Thanks. This should be resolved in R-devel(r72788) and R-patched (r72789) Best, luke On Mon, 12 Jun 2017, Berend Hasselman wrote: > > > In this email to the R-help list: https://stat.ethz.ch/pipermail/r-help/2017-June/447474.html > and in this question on Stackoverflow: https://stackoverflow.com/questions/44486643/nleqslv-memory-use-in-r > > Andrew Leach has raised a question

Hello all, I am relatively new to R, but enjoying it very much. I am hoping that someone on this list can help me with an issue I am having. I am having issues with iterations over nleqslv, in that the solver does not appear to clean up memory used in previous iterations. I believe I've isolated the/my issue in a small sample of code: library(nleqslv) cons_ext_test <- function(x){

Dear R-users, I use the "nleqslv" function to get parameter estimates by solving a system of non-linear equations. But I also need standard error for each of estimates. I checked the nleqslv manual but it didn't mention about SE. Is there any way to get the SE for each estimate? Thank you very much. [[alternative HTML version deleted]]

Dear all, I initially ran into this problem while rebuilding a package dependent on nleqslv. I got the following error: Error in match.arg(global) : 'arg' must be of length 1 This didn't occur in previous versions of nleqslv, but did in the current one (2.4). I think I pinned the problem down to the following example: Take two functions: test <-

I'm solving 4 complex equations simultaneously. Code is below. The code returns only zero's for the solution though there should also be a non-zero result. I'm pretty confident that the equations are correct because they are straight from a published paper and I checked them pretty thoroughly. The parameter values I used are from the published paper as well. Any suggestions for how

Dear all, I am relatively new to R and have had some difficulty in understanding an error i get when running a code to solve a system of non-linear equations, with four equations and two variables. This is my code: ALPHA <- c(-0.0985168033402, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4) BETA <- c(-0.0985168033402, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4) GAMMA <- c(0.3940672148378, 0.1, 0.15,

Hi, Is this method broken in R? I am using it to find roots of the following function: f(x) = 2.5*exp(-0.5*(2*0.045 - x)) + 2.5*exp(-0.045) + 2.5*exp(-1.5*x) - 100 It is giving an answer of -38.4762403 which is not even close (f(x) = 2.903809e+25 for x=-38.4762403). The answer should be around 0.01-0.1. This function should converge.. Even for a simple function like f(x) = exp(-x) * x, it gives

Santi, In the second line of your function you have the following: f <- numeric(length(x)) This sets the length of this numeric vector (i.e., "f") to the length of the vector "x". Later, inside the function you assign to values to 4 elements of the vector "f". This assumes that "f" is at least 4 element in length. However, you define

A commenter on SO suggested that I copy my question to R-devel http://stackoverflow.com/q/31972325/850781 I have had --8<---------------cut here---------------start------------->8--- library(compiler) compiler::enableJIT(3) --8<---------------cut here---------------end--------------->8--- in ~/.Rprofile for years; now that I upgraded to 3.2.1 I get this on startup:

Hi all, I'm trying to do some object-oriented programming in R using the R.oo package. Right from the start I encountered a strange (at least for me) problem. I define a new class/constructor based on the R.oo documentation. However the first attempt to create an object fails: === Code: === library(R.oo); setConstructorS3("MyClass",function(param) { print(param);

Hello, Due to exploration of the JIT capabilities offered through the {compiler} package, I came by the fact that using enableJIT(2) can *slow* the rpart function (from the {rpart} package) by a magnitude of about 10 times. Here is an example code to run: library(rpart) require(compiler) enableJIT(0) # just making sure that JIT is off # We could also use enableJIT(1) and it would be fine fo

I'm not sure if this is a bug or expected behavior, but I don't see anything in the documentation that explains it, so I thought I'd mention it: ~ michaelweylandt$ R -q --vanilla library(compiler) enableJIT(3) `+` # Throws an error `+` # Throws a warning `+` # Prints the primitive as expected sessionInfo() R version 2.14.1 (2011-12-22) Platform: i386-apple-darwin9.8.0/i386

You want to look at the apt-add-repository command, basically you provide that command like: * sudo add-apt-repository 'deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.8 main' * sudo apt-get update * sudo apt-get install clang-3.8 Cheers, -Neil.

And let's also spell things properly! Like 'internationalisation' ...'Weasels have got into your phone system' instead of 'gotten into your phone system...' And 'please press the hash key..' instead of 'pound key' There should probably be en_uk, en_us, en_ca, en_za, en_nz, en_oz, en_ie and en_in etc to allow each English-speaking country to localise
