lapack in R 2.11.1 (Ubuntu 10.04.1)
Hi there,
I'm trying to install the package RcppArmadillo in my R 2.11.1 which I installed
and regularly update via Ubuntu's repositories.
When I try to install RcppArmadillo from CRAN I get:
> install.packages('RcppArmadillo', lib='~/myRlibs')
[...]
g++ -shared -o RcppArmadillo.so RcppArmadillo.o fastLm.o
-L/home/matias/myRlibs/Rcpp/lib -lRcpp

R Crashes when using "large" matrices (Ubuntu 11.04)
Sorry for re-posting, but the original one ended up inside a previous and unrelated thread. -- Matias

Hello,
This simple SVD calculation (commands are copied
immediately below) crashes on my Ubuntu machine (R 2.13.0). However it
works fine on my Windows 7 machine, so I suspect there's a problem with
(my?) Ubuntu and / or R. Can anybody else reproduce it (with Ubuntu
11.04)? Thanks

Help Me to Adjust the R Code
Hi,
The following code, from Angelo Canty article on line "Resampling Methods in R: the boot Package, 2002", works fine for Angelo Canty using R 2.6.0 on Windows XP.
It also works for me using R 1.2.1 and S-PLUS 2000 on Windows XP after installing the S-PLUS bootstrap library, with slight differences in my outputs.

outer-question
Dear all,
This is a rather lengthy message, but I don't know what I made wrong in
my real example since the simple code works.
I have two variables a, b and a function f for which I would like to
calculate all possible combinations of the values of a and b.
If f is multiplication, I would simply do:
a <- 1:5
b <- 1:5
outer(a,b)
## A bit more complicated is this:
f <-

rgamma with rate as vector
Hi - I have a question about the following code from Bayesian
Computation with R (Jim Albert).
par(mfrow=c(2,2))
m = 500
alphas = c(5, 20, 80, 400)
for (j in 1:4) {
mu = rgamma(m, shape=10, rate=10)
lambda1 = rgamma(m, shape=alphas[j], rate=alphas[j]/mu)
lambda2 = rgamma(m, shape=alphas[j], rate=alphas[j]/mu)

help, bifurcation diagram efficiency
Hello all -
This code will run, but it bogs down my computer when I run it for finer and
finer time increments and more generations. I was wondering if there is a
better way to write my loops so that this wouldn't happen. Thanks!

Viable Approach to Parallel R?
All,
We are researching approaches to parallel R with the end goal of running
R in a distributed manner on a Linux cluster. We expect of course to do
some work decomposing our problems to be task-parallel or data-parallel,
but wouldn't mind getting an initial boost working with "embarrassingly
parallel" code sections and one of the approaches below.

Glm
Hi,
Is there any way to estimate a DEPENDENT variable through a GLM/LM model?
Suppose I have the linear model: y=a0+a1*x1+a2*x2 (a0=1, a1=0.6, a2=0.8,
x1~N(1,1), x2~N(0,1)).
The alphas and the auxiliary variables are given and I have to estimate y.
The point is if I estimate it, let¹s say algebraically, I get high variances
that do not decrease as sample sizes increases... Is the any other way

Problem with ARCH
Hi
I have a problem on how to proceed with further steps in my analysis. I did
a linear OLS regression (ri,t=alpha*beta*rm,t+et) with my daily data of
stock and index returns. There is now the problem of arch in my error terms.
Thus I used the following r command:
/garch(resid_desn, order=c(0,2)) ## This ARCH(2) process seems to fit the
best after trial and error. Consequently, I get there

R-beta: Dec alpha
R ran find on our Sun until it was stolen. I have now set up R on one of
our Dec Alphas OSF1 V4.0 386. R-0.49 configures builds and runs fine
except that the glm command crashes R. R-0.60.1 configures builds and
runs until a cis entered. I think the problem is the floating point
conventions but before I get in over my head a question
Has anyone used glm successfully on Alphas OSF1 V4.0 386?

Classification Trees
I apologize if you receive multiple copies of this letter. This is the first time I've written to this mailing list, so please be kind:-)
Hello everyone!
I'm trying to make a programme which grows a classification tree. I use APL programming language and I use R to compare and test results.
I have a classification tree and I have a sequence of cost-comlexity parameters(alphas):

p-values
Dear All,
When I run rlm to obtain robust standard errors, my output does not include
p-values. Is there any reason p-values should not be used in this case? Is
there an argument I could use in rlm so that the output does
include p-values?
Thanks in advance,

1.0-test57
http://dovecot.org/test/
Two important fixes:
- Fixes the recently reported dovecot-auth crashes with unexpected
client input
- Fixes mbox corruption in some not-so-common cases. Hopefully this is
the last one. I added more asserts anyway which try to catch similiar
mistakes and avoid losing data.
Others:
- Added oe-ns-eoh workaround for pop3. Fixes outlook/netscape problems
with buggy
