Dear R listers, I posted this problem several days ago but it seems nobody answered. I use nlm to optimize a given function ,but it always generates the following warnings " Error in nlm(foo, theta.start) : non-finite value supplied by 'nlm' " I don't know why ,can anybody give me some hints ?? thanks in advance. regards .

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. thanks in advance _______________________ Jiang Peng, Ph.D. Candidate Department of Mathematics & Antai college of Economics and Management Shanghai Jiao

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

Dear R users, I need to add 0 in front of a series of numbers, e.g. 1->001, 19->019, Is there a fast way of doing that? Many thanks yan [[alternative HTML version deleted]]

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 yan

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] the

Can R invert a 160000x160000 matrix with all positive numbers? Thanks a lot!

Hi I am trying to use latest version of llvm and clang, and I have gotten them by svn. ./configure --enable-shared has run successfully, but make REQUIRES_RTTI=1 returns error: make[2]: Entering directory `/home/ryjiao/Downloads/llvm-dev/llvm/tools/llvm-config' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/home/ryjiao/Downloads/llvm-dev/llvm/tools/llvm-config'

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! :-) -bw

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 yan

Hi all, I'm Hao Liu, a 3rd year graduate student of Shanghai Jiao Tong University in China. We've build a project named JLLVM, and it's a java version of LLVM Core for Java developers.

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 " Error in
