Hi, Using R 2.15.1 on Windows 7. Have installed both versions 32 and 64bit. In both of them among others I have installed a package rgenoud When I open R gui of 32bit and write library(rgenoud) it responds by showing a functional rgenoud version 5.7-8. The same it does on Rgui 64bit. Now I am working in cygwin (v. 1.12.4.0) with xwin. Normally before when I had installed a package, I only had

I am trying to get contents of a REST response: getURL("http://localhost/myweb-app/rest-ws") This is a web application (myweb-app) which is providing a REST web service (rest-ws)... Unfortunately, the HTTP status sent back is 404. If I request the url using Chrome/IE, I get a HTTP status 200 OK. In Opera the request does not succeed either. I am using 2.15.1 (Win7, 64Bit) and just

My R version: 2.15.1- windows While creating an R package in windows, i want to include an image (a .gif image) that will finally be in the package. A function in my package will call the gif image. Where should i put the images before running "Rcmd build mypkg" or "Rcmd INSTALL --build mypkg", so that after creating the package, the .zip file / .tar.gz/ .tgz would have the

I was trying to convert a vector of POSIXct into a list of POSIXct, However, I had a problem that I wanted to share with you. Works fine with, say, numeric: > v = c(1, 2, 3) > v [1] 1 2 3 > str(v) ?num [1:3] 1 2 3 > l = as.vector(v, mode="list") > l [[1]] [1] 1 [[2]] [1] 2 [[3]] [1] 3 > str(l) List of 3 ?$ : num 1 ?$ : num 2 ?$ : num 3 If you try it with POSIXct,

Are they the same with .RData being the newer format?? Thanks, ...Tao

Hi, I'm trying to user lmer function from lmerTest package because, if I understood correectly, it allows to make better inference than lmer method from lme4 package. However, whatever I do I keep getting this error: Error in lme4::lFormula(formula = mark ~ ssCount + sTime+ : rank of X = 1660 < ncol(X) = 1895 any ideas what could be a problem? thanks, Srecko [[alternative HTML

Hi, I am using 32-bit R v 2.15.1, on Mac OsX v 10.6.8 with R GUI 1.52 Leopard build 32-bit (6188). I have also replicated this error on R 2.13.2 on a windows 7 machine. In some sequences of numbers, I am unable to use the which() function to index certain values. It seems to be primarily numbers with a 3 in the decimal. For example: > S=seq(0,4,0.01) > which(S==2.02) [1] 203 >

Dear all, I have an R script that uses Rcpp, and I have been trying to parallelize it using mclapply (I tried with the multicore and the parallel library) Sometimes (not always, interestingly), the CPU use for each core drops, usually so that the total over all cores reaches 100%, i.e., as fast as if using just one single core fully. I tried my code directly from within emacs, and also using a

Hello r-help, I've been banging my head against the computer in an attempt to learn how to divide my matrix into segments by rows. I want to be able to return each segment as a newly named object. I've tried looking at the apply functions and creating a for loop but brain no work. Here's the basic starting objects that I believe would be needed to separate the matrix. mat <-

Dear R users, I am running simulations (1000), and in my simulation I am looking at specific sums. For example, if the sum is >=4 then count this, if say <3, then don't count, if the sum=3, then generate a random number from uniform distribution, if this number is say less than 0.5, then count this sum, if greater than 0.5, then don't count. I am having trouble with introducing this

Hi all: My OS is 32bit winxp,but I wanna install 64bit R2.14.1. >From the following website,it says "You can also go back and add 64-bit components to a 32-bit install, or vice versa" http://cran.r-project.org/bin/windows/rw-FAQ.html#Can-both-32_002d-and-64_002dbit-R-be-installed-on-the-same-machine_003f Does it mean that I can install and run 64bit R2.14.1 under 32bit

Hello everyone, I'm having a big trouble with which seems to be a bug in as.POSIXct() date-time conversion. I have massive GPS datasets in which each location has it's own date and time attribute. As I convert them to POSIXct format, 1300 cases (of about half a million locations) simply return NA values. I picked up a small sample of failed cases and normal cases to demonstrate the

Hi all:I found some great demonstrations of interactive presentation graphics generated in R with the SVGAnnotation package, here:http://www.omegahat.org/SVGAnnotation/http://www.omegahat.org/SVGAnnotation/SVGAnnotationPaper/SVGAnnotationPaper.htmlI tried to install the package available at that website (it's not on CRAN) and am getting some pretty uninformative errors (see below).

Hi, I used to use reshape and moved to reshape2 (R 2.15.1). Now I tried some of my older scripts and was surprised that my cast function wasn't working like before. What I did/want to do: 1) Melt a dataframe based on a vector specifying column names as measure.vars. Thats working so far: dfm <- melt(df, measure.vars=n, variable_name = "species", na.rm = FALSE) 2) Recast the

Hi, I am trying to normalize some data. First I fitted a principal curve (using the LCPM package), but now I would like to apply a transformation so that the curve becomes a "straight diagonal line" on the plot. The data used to fit the curve would then be normalized by applying the same transformation to it. A simple solution could be to apply translations only (e.g., as done after a
