Dear list, this is not a problem report -- I would like to ask for advise what the recommended and safe way to perform the following is or what problems might arise in doing it differently. The question is: What is the recommended way of providing a default value in a prototype statement for a derived class for a slot provided from a parent class? I have first consulted the methods package

Dear R-users, I'm running an MLE procedure where some ODEs are solved for each iteration in the maximization process. I use mle2 for the Maximum likelihood and deSolve for the ODEs. The problem is that somewhere along the way the ODE solver crashes and I get the following error message: DLSODA- Warning..Internal T (=R1) and H (=R2) are such that in the machine, T + H = T on the next

Dear R-users I'm running a maximum likelihood procedure using the spg package. I'd like to save some output produced in each iteration to a file, but if I put the capture.output() within the function I get the following message; Error in spg(par = startval, fn = loglik, gr = NULL, method = 3, lower = lo, : Failure in initial function evaluation!Error in -fn(par, ...) : invalid argument

Hi there, I'm trying to solve 2 nonlinear equations in 2 unknowns using the BB package. The first part of my program solves 3 ODEs using the deSolve package. This part works. The output is used as parameter values in the functions I need to solve. The second part is to solve 2 equations in 2 unknowns. This does not work. I get the error message "unexpected end of input". So what

Greetings all, I am curious to know if either of these two sets of code is more efficient? Example1: ## t-test ## colA <- temp [ , j ] colB <- temp [ , k ] ttr <- t.test ( colA, colB, var.equal=TRUE) tt_pvalue [ i ] <- ttr$p.value or Example2: tt_pvalue [ i ] <- t.test ( temp[ , j ], temp[ , k ], var.equal=TRUE) ------------- I have three loops, i, j, k. One to test the all of

Hi all, I have to ask this and I know that the reason is that I am a newbie with R programming. So apologize if it is too obvious but I didn't find an answer after googling and reading "An introduction to R". So i have return data from 30 instruments and I am fitting a mixture of normal distributions for the asymmetric marginal distributions and then simulating from those

Colleagues, please help me with the simple question. How can I find R2 and p while doing best subsets regression? Also how can I see B and p for coefficients? Maybe you can advice me detailed manual, because in manual for the package this is not described. Thank you

Dear R-help, I have used the regsubsets function from the leaps package to do subset selection of a logistic regression model with 6 independent variables and all possible ^2 interactions. As I want to get information about the statistics behind the selection output, I?ve intensively searched the mailing list to find answers to following questions: 1. What should I do to get the statistics

I am running 1.3.1 on a Windows (NT 4.0) machine. I've fit a nonlinear model intended to predict crop yield from nutrient information, and want to use the profile function. If I type say, profile(simparj.fm) I get the following error message: "Error in prof$getProfile(): number of iterations exceeded maximum of 5.25515e-308" I used the profiler function to profile simparj,fm step

Hi, I have been using R for close to two years now and have grown quite comfortable with the language. I am presently trying to implement an optimization routine in R (Newton Rhapson). I have some R functions that calculate the gradient and hessian (pre requisite matrices) fairly efficiently. Now, I have to call this function iteratively until some convergance criterion is reached. I think the

ANN is written in C++; my C++ is very weak. Last year I didn't experience any problems with

It looks as though the problem isn't in R - I provoked a SIGSEGV under R 1.1.1 on RH62: > for (i in 1:100) an1 <- ann(cbind(runif(1000), runif(1000)), k = 4) > for (i in 1:100) an1 <- ann(cbind(runif(1001), runif(1001)), k = 4) Program received signal SIGSEGV, Segmentation fault. 0x40111109 in chunk_free (ar_ptr=0x401a5d40, p=0x8849a30) at malloc.c:3111 3111 malloc.c: No such

Hi, I am writing a for loop that creates one object, say 'outn' on every round of the loop. I would like the name of each object to include the index of the loop as in, for example: out1, out2, out3, ... And I would like the naming of the object to take place automatically as the loop moves through? Similarly, I would like to be able to call different objects (in1, in2, in3,

Hi, there: I am wondering if there is a quick way to "reverse" a list like this: t0 <- list(a=1, b=1, c=2, d=1) reverst t0 to t1 > t1 $`1` [1] "a" "b" "d" $`2` [1] "c" thanks. -- Weiwei Shi, Ph.D Research Scientist GeneGO, Inc.

I"m getting build errors I think from one of your patches O tjoml. You need to have a build area that builds with clang and does warnings as errors to avoid these issues on putback. here is my configure step for example: /home/rkotler/llvm_trunk/configure --enable-werror --prefix=/home/rkotler/ll vm/install CC=/home/rkotler/llvm_3_2/install/bin/clang CXX=/home/rkotler/llvm_3_

I'm still seeing this problem.
