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

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, 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 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, 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, 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, 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 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

Hiya everyone. I have been working on a fun little app to watch what's going on in your asterisk box via its manager interface. There's a screenshot up and some info at http://sitkavoip.com/astsee/ -- Sorry it requires allegro, but I was more keen about getting the ideas down than worrying about the framework. Comments/questions welcome, but probably off-list is best unless they

The 'cacher' package contains a set of routines for caching statistical analyses. The idea is that an analysis stored in a file (say, 'foo.R') is run and the results of the evaluated expressions are cached in a database. These cached results can subsequently be packaged up and distributed over the interweb. I've just uploaded to CRAN version 0.1-2 of the 'cacher'
