No. But it has not been posted either. You got that message because you sent your message to the wrong address. You should have sent it to r-help at r-project.org You had probably sent it to r-help-request at r-project.org which would have had the effect that the server would have tried to interpret the contents of you message as commands (e.g. to unsubscribe, change your subscription

Dear R-users, I am currently writing an R package that contains three C++ files in the src/ source directory When i issue a R CMD check pkge_name, all the *.cpp files in the src/ directory will be compiled through something like (seen in 00install.out file): * Installing *source* package 'pkge_name' ... ** libs g++ -I/usr/lib/R/include -I/usr/lib/R/include -I/usr/local/include -c

Dear all, I am working on a 64 bits Linux system.

Dear R users, When i call the wireframe function from within a tcltk widget, it does not work. Here is a sample program that shows the bug. When you try: is.it.a.bug() You can see that the "curve" instruction is run but not the "wireframe" one. Do you have an explanation about this point?

hi, as I'm using R at Dell (where I am working), I manage to install packages from web, but there is a web proxy, which is pretty boring. R asks me to enter an active directory login/password, that would normally auth me through the web proxy, but it doesn't work. I'm looking forward for your help. Sorry if I used bad english. Any ideas ? Laurent -- «Un peu d'internationalisme

Hello, Is there an accepted way to convey, for regression trees, something akin to R-squared? I'm developing regression trees for a continuous y variable and I'd like to say how well they are doing. In particular, I'm analyzing the results of a simulation model having highly non-linear behavior, and asking what characteristics of the inputs are related to a particular

I am working with Solaris 2.6 and with the version of openssh 2.9.9-p2 I was able to compile for a UltraSpar 5 Sun4u with no problem. But fot a Sparc4 Sun4m i'm getting this message: ./ssh : Exec format error. Wrong Architechture. Do you have a hit why it's not working, is there and option i have to set? thank you for your help jean ============================================ Jean

Greetings, I am working on creating an interactive website that will generate R-code for users based in the information they input on the site. Currently, the R-code can be generated and downloaded to be run locally on a computer with R. However, I have noticed a number of applications out there that instead submit the code directly to an R-web server. Some examples seem to be:

Hello list, Sorry, these questions are not directly linked to R. If I consider an indefinte real matrix, I would like to know if the symmetry of the matrix is sufficient to say that their eigenvectors are real ? And what is the conditions to ensure that eigenvectors are real in the case of an asymmetric matrix (if some conditions exist)? Thanks in Advance, St?phane DRAY

Hello, suppose I have a list with matrices: a=list(x1=matrix(rnorm(10),5,2),x2=matrix(rnorm(10),5,2),x3=matrix(rnorm(10),5,2)) I want to compute for all combination of xi and xj (x1,x2 x1,x3 and x2,x3) a value. This value is given for the pair x1,x2 by trace(x1%*%t(x1)%*%x2%*%t(x2)) / trace(x1%*%t(x1))*trace(x2%*%t(x2)) I know that product matrices t(xi)%*%xi can be obtained by:

Hello List, I would like to orthonormalize vectors contained in a matrix X taking into account row weights (matrix diagonal D). ie, I want to obtain Z=XA with t(Z)%*%D%*%Z=diag(1) I can do the Gram-Schmidt orthogonalization with subsequent weighted regressions. I know that in the case of uniform weights, qr can do the trick. I wonder if there is a way to do it in the case of non uniform

Hi, I tried running Rcmd.exe to no avail. It doesn't even start because it tries to read some memory address that NT says it can't and terminate. I tried downloading and reinstalling rw1020sp.zip with the installer twice just in case it got corrupted somehow in transport but it resulted in the same problem. What should I do? platform i386-pc-mingw32 arch x86 os Win32 system

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Bonjour, I have two monitors and an nvidia graphic card. I uses the nvidia proprietary driver from rpmfusion and have configured the system to use the twinview option. I need to load an icc profile for each screen (they are not exactly the same) and this seems to be impossible under this configuration.... Am I right? So I changed my config:

Hi, If I may suggest that something be done to the window drawing function of a plot. As it is now, we don't even have time to resize the window by a tiny bit before it's invoke and I think it would be an improvement if while the mouse is down the redrawing was delayed somehow. This is especially true when the plot is crowded. I also observed that moving the plot window around was a lot

Hi, In view of the problems I was having with DomU network timeout after a live migration (I posted that problems here a while ago but never got anything except from private emails) I finally updated my Debian/Squeeze Dom0s last night to a new kernel, from 2.6.32-23 to 2.6.32-26. Now live migration just hangs...Any ideas? Xen-related Debian packages (all from Debian repositary, except drbd

Hi, I am trying to forward calls to another * server with IAX Here is What I want to Do 1- Call SERVER1, let say at 51412345678 2- SERVER1 should transfer the call to SERVER2 in a remote location 3- SERVER2 Receive the call and transfer it to the PSTN number. I have one X100P card on each machine. What is happening is that when the remote party picks up the phone, all he can hear is a weird

Hello list, I have two vectors x and x2: x=runif(10) x2=runif(10) and one vectors with their names : my.names=c("x","x2") I would like to cbind these two vectors using their names contained in the vector my.names. I can create a string with comma ncomma=paste(my.names,collapse=",") and now, I just need a function to transform this string into a adequate

To whom it may concern, I try to simulate a non-normal multivariate distribution. The MASS package allows by mean of "mvrnorm" command to perform a multivariate normal simulation. Is there an equivalent command for an arbitrary multivariate distribution available in the R-language? Thank you in advance.
