Hi, I am trying to solve a model that consists of rather stiff ODEs in R. I use the package ODEsolve (lsoda) to solve these ODEs. To speed up the integration, the jacobian is also specified. Basically, the model is a one-dimensional advection-diffusion problem, and thus the jacobian is a tridiagonal matrix. The size of this jacobian is 100*100. In the original package

Hi, I'm trying to analyse some time series data on dissolved organic nitrogen. Because it has gaps in it, I try to interpolate (linear) with the regul method from the pastecs package. I have a number of stations with measurement series in a matrix constructed from a data frame with the unstack method (temp) I also used the unstack method to make a similar matrix for the time points

Hi everybody, I have a list, where every element of this list is a data frame. An example: Mylist<-list(A=data.frame, B=data.frame, C=data.frame, D=data.frame) I want to rbind some elements of this list. As an example: Output<-list(AB=data.frame, CD=data.frame) Where AB=rbind(A,B) CD=rbind(C,D) I’ve tried: f<-function(x){ for (i in

Hi, I would like to plot the following equation: dF(x)/dx=(k1+k2F(x))(1-F(x)) where k1 and k2 are parameters that I have estimated already. How can I plot the curve in R? Thanks! Montserrat Rue Universitat de Lleida (Spain) [[alternative HTML version deleted]]

Hi All, Just about to set up RoR on our server and was wondering what the ideal setup for RoR is these days? Apache 1? Apache 2? fCgi? Any guidance would be helpful! Thanks, -Adam

I have data from several sensors that recorded data at hourly intervals during seven months. I want to separate daily variation from the trend, and also be able to zoom in on only one month of data. I have not been able what functions to use, I can not figure out from the help for 'ts' how to use hourly data. I guess this is routine-work for a lot of people so I hope someone can

Hola compañeros de la lista, qué tal. Estoy haciendo un análisis de componentes principales utilizando las funciones "dudi.pca" (paquete "ade4") y "PCA" (paquete "FactoMineR"). Sucede que al comparar las coordenadas de cada individuo que obtiene cada función, las que corresponden al segundo componente principal tienen idéntica magnitud pero con

Hi, I''m newbie to rails, so please be gentle with me. I got one of the new powerbooks that apple just released last month (october 2005). I installed rails using RubyGems and also the installer for mac osx found here http://www.tonyarnold.com/articles/2005/08/10/rolling-with-ruby-on-rails-on-mac-os-x-tiger-for-beginners everything seems to update and install fine. But when I type

Hi, I'm new to CentOS and also on the list, since I usually work with Debian. My problem is as follows: I have a NAS where users connect to do their backups. Each user has a folder shared where only he can enter. Multiple users get connected from a CentOS 5.7 to the NAS, each in its shared folder. I connect to the NAS by entering the login, password and shared folder of user A (here I

This is a generic request concerning were to look for finding appropriate information on a precise procedure in R. I’m using R for teaching introductory statistics and my students are learning how to deal with it. However, I find it difficult to locate some of the procedures. For instance, for basic crosstabulation, it is obvious that basic functions as table, ftable, and prop.table can be used.

I really like to use R for all my graphs, and as I work with stable isotopes I want to have a proper chemical notation in my plots I have looked at ?plotmath, but didn't find the answer and also searched the R website. ------------------------------------------------------------------------ -- plot(1:10,xlab=expression(^{14}*C)) # I want to have a superscript with nothing in front, but it

I want to create a character vector based on the table (shortened for display) below: Where there are ones in the matrix I want the column name to appear and where there are zeros nothing, which would make the vector in this shortened case: combinations <- ("A B","A C","A E H","A F G","B C D","E G H",A C D E H","A C D F

Hello useRs, I have some problems when I try to plot a lattice. The lattice has 200 columns (X value) and 5 rows (Y value), with a total of 1000 squares. I want to plot this lattice with the squares having different colours according to a variable value. The variable I want to plot is cover value of a shrub, and it has values between 0 and 1. I want to plot the squares with value 1,

I have been using R for a few months to plot my data, and fit statistical models and so on. It is stated that R is not only a package for statistcs and graphics but also a programming language. Currently I am working with Fortran 90 to do numerical simulations (1D reactive -transport), and subsequently visualize it in some external software (spreadsheet). As I now started using R I will plot my

Hello fellow R people, I can not figure out a pretty way to use strplit with vectors Imagine that I got the following data from someone with ID's representing several factors ID data A1-B1-t1 0 A1-B1-t2 1 A1-B2-t1 5 A1-B2-t2 10 A1-B10-t1 0 A1-B10-t2 1 A1-B20-t1 5 A1-B20-t2 10 ... I would like to turn this dataframe to station substation time data A1 B1 t1 0 A1 B1 t2 1 A1 B2 t1 5

Dear R-gurus, I would like to zoom in a plot, e.g. I select a region on the x-axis and then I would like the ranges on the y-axis to change accordingly. Is it possible to do this with existing functions, or do I have to invent some data selection before plotting? See below a short example, where I select ylim with trial and error, which I want to avoid. Cheers, Henrik Andersson

Hola Jesús, Muchas gracias por tu respuesta. Te comento algunas dudas iniciales que tengo respecto a la versión gratuïta de RStudio Server Open Source. * Características técnicas del servidor: Consulté hace unos días el enlace que has pasado (https://www.rstudio.com/products/rstudio/download-server/), donde se apunta que Rstudio Server puede instalarse en plataformas Linux. Según indican

I have an issue using mle in versions of 32 bits. I am writing a package which I want to submit to the CRAN. When doing the check, there is an example that has an error running in the 32 bits version. The problem comes from the mle function, using it with a lower constrain. In 64 bits version it works fine but when I put it in the R 32 bits it fails. (same numbers, all equal!) The call is:
