Hello, I have a matrix equation, Ax=b, that I need to solve for x. x should be a vector of positive numbers (between 0 and 1). A is not a square matrix in general. This lead me to using the SVD. However, using the SVD gives me positive and negative numbers, as well. I have some constraints included in the A matrix itself (i.e., that the sum of some xi should be equal to 1) but I do not know how

Hi In a nutshell, the BindAddress functionality doesn't seem to work (at least on Solaris 7 when using the fake-gettaddrinfo module provided). I haven't been able to test on other OS versions or using an OS library provided getaddrinfo (such as OpenBSD), but the unless the functionality of getaddrinfo is majorly different, I think this problem would be similar everywhere. The code in

I am using R in Windows. I see that I will have to use batch processes with R. I will have to read and write text files, and run some R code; probably some external code too. I have never done scripting. Is there any document that explains simple steps with examples? I also have heard that Python is a good scripting language. Is it worth the effort? (I do not have too much free time, so if I could

Dear R Users, I want to make a call from R into C++. My inputs are List1, List2, List3, IntegerID. The amount of elements of the lists and their type depend on IntegerID. Typical elements of a given list can be vectors, doubles, and even other lists. I want to return also a list (whose nature will depend also, possibly, on IntegerID). What I want to do is to call these 4 inputs from C++ and then

Dear list users, I need to learn about MCMC methods, and since there are several packages in R that deal with this subject, I want to use them. I want to buy a book (or more than one, if necessary) that satisfies the following requirements: - it teaches well MCMC methods; - it is easy to implement numerically the ideas of the book, and notation and concepts are similar to the corresponding R

Dear R users, I am having problems building R packages in Windows xp. I have followed the instructions from Peter E. Rossi in Documentation -> Other, except for the TeX version (fpTeX), since when I go to the recommended webpage, it is said that fpTeX has been discontinued. I have MikTeX in my computer, and I have followed the recommendations in

Hello to everybody, I have a quadratic programming problem that I am trying to solve by various methods. One of them is to use the quadprog package in R. When I check positive definiteness of the D matrix, I get that one of the eigenvalues is negative of order 10^(-8). All the others are positive. When I set this particular eigenvalue to 0.0 and I recheck the eigenvalues in R, the last
