similar to: bugfix for nls with port algorithm (PR#13540)

Hi, I got this error every time when I put upper and lower bound on my parameters in nls. I'm not quite sure what this error is about. I also wanted to find the content of nls_port_fit. But typing this directly into R doesn't seem to give any result out. I also tried to see the content of If anybody could shed some light I'd greatly appreciate. Thank you. rc

Hello r helpers! Below is the whole coding for my programme. Before proceed more further, let me explain for you. First of all, I need to compute trimmed mean. Till that step is ok. Then I need to compute ssdw which is sum of square deviation. If I do equal trimming at both tail of distribution that I chose, I will use the first ssd formulae which is "a". But if I am doing unequal

I realise the it's hard to do a seek in a variable bitrate file but I didn't think it was this bad. It seems to vary a lot with the file but the total time to do an ov_open() and ov_pcm_seek() can add upp to a second or more. By this time my DirectX buffers have wrapped around and are looping. Can anybody think of a solution for this? I really need a faster response time for my in-game

Hi Im using the newest GetText gem, and Im having problems with classes outside rails, they don''t get translated. For example: I have a class representing access in my app, and it is not a ActiveRecord, just a normal class. When require ''gettext'' and include it in the class, I can use the _('''') methods fine. They get picked upp by rake updatepo.

Hi everyone: I am just wondering how can I use weights with MCMClogit function (in MCMCpack package). For example, in case of glm function as given below, there is weights option in the arguments. Aparently there is no option of using weights in MCMClogit. glm(formula, family = gaussian, data, weights, subset, na.action, start = NULL, etastart, mustart, offset, control =

The documentation for nls says the following about the starting values: start: a named list or named numeric vector of starting estimates. Since R 2.4.0, when 'start' is missing, a very cheap guess for 'start' is tried (if 'algorithm != "plinear"'). It may be a good idea to document that when algorithm = "port", if start is a named

Ive been googling quite a bit now for problems with running out of mbuf clusters. Im basically sending a 30k datachunk down 1000-4000 connections, but 1000 is more than enough to quickly fill upp 8192 mbuf clusters. I also tried setting maximum amount of mbuf clusters to 65536, but that only made the box hard-wire 86MB of 96MB RAM, making it just as unsuable as a dead machine. Of course, when the

Hello, I'm tring to install a Rpackage that holds some C//C++ code as far as I understood the R library generic compilation mechanism, compilation of C//C++ sources is controled 1) at system level by the ocntentos RHOME/etc/Makeconf 2) at user level by the content of ~/.R/Makevars 3) at package level by the content of src/Makevars Problem I have is that src/Makevars is ignored see

Dear R-helpers, does anyone know of some package/function that can build a network from the functions that are implemented in a package, i.e. visualize the cross-references from one function to another in the same or some dependent package? An example would be a function like 'nls' on top of the hierarchy and then a network of nodes from the functions that are called within 'nls'

Dear stats experts: Me and my little brain must be missing something regarding bootstrapping. I understand how to get a 95%CI and how to hypothesis test using bootstrapping (e.g., reject or not the null). However, I'd also like to get a p-value from it, and to me this seems simple, but it seems no-one does what I would like to do to get a p-value, which suggests I'm not understanding

In testing pqR on Solaris SPARC systems, I have found two bugs that are also present in recent R Core versions. You can see the bugs and fixes at the following URLs: https://github.com/radfordneal/pqR/commit/739a4960a4d8f3a3b20cfc311518369576689f37 https://github.com/radfordneal/pqR/commit/339b7286c7b43dcc6b00e51515772f1d7dce7858 The first bug, in nls, is most likely to occur on a 64-bit

Hola: Probablemente está tomando 'Edad_Manova_18a54' y 'Genero2_1a2' como variables numéricas (integer). Deberías convertirlas en factor. Por ejemplo: Edad_Manova_18a54 <- factor(Edad_Manova_18a54) Genero2_1a2 <- factor(Genero2_1a2) Manova.fnc(datosPAS, variables=2:6, fac.inter=c('Edad_Manova_18a54','Genero2_1a2'),poshoc=c('todos')) Saludos,

Muy buenas, He usado muy poco R en mi vida, y ahora estoy intentando hacer una MANOVA, con dos variables independientes (Edad, que tiene 4 niveles y Genero que tiene 2) y 5 variables independientes. Le he puesto también que me haga el poshoc de las dos y la interacción. Decir también que me instalé el ULLRToolbox, que no se si tendrá algo que ver con el error que me da. Este es el código que uso

Hi, I have been using the function lme() of the package nlme to model grouped data that is auto-correlated in time and in space (the data was collected on different days via a moving monitor). I am aware that I can use the correlation classes corCAR1 and corExp (among other options) to model the temporal and spatial components of the auto-correlation. However, as far as I can tell, I can only
