Hi all, Suppose I have a vector x with numerical values. In y, I have a categorial variable : y<-c(1,1,..2,2,...30,30,30) x and y have the same length. I would like to compute the mean for x for the modality 1 to 30 in y. mean(x[y==1]),...,mean(x[y==30]) I do not want to use an iterative procedure such that for (i in 1:30).. Thanks for your help, Regards. Olivier. --

Dear everyone, I am new in R and I've got difficulties in realizing the following tasks: -I have variables (factors) with different numbers of levels, either 1, 2 or 3. -I have a matrix containing these 204 factors and I have to correlate them by groups of 4 variables. -I have to delete the factors just having one level ( because when correlating one-level factors, the output is NA) here

Hi, I've been using R for a few weeks now, but consider myself still a newbie, especially in what concerns the basics of data handling in R. My situation is this: I read in data from a database using RODBC, and then use "table" to produce a table of "counts per years", table which I give to "plot". All is well, as long as there are no gaps in the years

Hello, (Power Book G4, Mac OS X, R 2.5.0) I would like to repeat the function range for 85 Vectors (V1-V85). I tried with this code: i<-0 > repeat { + i<-i+1 + if (i<85) next + range (Vi, na.rm = TRUE) + if (i==85) break + } I presume that the Vi is wrong, because in this syntax i is not known as a variable. But I don´t know how to say that it is a variable here. Would be nice if

Ned, Thank you very much for the response. Great example following through on the premise. It sounds like I need to have a better understanding of the traffic patterns on my network to know the optimal order for iptables filtering rules. My brief example - Premise: I want to limit outsiders from interfering with LAN client machines. So, I have the following rules regarding forwarding traffic:

Dear all, I would like to import a range of cells (e.g. F10:K234) from an Excel worksheet to R. I have looked for documentation on RODBC and RDCOMClient but I was not able to find enough information to solve my problem and all the examples I have seen were dealing with an entire worksheet, not a range of cells. Thanks, Jean-Noel Jean-Noel Candau INRA - Unit? de Recherches Foresti?res

Dear all, I would like to perform a regression tree analysis on a dataset with multicollinear variables (as climate variables often are). The questions that I am asking are: 1- Is there any particular statistical problem in using multicollinear variables in a regression tree? 2- Multicollinear variables should appear as alternate splits. Would it be more accurate to present these alternate

This module does basically what I have done in the very beginning. Create an empty directory as a preparation step for the configuration files. But this configuration also did not regenerate the files. Seems, I will stick with my workaround and delete the files manually and the restart the Puppet agent. If anyone is interested in details, see: http://wp.me/p1RukY-1n. Thanks for helping, Gabriel!

Hello all, I have a vector of character strings, in which I have letters, numbers, and symbols. What I wish to do is obtain a vector of the same length with just the numbers. A quick example - extract of the original vector : "lema, rb 2%" "rb 2%" "rb 3%" "rb 4%" "rb 3%" "rb 2%,mineuse" "rb" "rb" "rb 12"

Hello all, I am trying to write a script that will check logs for puppet errors to use in a nagios check. I am checking /var/log/messages (RHEL6) but when puppet runs on its 30 minute interval, nothing gets written to messages. I have also looked at /var/log/puppet/puppet.log but that does not seem to be consistent either: [root@gm10v nagios]# tail /var/log/puppet/puppet.log Wed May 02 14:27:47

Hi, system info: ubuntu 7.04 (Host OS) samba 3.0.24 (installed with apt-get) vmware-server 6.0.1 windows XP (Guest OS) I was using the iptables script provided by iptablesrocks.org.

I have set up puppet on Ubuntu/Debian servers with no problem. I am trying to get puppet working in a RHEL environment. I have the client installed and the certificate is signed so I know the two are talking but for some reason I can not get puppet to push the file on to the client. What am I missing? OS - RHEL5.7 Installation Source - epel-testing repo Puppet server version - 2.6.6 puppetd

Getting rid of netbios does not mean you should not configure it. You "should" configure it. And even if you disable WINS, LLMNR is still running, so you gained.. .. Nothing with disabling WINS.
