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, 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.

Mirando los comentarios, realmente lo que deseo es encontrar la raíz real de (-0.5)^(1/5) la cual debería ser -0.87055056329. José me hace caer en cuenta que además de no encontrar la raiz real, tampoco da todas las raiz complejas. Habría alguna manera de que tuviera en cuenta? > ------------------------------ > > Message: 6 > Date: Thu, 15 Oct 2015 11:25:39 +0200 > From: José

Hola a tod en s. Realizando el calculo de encontrar la raíz quinta de -0.5, la cual dígito de la siguiente manera (-0.5)^(1/5) El resultado que me arroja R es NaN. Averiguando un poco entre las ayuda de las funciones aritméticas encuentro el siguiente comentario Users are sometimes surprised by the value returned, for example why (-8)^(1/3) is NaN. For double inputs, R makes use of IEC 60559

El problema del módulo es que pierde el signo. En tu caso sale igual porque has invertido el signo del coeficiente en el polinomio (en realidad se me pasó a a mí advertir que el término independiente debe ir con signo negativo): .> polyroot(z=c(0.5,0,0,0,0,1)) [1] 0.7042902+0.5116968i -0.2690149+0.8279428i -0.2690149-0.8279428i [4] 0.7042902-0.5116968i -0.8705506+0.0000000i .> .>

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, 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 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 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, 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, 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

Estimados usurios-R: Tengo una lista de alumnos. Hay alguna forma de sacar una tabla de frecuencias por la asistencia a clases mensual. Es decir cuantos días concurrió cada alumno en el mes. Supongamos que la lista está conformada por ocho alumnos, el curso duró 4 días y quiero saber cuantos días concurrió cada uno al curso poniendolo en la columna mes. Quisiera obtener un cuadro así: Alumnos

Dear list, I need to change a value within a particular line of a plain text file with characters and numbers, and I haven't found any way of doing this by using R. What I have a is a file that doesn't have tabular data (so, I think that 'read.table' or 'read.delim' are not the right tools for this), but some text, and I now exactly the row that has to be modified and the
