Hello, maybe this info is helpful for someone else, at least it is a reminder for me if the problem should reoccur: The last hours R drove me nuts because it wouldn't install new packages, or more irritating still: It would chose randomly which packages to install when given a list ("unable to move temporary installation" ). The solution was to turn of the indexation of

Hi all, this should be a simple question, but I haven't been able to do it right. I am trying to download multiple stock quotes in a loop, so that every timeseries is safed with the symbol of the stock. Can anybody help me out? Here's the code: require(tseries) startd <- "2000-06-01" stocks <- c("bmw.de", "vow.de", "dte.de") for(stock in

Hi, when I try installing new packages (in this case DBI) I run into the following problem: Paket 'DBI' erfolgreich ausgepackt und MD5 Summen abgeglichen Warnung: kann tempor?re Installation 'C:\Programme\R\R-2.7.0\library\file5f906952\DBI' nicht nach '? xlD?? $@\R\R-2.7.0\libra' verschieben Has anybody any idea where these strange symbols come from? Thanks in

Hello, I want to write a data.frame with 10 different entries x (by index y)? into ten different csv-files. In every output file should be one of the ten numbers of x. I tried this one, but I can't write into ten different files, like test1.csv to test10.csv: x <- rnorm(10) y <- c(1:10) z <- data.frame(y,x) n <- nrow(z) for (i in 1:n) write.csv(z$x[i],

Hi, we have a debian etch system running here and it works fine for hvms (winxp) and paras (debian etchs). Today i tried to do a SLES10SP2 setup as hvm (in the future it should run as para). I used this config: --------------- xenserver:/etc/xen# cat gp2backuptest.cfg kernel = ''/usr/lib/xen-default/boot/hvmloader'' builder = ''hvm''

Dear All, I am wondering on how to use the abline.xyplot with xyplot such that I will have different vertical lines for each panel. More sepcifically, suppose that the xyplot generates 4 panels defined by the combination of two binary variables: X_1 and X_2. i.e. xyplot(Y ~ Z | X_1*X_2, data = df) I want something like: abline(v = 5) if X_1=0 and X_2 = 0 abline(v =

Hi All Apologies if this is not the correct list for this question. The Rglpk package offers the following example in its documentation library(Rglpk) ## Simple mixed integer linear program. ## maximize: 3 x_1 + 1 x_2 + 3 x_3 ## subject to: -1 x_1 + 2 x_2 + x_3 <= 4 ## 4 x_2 - 3 x_3 <= 2 ## x_1 - 3 x_2 + 2 x_3 <= 3 ## x_1, x_3 are non-negative integers ## x_2 is a non-negative real

Hi all, I'd like to fit a multivariate regression with the variance of the error term porportional to the predictors, like the WLS in the univariate case. y_1~x_1+x_2 y_2~x_1+x_2 var(y_1)=x_1*sigma_1^2 var(y_2)=x_2*sigma_2^2 cov(y_1,y_2)=sqrt(x_1*x_2)*sigma_12^2 How can I specify this in R? Is there a corresponding function to the univariate specification lm(y~x,weights=x)??

Dear R-Users, I need to find a smooth function f() and coefficients a_i that give the best fit to y ~ a_0 + a_1*f(x_1) + a_2*f(x_2) Note that it is the same non-linear transformation f() that is applied to both x_1 and x_2. So my first question is how can I do it in R? A more general question is this: suppose I have a utility function U(a_i, f()), where f() is say a spline. Is there a general

Dear R-users, i try to solve to following linear programm in R 0 * x_1 + 2/3 * x_2 + 1/3 * x_3 + 1/3 * x_4 = 0.3 x_1 + x_2 + x_3 + x_4 = 1 x_1, x_2, x_3, x_4 > 0, x_1, x_2, x_3, x_4 < 1 as you can see i have no objective function here besides that i use the following code. library(lpSolve) f.obj<-c(1,1,1,1) f.con<-matrix(c(0,2/3,1/3,1/3, 1,1,1,1,

Dear List: I cannot seem to find a way to plot my data correctly. I have a small data frame with 6 total variables (x_1 ... x_6). I am trying to plot x_1 against x_2 and x_3. I have tried plot(x_2, x_1) #obviously works fine plot(x_3, x_1, add=TRUE) # Does not work. I keep getting error messages. I would also like to add ablines to this plot. I have experimented with a number of other

Dear All, Here is what I am trying to achieve: I would like to plot some data in 3D. Usually, one has a matrix of the kind y_1(x_1) , y_1(x_2).....y_1(x_i) y_2(x_1) , y_2(x_2).....y_2(x_i) ........................................... y_n(x_1) , y_n(x_2)......y_n(x_i) where e.g. y_2(x_1) is the value of y at time 2 at point x_1 (see that the grid in x is the same for the y values at all times).

Hii, Can anybody help me, I don't know how to print the "median".

Dear R experts, I was wondering if there are any R functions that give the tail area of a sum of chisquare distributions of the type: a_1 X_1 + a_2 X_2 where a_1 and a_2 are constants and X_1 and X_2 are independent chi-square variables with different degrees of freedom.

Apart from religious grounds (!), is there any pros or cons why I should choose one over the other for a new install of asterisk ? Julian

Hi there! Today I tried to estimate models using both plm and pgmm functions, with an interaction between X1 and lag(X2, 1). And I notice two issues. Let "Y=b_1 * X_1 + b_2 * X_2 + b_3 * X_1 * x_2 + e" be our model. 1) When using plm, I got different results when I coded the interaction term with I(X1 * lag(X2, 1)) and when I just saved this multiplication X1 * lag(X2, 1) in a

Hello together, we try to setup a samba domain controller with LDAP and roaming profiles for Win7-Clients. Everything looks fine last Friday but today the clients did not longer save changes to the profiles. There is no error in samba log and also no in the windows log. If I delete a profile from a client it is loaded correctly at next logon, but the changes are not saved at logout. Windows XP
