Lets say I have a vector as follows xx<-rnorm(20) How could I find the indices of the vector<0?

Hi, Assume I have a variable Y having two discrete values and two predictor variables x1 and x2. I then do a logistic regression model fit as: fit<-glm(Y~x1+x2,family=binomial). Are there functions in R than calculate the Sensitivity, Specificity , and Agreement of the model "fit"?

Hi, I would like to try using a Support Vector Machine on a classification problem that I'm dealing with. Does such a package exit in R?

I am working through Tom Minka's lectures on Data Mining and am now on Day 32. The following is the link: http://alumni.media.mit.edu/~tpminka/courses/36-350.2001/lectures/day32/ In order to use the functions cited I followed the instructions as follows: Installed tree package from CRAN mirror (Ca-1) Downloaded and sourced the file "tree.r" Downloaded the function

Hello Everybody, I have a physical machine with 4 Ethernet cards that I have mapped to 4 bridges. I would like to have each of my KVMs use 2 bridges for NIC bonding. 1. Can I have more than one bridge assign to one KVM? 2. Can I use virt-install to assign a KVM with more than one bridge during the KVM installation? a. It was a long shot but I have tried bridge=br0,br1 ;

Hi, We have a Linux (RHEL 3.0, update 3) Samba 3 server which worked fine for months but suddently have trouble to keep its trust with the DC server. The only way to recover is to reset the machine account from the Windows DC side and do a "net join" to the domain from the Linux side. The Linux machine is able to keep its "trust" with the domain exactly 7 days, which,

speex_preprocess() isn't covered in the manual, is it? But, it's very easy to use. If it returns non-zero, voice was detected.

Hello, I would like to have a One XEN read only image to be shared among many physical machines. I would also need to have a writable file system for /etc /var and /tmp. How can I do that?

I read through Harrington and Fleming (1982) but it is beyond my statistical comprehension. I have survival data for insects that have a very finite expiration date. I'm trying to test for differences in survival distributions between different groups. I understand that the medical field is most often dealing with censored data and that survival analysis, at least in the package survival,

I want to create a new array which selects values from an original array based on a function of the indices. That is: I want to create a new matrix Vnew[i,j,k]=Vold[i,j,ks] where ks is a function of the index elements i,j,k. I want to do this WITHOUT a loop. Call the function "ksfunction", and the array dimensions nis,njs,nks. I can do this using a loop as follows: # Loop version:

Hi I have been asked to provide Weibull parameters from a paper using Kaplan Meir survival analysis. This is something I am not familiar with. The survival analysis in R works nicely and is the same as commercial software (only the graphs are superior in R). The Weibull does not and produces an error (see below). Any ideas why this error should occur? My approach may be spurious.

I am trying to model data in which subjects are followed through time to determine if they fall, or do not fall. Some of the subjects fall once, some fall several times. Follow-up time varies from subject to subject. I know how to model time to the first fall (e.g. Cox Proportional Hazards, Kaplan-Meir analyses, etc.) but I am not sure how I can model the data if I include the data for those

Hi, As a number of people suggested, I downloaded the "e071" package and am using the function "svm" for my classification problem. I now want to take the classifier outside the R environment, for example to a C program, and use it. I know that the classifer is of the form WTX+b where W is defined by the support vectors. I did not see that W vector is output from svm. If am

...the default) I've stared the code for usbhid-ups.c for a while, but apart from seeing that the UPS uses "special bits" in the shutdown time I am no further (my C knowledge sucks!) I am prepared to assist with debugging the protocol if neccesary. Any advice?

...DE I modified /etc/init.d/nut-server to call my script instead of upsdrvctl shutdown. This works, but I suspect the blazer driver must be fixed at some stage.
