Hi, I have a NN model build using AMORE and NNET.If i want to reuse the model built on later date.How can i store this model.In what format should i need to store the model.I wont be saving the session.I want to just store the model and recall this model whenever required.Is it possible to store? If yes,can someone provide any packages available. Regards, Raghav [[alternative HTML version

Hi all I’m in desperate need of help. I’m working with a grouped data object, called Orthodont in the nlme package in R, and am trying to fit various models (learning methods for my thesis), but one of the variables in the object is numeric, (age) and I need it to be a factor. I’ve tried: as.factor(Orthodont$age) as.factor(as.character(Orthodont$age)) and various other things, but when I then

Folks, I have a very basic question. The solution eludes me perhaps because of my own lack of creativity. I am not attaching a fully reproducible session because the issue may well be becuase of the way the data file is, and the data file is large (and I don't know whether I can legally distribute it). If people can suggest things that might be wrong in my data or the way that I am reading it,

Hi, this post is about foreach operators, the compiler package and the last update of doMC that includes support for the compiler functionality. I am using a home-made %dopar%-like operator that adds some custom expression to be executed before the foreach loop expression itself (see sample code below). It used to work perfectly with doMC 1.2.1, but with the introduction of the compiler

Hi, suppose you have two versions of the same algorithm: one in pure R, the other one in C/C++ called via .Call(). Assuming there is no bug in the implementations (i.e. they both do the same thing), is there any well known reason why the C/C++ implementation could return numerical results non identical to the one obtained from the pure R code? (e.g. could it be rounding errors? please

Hi, I am facing with a strange behaviour of isClass and extends when these are called in .onLoad in both R 2.12.1 and R 2.13.0. This is preventing my package from doing some object initializations at a proper place (i.e. in .onLoad). Suppose one defines two S4 classes in a package, and that one needs to check the inheritance between these two when loading the package (e.g. to validate slots

Dear All I'm attempting to speed up my model building procedure, but need some help with the loops I've created...please bear with me through the explanation! My basic model call is something like: m0sulf.nlme<-nlme(conc~beta0*exp(-beta1*day)+beta2*exp(-beta3*day), data=m0sulf, fixed=(beta0+beta1+beta2+beta3~1),

Hi folks, R on ESS Why it is unable to pop up help manual on "R on ESS"? ?layout Error in help("layout", htmlhelp = FALSE) : unused argument(s) (htmlhelp = FALS ?plot Error in help("plot", htmlhelp = FALSE) : unused argument(s) (htmlhelp = FALSE) etc. But they work on R console and popup the manual without problem.

Hi, is there a reason why when calling the argument 'lib.loc' of library() is not used when trying to load the required packages? 0. Package A depends on package B 1. Install packages A and B in a subdirectory 'lib' of the current directory 2. Call: library(A, lib.loc='./lib') This will give something like the following: Loading required package: B Error: package

Hi all Just this morning I upgraded to R 2.12.0 (for Mac OS X 10.6.4). All went well until I needed to run a help() or help.search() in my session, which I'm running within Emacs (ESS 5.3.7). Say I need help with the command 'density'. When I type help(density) or ?density the ESS help buffer opens, it is titled *help[R](density)* but it contains only a couple of lines saying,

Hi I am trying to install the package "pheno", but it needs the package "nprq" by Roger Koenker et al. which I can I find this package?

hello all i searched the archives and couldn't get a solution to the following question. i have the following function: F=function(z,v) { if (v==-.5) return(1) else return(2*v/z + 1/Recall(z,v-1)) } and while testing whether it works (ie F(z,v) is approx = besselK(z,1+v)/besselK(z,V). the recursion formula allows one to calculate besselK(z,1+v)/besselK(z,V) for large values of z )

Hi, in R 2.12.1, R CMD check hangs when building a vignette that uses a foreach loop with the doMC parallel backend. This does not happen in R 2.13.1, nor if I use doSEQ instead of doMC. All versions of multicore, doMC and foreach are the same on both my R installations. Has anybody encountered a similar issue? Thank you.
