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

Calculating Sensitivity, Specificity, and Agreement from Logistics Regression Model
...ssume 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"?
Thanks

Support Vector Machine
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?
Thanks

Problem with misclass function on tree classification
...e "tr, when I write "misclass(tr,x$test)" as shown in the link
I get an error message that "R does not find the function pred1.tree".
Is this function included in the tree package? If so it was not in my download. Is this a bug?
Do you know of a fix?
Thanks for your help

Can I have more than 1 bridge attached to a KVM
...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 ; bridge=br0 bridge=br1 - never worked.....
Thanks so much,
Meir

Appropriateness of survdiff {survival} for non-censored data
...st often dealing with censored data and that
survival analysis, at least in the package survival, is largely built
around these conventions and differs from a classical biological
perspective. For example, for lifetable analysis of insects there is
often no need to estimate survival using a Kaplan-Meir estimate
because it is relatively easy to follow a cohort of individuals
through the entire course of life. Thus I question the
appropriateness of using survdiff in my analysis; I have exact data
yet I would be testing on the Kaplan-Meir estimate of these data in
survdiff. Thanks for any help.

Array element is function of its position in the array
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:

Weibull and survival
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...

Binary outcome with non-absorbing outcome state
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 subjects who fall more than
once. I would appreciate suggestions about a models that I could use,
how I would quantify the follow-up time, how I account for the imbalance
in the data (some subjects would cont...

Decision Function of Support Vector Machine
...w 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 I right how should I compute it? Is b output?
Thanks

Kill invertor on Powercom 1000VA
...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?
Thanks!!

Winbind Offline Login
...ogs back on, they
cannot access shares on the Samba Domain Member anymore.
I realise that "winbind offline logon" mentions that it is for local pam
logons to the Samba Server itself.
Is there any other way to allow cached access to shares on the Samba server
in Office B?

Shutdown problem with Mecer 1000VA Online UPS
...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.
I looked at the code, but don't understand enough to help.
Please let me know if I can be of any assistance.

Shutdown problem with Mecer 1000VA Online UPS
...if (strncmp(buf, "(ACK", 4)) {
..this should do the trick.
However, your UPS seems to speak an idiom that's more akin to the one
covered by the voltronic drivers (i.e. the (ACK/(NAK replies) -
available in the github repo - so maybe they're worth a try.
