Factors.
Hello,
I'm new with R. I need some help; I have a matrix of data to wich i want to
apply the function dudi.acm to perform multiple correspondence analysis.
However to use it all variables must be factors, so how can i turn each column
of the matrix into a factor? I've tried as.factor. It works isolated for each
column, but when I form the matrix of all factors it doesnt work.
Please

How to use PVH mode in xen
Hi,
I'm instresting with the PVH mode, is there any wiki available to boot up a PVH guest?
I used the following source code to compile the xen and dom0.
I have tried adding pvh=1 in xl.cfg file as pv mode, but guest still uses qemu device model.
This patch series can also be pulled from this git tree:

problem with convergence in mle2/optim function
Hello R Help,
I am trying solve an MLE convergence problem: I would like to estimate
four parameters, p1, p2, mu1, mu2, which relate to the probabilities,
P1, P2, P3, of a multinomial (trinomial) distribution. I am using the
mle2() function and feeding it a time series dataset composed of four
columns: time point, number of successes in category 1, number of
successes in category 2, and

model selection with spg and AIC (or, convert list to fitted model object)
Dear R Help,
I have two nested negative log-likelihood functions that I am optimizing
with the spg function [BB package]. I would like to perform model
selection on these two objective functions using AIC (and possibly
anova() too). However, the spg() function returns a list and I need a
fitted model object for AIC(), ICtab() [bbmle package], or anova().
How can I perform AIC-based model

Errors in Integrate
Hello,
I have written the function I would like to integrate in two ways:

pp <- 1-pnorm(yy/sqrt(vv))
part1 <- pp^(a2-1)
part2 <- (1-pp)^(b2-1)
part3 <- dnorm(yy,mu2,sqrt(vv))
return(part1*part2*part3) }

pp <- 1-pnorm(yy/sqrt(vv))

Solving two nonlinear equations with two knowns
Dear R users,
I have two nonlinear equations, f1(x1,x2)=0 and f2(x1,x2)=0. I try to use optim command by minimize f1^2+f2^2 to find x1 and x2. I found the optimal solution changes when I change initial values. How to solve this?
BTW, I also try to use grid searching. But I have no information on ranges of x1 and x2, respectively.
Any suggestion to solve this question?
Thanks,

How does this function print, why is n1 which equals 1 printed as 2?
Windows 7, R 2.12.1
Colleagues,
I am trying to understand the n.for.2means function. The code below is a copy of the function (renamed to n.for.2means.js). I have inserted a single line of code towards the bottom of the function which uses the cat function to print the value of n1. You will note the value (preceded by stars) is printed as 1.
The function (1) prints a lot of output without any

Estimating parameters of 2 phase Coxian using optim
Hi,
My name is Laura. I'm a PhD student at Queen's University Belfast and have
just started learning R. I was wondering if somebody could help me to see
where I am going wrong in my code for estimating the parameters [mu1, mu2,
lambda1] of a 2-phase Coxian Distribution.
cox2.lik<-function(theta, y){
mu1<-theta[1]
mu2<-theta[2]
lambda1<-theta[3]
