Hi, I am starting tu use R on a linux environment (Red Hat 6.0), and when I tried to use library MASS, writting library(MASS) I got the following message: > library(MASS) Error: dynamic library `MASS' not found > Is there something I am doing wrong?

Hi everyone, I am interested in estimating this type of random effects panel: y_it = x'_it * beta + u_it + e_it u_it = rho * u_it-1 + d_it rho belongs to (-1, 1) where: u and e are independent and normally zero-mean distributed. d is also independently normally zero-mean distributed. So, I want random effects for group i to be correlated in t, following an AR(1) process. I am

Hello, I would like to know whether is possible to install R in a Itanium 64 bits computer. We cannot neither compile source code because we have Intel compilers. Specifically, we have an Intel Itanium II, Linux Red Hat 64 bits and Intel Fortran and C compilers: ifort, icc.

I would like to know if someone has done work on trees with multivariate response. I need something like rpart but for vector responses. If someone has code that he/she is willing to share, I would be grateful. If not, even guidelines for writing my own starting from rpart would be welcomed. ft. -- Fernando TUSELL e-mail: Departamento de

I've installed fail2ban, it seems to be working as it identified my failed test logins, BUT, my question is: what can I do when I see same invalid name trying to login to dovecot, different IP each time, how can I say block each IP as used by this name ? or it that a bad idea ? I can see two persistent attempts as so: I don't have such user 'ignacio' or 'julian' # grep

Hi, I'm trying to set up a prediction software, now i testing the performance of my method, so i need to calculate a ROC curve, specially auc, cut-off, sens and spec, i just looking at ROCH package, but it's a mass for me, i'm not a math guy and I'm getting lost Could any of you recommend me an easy-to-use package to do this task? i just have a list of positive/negative samples

Dear User, I got the following error running a regression quantile: > rq1<-rq(dep ~ ., model=TRUE, data=exo, tau=0.5 ); > summary(rq1) Erro em rq.fit.fnb(x, y, tau = tau + h) : Error info = 75 in stepy: singular design Any hint about the problem?

Dear R-Users, How can I compute simple moving averages from a time series in R? Note that I do not want to estimate a MA model, just compute the MA's given a lenght (as excel does).

Dear R Users, Did someone implemented the R1 (Pseudo R-2) and likelihood ratio statistics for quantile regressions, which are some of the inference procedures for quantile regression found in Koenker and Machado (1999)? I tried the Ox version, but my dataset is too large (> 50.000) and the algorith breaks. ________________________________________ Ricardo Gonçalves Silva, M. Sc. Apoio aos

Dear Users, I loaded my dataset as following: presu <- read.table("C:/_Ricardo/Paty/qtdata_f.txt", header=TRUE, sep="\t", na.strings="NA", dec=".", strip.white=TRUE) dep<-presu[,3]; exo<-presu[,4:92]; When I try: rq(dep ~ exo, ...) or mle.stepwise(dep ~ exo, ...) I got the same error: > rq(dep ~ exo) Error in model.frame(formula, rownames,

Hi, I load my data set and separate it as folowing: presu <- read.table("C:/_Ricardo/Paty/qtdata_f.txt", header=TRUE, sep="\t", na.strings="NA", dec=".", strip.white=TRUE) dep<-presu[,3]; exo<-presu[,4:92]; Now, I want to use it using the wls and quantreg packages. How I change the data classes for mle and rq objects? Thanks a lot,

I'm unable to configure asterisk to provide dial tone, busy tone, detect dtmf digits, etc to an analog phone connected to a FXS port. Unfortunately, this particular hardware does not provide FXO signaling. Incoming calls work perfect, the phone rings and voice flows on both directions. However, I can't place outgoing calls, there is no dial tone and dialing out makes no difference.

Alvaro Munoz (Hopkins Epi) is patenting the "diamond graph". http://www.jhsph.edu/Press_Room/Press_Releases/Munoz_diamond_graph.html There is enough prior art (hexagonal binning, among others) to make this amusing, except that it probably will get a patent. It's a reasonable graphical technique, but patentable? best, -tony -- A.J. Rossini rossini at u.washington.edu

Below the line is (slightly edited, to remove irrelevant stuff) the transcript of a session in R. Seems that data is read in, but I cannot print or use it. I have looked inside the data directory of MASS, and see that the format of the data is different than the one from other libraries I have. It may be that this particular format is not read correctly, or my setup may be faulty. I

Hi Jim, I did what the doc says but the problem is the same. Does anybody saw this work ? I mean, is the Samba 3.0.2a+Kerberos MIT 1.3.3 able to be accessed by a WXP, W2K or W2K3 machine, using Kerberos tickets generated in a Windows 2003 KDC (W2K3 AD) ?

Dear R-help readers, In R 1.8.1 it was easy to print the documentation for recommended packages: go to the full reference manual (refman.pdf) and print the relevant pages, which were contiguous. With R 1.9.0 some of those packages (e.g. "ts") have become part of the "stats" package, and hence their documentation is scattered throughout that of the other component packages of
