Cross-checking a custom function for separability indices
Hi list!
I have prepared a custom function (below) in order to calculate separability
indices (Divergence, Bhattacharyya, Jeffries-Matusita, Transformed divergene)
between two samples of (spectral land cover) classes.
I need help to cross-compare results to verify that it works as expected
(since I don't know of any other foss-tool that will give me quickly some
results).
Does anybody

ROC curve with survival data
Hi everyone,
I am doing 5 years mortality predictive index score with survival analysis using a Cox proportional hazard model where I have a continous predictive variable and a right censored response which is the mortality, and the individuals were followed a maximum of 7 years.
I'd like to asses the discrimination ability of survival analysis Cox model by computing a ROC curve and area

How to disable output messages (prints or cats) from functions in R?
Hi everybody,
I have to use a function that shows an output message like "# nonzero
coefficients ..." followed with a lot of numbers depending on the input.
This is very annoying because I have to run that function several times
and I don't want to show this information.
What I want is to disable that display but I don't know how to do it.
I've tried it with

get data from Perl arrays
Hi,
a very simple doubt, but I do not know how to manage this.
I want to plot a histogram for all data in 'datos.txt'.
a) by using R:
datos<-scan("datos.txt")
pdf("xh.pdf")
hist(datos)
dev.off()
b) How could I invoke R inside Perl to do the same??
#!/usr/bin/perl
open(DAT,"datos.txt");
while (<DAT>) {
chomp;
push(@datos,$_);
}

GLM & ANOVA
Hola a todos,
Estoy trabajando con modelos lineales generalizados (GLM), en
particular con las funciones glm y anova.glm de R. Tengo una pregunta
que es más bien técnica en el sentido estadístico (y un poco Off Topic
y probablemente un tanto naive). No tengo claro si es correcto decir
análisis de varianza o de devianza al utilizar GLMs, veo que en el
help de anova.glm dice análisis de

sambaRefuseMachinePwdChange policy
Hi,
we have a couple of Linux RHEL 5 samba servers in a domain, one as PDC
and the other as BDC, and both with LDAP backends
samba version is 3.0.28-1
We want pc clients can't change their machine password using
sambaRefuseMachinePwdChange policy, so we set it to 1 in LDAP
But pc clients still can change their passwords, and we don't see any
acces to sambaRefuseMachinePwdChange

IPMI serial console
Hi all,
A recent thread inspired me to try getting a proper serial console working on a Supermicro X9SCL motherboard with IPMI.
However I find that while I see loader messages and the getty I enabled after boot I don't get any kernel messages which does somewhat limit the utility..
The BMC creates COM3 (/dev/cuau2) which works with getty. I modified /boot/loader.conf like so..

Is there any multivariate regression function to combine all variables from a dataset?
Hi everybody,
I've been looking for a function that combines all variables from a
dataset because I need to do multivariate regression.
If we have linear regression with an expression like f(x) = a0 +
sum(ai*xi) what I want to do is something like f(x) = a0 + sum(ai*xi) +
sum(sum(bij * xi * xj)) + sum(sum(sum(cijk*xi*xj*xk))) + ...
So I need a function that combines all the values from
