Dear list members, Within a loop, I need to create an xyplot with only a legend, not even with the default external box drawn by lattice. I already managed to remove the axis labels and tick marks, but I couldn't find in the documentation of xyplot how to remove the external box. I would really appreciate any help with this ------------- START ----------- library(lattice) x<-1:100

Dear list, For the maintainer of a given package, is it possible to change the licence of a it from GPL >= 2 to GPL >= 3 ?

Dear List, Recently I got the comment that the implementation of the random number generator used by default in R (Mersenne-Twister) could not be "safe" for 64-bits machines, so I decided to put the question here because I do not have expertise in that topic, and because this question could be "too technical for R-help's audience". I apologise if this is not the case.

Dear list, For the implementation of a particular optimization algorithm it is very important the random number generator. I would like to know if somebody could tell me what is the random number generator used by default in the 'runif' function. >From the help page of 'runif' and '.Random.seed' I guess that the default algorithm is 'Mersenne-Twister', but I

Dear List, While trying to define a customised CITATION file for a package, following R-exts, I realised that if I use only one 'citEntry' I got both a text description and a BibTex entry for the package, as for the 'nlme' package: -------------------------- citation('nlme') To cite package 'nlme' in publications use: Jose Pinheiro, Douglas Bates, Saikat

Dear List, I'm building a package that uses 2 functions of the 'sp' package, and I declared them in my NAMESPACE file as follow: importFrom("sp", proj4string, coordinates) The package is built without any problem, but when I load the package, I get the following message: " Loading required package: sp Note: polygon geometry computations in maptools

Dear R developers, Taking advantage of the yesterday discussion about the use of Depends/Import/Suggests/Enhances, I would like to add a related question. Let's assume, in the DESCRIPTION file of my package foo0, I have: Depends: foo1 Imports: foo2 while in the NAMESPACE file of my package I have importFrom("foo2", f2) and within my package I use the following two external

Dear R developers, Due to the increasing use R in hydrology and other close-related environmental sciences, I would like to ask if it would be possible to create a new Special Interest Group mailing list, called 'R-sig-hydro', specially devoted those topics. If possible to do so, I'd offer myself to maintain such mailing list (if needed). Thanks in advance, Mauricio

Dear List, While using the --as-cran option for checking one of my packages: R CMD check --as-cran hydroGOF_0.3-3.tar.gz I got the following error message: pkgname <- "hydroGOF" > source(file.path(R.home("share"), "R", "examples-header.R")) > options(warn = 1) > library('hydroGOF') Error in loadNamespace(i[[1L]], c(lib.loc,

Dear list, This is my first time trying to set up the development version of R (R-devel ) in my local machine to test some packages before submitting them to CRAN. I'm using Linux Mint 17.1 64-bit, which is an Ubuntu-based distro. However, I'm not able to correctly set up r-devel, apparently due to a problem with enabling the shared library support. I run the first script given by Dirk

Hi, I'm trying to get a toy program making use of nmmin to run successfully. I've gotten to the point of compiling. However, when I attempt to run my executable, I guess a bus error. I see that someone else has asked about using nmmin before <http://tolstoy.newcastle.edu.au/R/help/06/03/23944.html>, but I haven't come across any replies. Is there some documentation on how to

Hello to all, I have been using an optim with the following call: optim(param_ini,fun_errores2,Precio_mercado=Precio,anos_pagosE2=anos_pagos,control=list(maxit=10000,reltol=1e-16)) depending on the intial values I'm getting the same solution but once I get the convergence message=10 (no convergence) and for the others I get convergence message = 0 Solution1: $par beta1

Hi, I apologize for the long message but the problem I encountered can't be stated in a few lines. I am having some problems with the function constrOptim. My goal is to maximize the likelihood of product of K multinomials, each with four catagories under linear constraints on the parameter values. I have found that the function does not work for many data configurations. #The likelihood

Hello, I get a segfault when running glmmboot in my own package glmmML. Has happened many time before, but this time I get no hint of where in my C functions the error might be. I give the output below. Can this be an R bug? I suspect it has to do with repeated calls to 'vmmin' like this: for (...){ vmax = vmaxget(); vmmin(*p, b, &Fmin, bfun,

I am trying to use the R API to call optim functions (nmmin, vmmin, lbfgsb, etc.) through a C program but I couldn't find the shared library to link under the R-2.6.0 build which is compiled under Linux (REL5). main.cpp:35: undefined reference to `Rf_initEmbeddedR(int, char**)' main.cpp:41: undefined reference to `nmmin' Thanks in advance for any help. ------------------------
