(1) I have a master data frame that reads ClientID |date |value (2) I also have a control data frame that reads Client ID| Min date| Max date| control parameters The control data set may not have all client IDs . I want to use the control data frame on the master data frame to remove client IDS that don't exist in the control data set and for those that do, remove dates outside the

I've only recently started using R. One of the problems I come up against is after having extracted a large dataset (>5M rows) out of database, I realize I need another variable. In this case I have data frame with dates. I want to find the minimum date for each value of x1 and add that minimum date to my data.frame. > randomdf <- function(p) { data.frame(x1=sample(1:10^4, 10^p,

Using Asterisk-1.4.17, Zaptel-1.4.8, libpri-1.4.3 Upgraded this morning, now PRI channels are unstable as hell.

Hi there, I just tried out OpenSSH3.0p1 running on Solaris 8 with PAM (--with-PAM). The problem was mentioned some time ago and is still there :-( When a password is expired you are prompted to change it now, enter your login password and after doing so you are instantly disconnected. I think this is a problem with PAM and not SSH, but how can I get a solution on this ? sshd is running without

Hi, I'm having what I believe are OS problems with my installation of R-1.6.0. The machine I'm using was previously running R-1.4.0. The install seemed fine to me. I didn't note an error messages in 'make' or 'make check'. My problem is that I've been running some memory intesive code, and the code that ran under 1.4.0 but won't run under R.1.6.0 (or under

Dear all, after trying to compile R on our IBM Power3/AIX 5.1 machine I've been able to run it correctly. First of all I would thank all who responded my mails. I explain here how I've done it: First of all, it seems that configure and some shared libraries of AIX does not work at the same time. I tried to configure & make with the following environment vars CC=xlc F77=xlf CCC=xlC

Dear R user group, I'm looking for a robust mesure of correlation in R. I found a very interesting article by Dr Rich Herrington on http://www.unt.edu/benchmarks/archives/2001/december01/rss.htm and I'd like to implement exaclty this method but my problem is that everything is here developped in R language and is very slow when the correlation matrix is important. I'm wondering if

Excuse me. I don't understant how to use the function "stack". I'm not sure to know the good syntax. I've got a data witch column names are the time when the mesures was done and an other who indicates the age of the subjetcs. I would like to do a new matrix with patients older than a value and the new matrix will contain in the first column the time of the mesures and in

Hi. Samba 1.9.15p8 under IRIX 6.1 (yes I know, it's old stuff ...) The susers on Windows 9x/WindowsNT just put their strange file name or directory name (like /usr/people/mesure_?t? ) on the IRIX. However, from the IRIX side, it's impossible toaccess to such files/directory. What's more, my ARkeia backup client stalls on such a name and fouled up my backup database... NB: Oops: for

Hello R-List I use DClusters package (I work in a cancer regestry). I have 2 questions about it: 1-how is it possible to get back the bootstrap pValue? I mean the pValue of the calculated statistic with respect of the distribution of this statistic under the null hypothesis. 2-how is it possible to test an overdispersion in the poisson model? for choosing a best model I need this mesure of

Dear Yaya You will get more responses if you can post in English which is the language of the list. If you want advice about package choice you need to tell us what packages you have considered and rejected. You would also benefit from searching the CRAN Task Views - possibly the Psychometrics one might help you. If you want someone to send you code, as appears from your mail, you are out

Hello, I'm managing smaller private virtualization infrastructure, currently based on CentOS 7.x. In the past we were running mostly on Debian 7 (kernel 3.2.x) and CentOS 6.x without problems. After we have upgraded to CentOS 7.x, I have experienced occasional physical host crashes when I did e.g. suspend or resume more virtual machines OR random virtual machine checkpoint was invalid and VM
