Hi I have the feeling, that the argument stringsAsFactors has no impact in the function expand.grid: a <- c("PR", "NC", "A2", "BS") b <- c(1, 0.5, 0.25, 0.125, 0.0625, 0.03125) class(expand.grid(css, fscs, stringsAsFactors=FALSE)[[1]]) [1] "factor" class(expand.grid(css, fscs, stringsAsFactors=TRUE)[[1]]) [1] "factor" Also, when

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, 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

Dear R community, I'm running R 32 bits in a 64-bits machine (with 16Gb of Ram) using a PAE kernel, as you can see here: $ uname -a Linux mymachine 2.6.18-238.el5PAE #1 SMP Sun Dec 19 14:42:44 EST 2010 i686 i686 i386 GNU/Linux When I try to create a large matrix ( Q.obs <- matrix(NA, nrow=6940, ncol=9000) ), I got the following error: > Error: cannot allocate vector of size 238.3

Hi all I have problems in accessing a mer object called model.01 from a workspace that was created with R 2.8.1 and saved with save into an .RData file (on Windows XP or Ubuntu 8.10, don't remember anymore). Now I want to open it in R 2.9.0 on Ubuntu 8.10. I use # load workspace load("name.RData") which seems to work: ls() # all objects in there [1] "all"

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

Hello again :) I''m trying to run rcov on my specs here but i''m getting a lot of segmentation faults (and they usually happen at different places): /home/mauricio/NetBeansProjects/reeds/vendor/rails/activerecord/lib/active_record/attribute_methods.rb:211: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i486-linux]

A small number of columns in the data I need to work with are strings, the rest numbers. I'm using read_excel() from the readxl package to get the data ; right after it, the string columns are of type chr and the rest num. I'm tasked with finding out which columns are integers. From an advice, I tried saving the spreadsheet content into a CSV then loading that, which works like a charm ;

In the help page for ?is.integer, there is this function is.wholenumber <- function(x, tol = .Machine$double.eps^0.5) abs(x - round(x)) < tol A quick question: is there a case where this alternative function will not work? function(x) x %% 1 == 0 Best, Adrian -- Adrian Dusa University of Bucharest Romanian Social Data Archive Soseaua Panduri nr.90 050663 Bucharest sector 5

Dear R experts, we are preparing an R-package to compute the Oja Median which contains some C++ code in which random numbers are needed. To generate the random numbers we use the following Mersenne-Twister implementation: // MersenneTwister.h // Mersenne Twister random number generator -- a C++ class MTRand // Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus // Richard J.
