more versatile way? (for example loops?) Or would you suggest inputing these data with another way or as other objects? Thank you very much in advance,... Tsardounis Costas

...n demands more than 50 lines at the beginning of the script that "initiate" the lists (e.g. example.list.1 <- list() example.list.2 <- list() ... example.list.50 <- list() << 2 >>. Is there a way to avoid that? Thank you very very much in advance, Constantine Tsardounis

...it is possible to regress a model with the Least Squares method, assuming that the residuals follow an AR(q) process. For example the resulting regression is something like y = 1.2154 + 0.2215 x + 0.251 AR(1) How is it possible to do the same in R? Thank you very much in advance, Constantine Tsardounis http://www.costis.name

....csv("1.2.2-askhseis.econometrix.csv")[ ,2]) garch(summary(lm(y ~ x))$resid^2, c(0,1)) What I am doing wrong? Because I want to check for ARCH(q) effect and then estimate the final equations (Y on X, with the equation of the error term) Thank very much in advance for your assistance, Tsardounis Constantine Student in Economics at University of Thessaly, Greece Eviews results: Dependent Variable: Y Method: ML - ARCH Date: 12/26/05 Time: 00:05 Sample(adjusted): 1 83 Included observations: 83 after adjusting endpoints Convergence achieved after 16 iterations...

...an find the mean of the series on all of these files/loaded objects with a loop that uses the command mean(wmd.txt.R) instead of mean("wmd.txt.R") that does not work... Could you help me, please or propose another way to achieve the same result? Thank you very much for your assistance, Tsardounis Constantine

...s". I can understand that the whole problem is an encoding issue, but what should I do in order to use Sweave with greek text flawlessly? One solution is to edit the .tex file produced by Sweave, but this solution is by far counter-productive. Thank you very much in advance, Constantine Tsardounis http://www.costis.name PS.: I am having no problem to run Sweave in 100% English texts. I postscript the following files: * unsuccessful.sweave.Rnw * unsuccessful.sweave.tex * successful.greek.tex ######################## unsuccessful.sweave.Rnw ######################## \documentclass[a4paper,...

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems
