hello, I'd like know how to sort a data frame in R for example how I should do to sort by Catholic with swiss data frame like below thanks Fertility Agriculture Examination Education Catholic Infant.Mortality Courtelary 80.2 17.0 15 12 9.96 22.2 Delemont 83.1 45.1 6 9 84.84 22.2

Hi, I just installed Ubuntu 12.04.4. I installed R by following instructions from CRAN after modification into my /etc/apt/sources.list file sudo apt-get update sudo apt-get install r-base sudo apt-get install r-base-dev When I try to load library(gdata) ou library(gplots), I have error message : library(gdata) gdata: read.xls support for 'XLS' (Excel 97-2004) files

Hi, I recently discovered the R program and I thought it could be useful to me. I have to analyse data saved as .Px file (x between 0 and 8 - .P0 files have 18 lines at the beginning that I have to skip). New files are generated everyday. This is my strategy : In order to analyse the data, I first want to copy the new data in a database in MySQL (which already contains the previous data). So

Having a problem running the ace command in ape. After reading my table into R and then putting the names of the rows in the table in same order as the tree I can't get ace to run and get the message Erreur dans as.matrix(x) : dims [produit 25] ne correspond pas ? la longueur de l'objet [0] This is the command I am using and each of the vectors used in the snalysis.

Dear all I would like to superpose some smoothing line through boxplot in ggplot > dput(ad) structure(list(konc.f = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 6L, 6L, 6L, 7L, 7L, 7L, 7L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 6L, 6L, 6L, 7L, 7L, 7L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L,

Dear R-help members Since this morning (5/2/2025), I get an error when I try to load optimx package. I solve it and I send my solution but if someone has a better idea or understand what's happened, I will be most happy to know. MacOSX 15.3 R 4.4.2 nlopt installed using brew install nlopt Here are the steps to produce the error and a solution to solve it. Some parts are in French. I

Hi, everyone, I am just trying to use Rcpp in my computer, and I would like to try a simple example from website, but R keeps reporting me error. I am using Windows XP, and has installed Rtools and GSI. Here is the response: > src = ' + Rcpp::NumericVector xa(a); + Rcpp::NumericVector xb(b); + int n_xa = xa.size(); + int n_xb = xb.size(); + + Rcpp::NumericVector xab(n_xa + n_xb - 1);

Hello everyone, First of all, I apologize for my poor English. I am a beginner with Wine and I am already astonished by the possibilities given by such a software. In fact, I got a VB application that I want to use under my Ubuntu Dapper Distrib. This application is based on the creation of some objects as : - scripting.filesystem - scripting.dictionary - msxml2.serverXMLHTTP -

Hi, That looks like the dependency on nlopt for nloptr (used by several of the solvers) was somehow missing. There is SUPPOSED to be a check of what is installed and a warning issued, but possibly one got missed. Even some base packages do sometimes need the external libraries manually installed, and I find I'm doing that after various OS updates or resets when the long term support runs out.

Have you tried using tools:::package_native_routine_registration_skeleton()? If you don't like its output, you can easily edit its results and still avoid most pitfalls.

Hi All, I am using RHEL 6.4 on a Dell Server with 32 cores. But in the Cpus_allowed_list only 30 cores are available. Why is that? See the snippet from cat /proc/self/status: Cpus_allowed: 7fff7fff Cpus_allowed_list: 0-14,16-30 The allowed list is same for the init process as well (see below). I didn't see this issue, in RHEL 6.2. Why is that? Is there a way to change it? -miraj

I am a newbie Ruby and RoR user. In my tests using the turorials that I found over the web, everthing is working fine and I am very impressed about RoR framework. As I am a Delphi developer, without any web development experience, There is some thing hard to understando and I didn''t find a tutorial about this. I wonder how to create a non-scaffold page ? I have customers,

Dear list, I'd like to use multiple imputations to try and save a somewhat badly mangled dataset (lousy data collection, worse than lousy monitoring, you know that drill... especially when I am consulted for the first time about one year *after* data collection). My dataset has 231 observations of 53 variables, of which only a very few has no missing data. Most variables have 5-10% of

Hello Everyone,   This is my first attempt to do something in R. As a precursor to a Willingness to Pay analysis, I want to conduct a Mixed Conditional Logit analysis but am unsure how to proceed because of some nesting within my data.   Below is some data and code that illustrate what I’m trying to do. The data are based on responses to a conjoint survey obtained during pilot testing. In the

I'd like to have a data.frame structured something like the following: d <- data.frame ( x=list( c(1,2), c(5,2), c(9,1) ), y=c( 1, -1, -1) ) The reason is this: 'd' is the training data for a machine learning algorithm. d$x is the independent data, and d$y is the dependent data. In general my machine learning code will work where each element of d$x is a vector of one or

Hi Bryan and other klibc people. I have taken a stamp on the Makefiles for klibc, this is what I came up with. 1) No longer recompile on every invocation 2) Correct checking on dependencies 3) Simpler makefile syntax (almost all over the place) I compile-time tested it only. Two open issues: a) Do we realy use .a files for initramfs. I renemed that to the executable. b) I renamed

I'm getting constantly high numbers of page reclaims & involuntary context switches for dovecot/auth. page reclaims = minor faults = cpu switching back to system-mode, But why is the auth process doing that so excessively? Same for the large number of involuntary context switches... Attached is my "dovecot -n" output. Date: Sun, 07 Nov 2010 20:40:34 +0100 type real

I am having a series of problems using date time data that has been converted into a POSIXt and POSIXlt classes. I have hourly time series data from 1900 that has been converted from text data. I assume most of my problems come from a mis-underdanding of the POSIX class. My matrix named (aa) for this year is approx 8700 by 4. When I try to calculate the length of posit column ( which is the

In the past 2 months another change occurred in the CVS code that broke my ssh-keyscan patch. Here's an updated version that tweaks the changed name (in the Kex struct) and also causes an attempt to grab an ssh2 key from an older server (without ssh2 support) to fail earlier and without an error message (Stuart Pearlman emailed me some code for this). This patch is based on the BSD CVS
