optimization problem
Dear list,
hi !
I am a R beginner and I have a function to optimize .
alpha = argmin{ f(x,alpha) }
I want alpha to be in [0,1]. Is there any function that can work?
I use nlm() but i can't fix the domain of alpha.

[LLVMdev] Make error of latest devel version of llvm and clang
Hi Jiao,
Well, I didn't try to compile with RTTI, but I had some time ago a very
similar problem while linking the opt. In my case, I was not being able to
create the shared library when enable-shared were passed through the
configure script. I just had to realize that my default compiler was not
being able to generate the binaries, probably because of its version (it
was the stable llvm-gcc

I need to add 0 in front of a series of numbers, e.g. 1->001, 19->019,

R string help
Dear R guru:
If I got a variable
aaa<- "up.6.11(16)"
how can I extract 16 out of the bracket?
I could use substr, e.g.
substr(aaa, start=1, stop=2)
[1] "up"
But it needs start and stop, what if my start or stop is not fixed, I
just want the number inside the bracket, how can I achieve this?
Many thanks

function order
Dear All
I'm trying to sort a matrix using function order,
Some thing really odd:
e.g.
abc<-cbind(c(1,6,2),c(2,5,3),c(3,2,1))## matrix I want to sort
if I do
abc[ order(abc[,3]), increasing = TRUE]
the result is correct
[,1] [,2] [,3]
[1,] 2 3 1
[2,] 6 5 2
[3,] 1 2 3
But if I want to sort in decresing order:
abc[ order(abc[,3]), decreasing = TRUE]

[LLVMdev] 3.1 Has Branched
Hi all,
We branched for the 3.1 release! (Yay!)
If there are any fixes which you think should go into the release, please contact the code owners (http://llvm.org/docs/DeveloperPolicy.html#owners) so that they can approve the patches. No patches will be accepted into the 3.1 release without prior approval!
This should be a great release! :-)

function for grouping
Dear All,
I'm wondering if there is a R function could give me all the
combinations of the grouping/cluster result, given the number of the groups.
e.g.
3 objects: x1 x2 x3, number of groups is 2
so the result will be
group1:x1,x2; group2: x3
group1: x1;group2: x2,x3
group1: x1,x3;group2: x2
many thanks

a nlm() question
Dear R listers,
I have a very annoying problem using nlm().
I want to find the minimizer of my target function, if written in
\LaTeX is
f(\mu1,\mu2,\sigma1,\sigma2) = \sum_i^n( w_ig_t(z_i) ), where
g_t(z) is a pdf of bivariate normal distribution and z_i is my samples.
I cannot get the estimation result generated by nlm(), and I got
the following errors
