HI there, I have been trying to use a code posted on R help to be able to calculate area under the curve for complicated data points and there seems to be an issue with the code: no "b" object found. I am not a good R user and can''t find were the problem is. Any help? Thanks!! This is the code ( as a test run I gave it this info because I know the answer: x<-seq(1:50)

Hi there: I am a total beginner in R, and I have a simple question: I have a table with thousands of lines that represent locations, and two columns: latitude and longitude. I need to randomly sample 1000 lines. How do I do it? I know the command "sample", but it samples elements independently, not lines. If there is a better place for me to ask that type of question, please let me

Hi, everybody. Sorry to bring up the subject again but I have visited the revolution computing web page, but its not clear when or what will be the new release be. Does anybody have information about that?. Does anybody know if the version that will be released will be validated?. I have been reading the previous mails about validation and I work in a Pharma company and validation is a big

Hi all, there is a vector v with several NAs. I want to create a new vector n of the same length as v and the same NAs as in v and tried this: n <- vector(length=length(v), mode="numeric") replace(n, which(is.na(v)), NA) but this does't work, all values in n are 0. What went wrong? Thanks, Sven -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Hi Paul: I am from Brazil and was looking for help to solve a memory problem using R. I found your answer to Melinda on https://stat.ethz.ch/pipermail/r-devel/2003-July/027094.html. You say there that you are not familiar with what to do when using Windows. I'm using Windows and would like to know if Melinda found a way to solve her problem. Can you give me her e-mail address?? Thanks...

Tengo un archivo de texto donde cada línea es de la siguiente forma: "aa-mm-dd hh:mm:ss Nombre Apellido" ¿Hay alguna forma de usar read.table o algo similar para obtener directamente un data frame que tenga dos columnas donde una tenga la fecha y quede de tipo PosiX y la otra character con el nombre completo? Gracias, Sebastián.

Dear all, I don't understand the following behaviour: Running compar.gee (in library ape ) with and without the option 'data', it give me different results Example: ....

Hi, I'm attempting a comparative analysis using the function compare.gee, package (ape), which uses phylogeny as a correlation matrix in gee (package gee), in R version 2.2.0 on a Windows XP PC. I'm looking to model the relationship between a continuous explanatory variable and a binary response variable for 600 species, taking into account the phylogeny of those species. Here's

Hello, I am trying to run the APE program COMPAR.GEE with a model containing a categorical response variable and a mixture of continuous and categorical independent variables. The model runs when I have categorical (binary) response and two continuous independent variables (VAR1 and VAR2), but when I include a categorical (binary) independent variable (VAR3), I receive the following output with

Hi guys: Sorry if this question is very basic. I?m learning basic matrix and vectors multiplication to develop a population matrix model for plants. I?m trying to multiply the elements of two vectors (each of the ?x? values by each of the ?y? values) to obtain a square matrix of xy values. f.e. x<-seq(5,205) y<-seq(5,20,5) stages<-c(?Sdl?, ?Juv?, ?Ad1?, ?Ad2?) If I just multiply xy as

Estoy escribiendo una función en R para análisis de modelos lineales y tengo problemas al ejecutarla porque dicha función usa otra función, también creada por mi, y cuando ejecuto al primera me dice que no encuentra la segunda. Ambas funciones están guardadas en la carpeta work y al entrar al programa siempre cambio el directorio a work. No sé cual es el problema, si está mal el search-path o es

Hello, Much like Charlie Wills a year ago, I am trying to run the APE program COMPAR.GEE with a model containing a categorical response variable and a continuous variable.

I was trying to learn cross building an R pcakage for windows on my linux machine. I picked a relatively small library gee to test.

I've been comparing variables among objects (taxa) related by known trees, using phylogentically independent contrasts in the ape package, and want to move on to more complex models e.g. by using gls with appropriate correlation terms. My trees contain lots of (hard) polytomies and information about ancestors, which I've been including- creating fully dichotomous trees by using zero branch

Hi, I am fitting a GEE model using gee R package, but I am not sure how to get OR and its CI? Could anyone give me some hints?
