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, 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 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 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, I have a question related to the correct interpretation of the relative convergence criterion used by 'optim'. In the help of the function is it written that: "reltol:Relative convergence tolerance. The algorithm stops if it is unable to reduce the value by a factor of reltol * (abs(val) + reltol) at a step." and I was wondering if the previous criterion is

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, 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, 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 R and hydrological/environmental community, A major release of hydroPSO is now available on CRAN. This new release: -) implements the Standard Particle Swarm 2011 (SPSO-2011) -) is parallel-capable, to alleviate the computational burden of complex models with "long" execution time -) has an improved performance (33% - 38% faster) -) allows normalization, when the parameter space

Hi, Does anybody know how to have output from print, without the leading [1]? (Or must I use cat/write?) >out="r15" >print(out,quote=FALSE) [1] r15 And I definitely do not want the leading [1] as I want to construct a table from this.
