similar to: Introduction to mark-recapture analysis in R?

Hi all, I have just started using RMark to analyse capture-recapture data. I am trying to analyse a simulated data set using the Robust Design (two primary periods with three secondary sessions in each) to estimate apparent survival. On specifying the time intervals (that tell R about the primary and secondary sampling sessions), this is the error I get: > time.int <- c(0,0,1,0,0) >

Hello, please excuse the simplicity of this question as I am not very good with stats. I am taking a class, using R which I am learning at the same time, and the questions asks us to "Estimate the average abundance using Poisson regression with a log link". I can estimate the abundance from "x", but I can seem to figure out how to get the average abundance in this method. Any

Hello, I am almost new in R, so perhaps my question will be silly. I try to use R for analyzing capture-recapture data in epidemiology. A cancer registry has different sources of patients. We know in each list, patients already known in all other list. The aim is to use capture-recapture models for estimating the number of patients unknow of all the sources. Because no order in sources, one

Hello everyone, R beginner, I am confronted with the need to use Rmpf. In my first scripts I made use of X=read.table(file.choose(), header=FALSE, sep=",",dec=".") X=as.matrix(X) to load into a matrix data from file before matrix use. How can I do to load the same data in a "mpfrMatrix". Is it possible to use with "mpfrMatrix" the same as operations

I am trying to load a package called Rmark, but when I run library(Rmark) I get the following: > library(RMark) Error in !character.only : invalid argument type Error in library(RMark) : .First.lib failed for 'RMark' When I try to load Rmark from the packages menu, I get: > local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg)) library(pkg,

Hi all, I am working with a capture-recapture analyses and my data set consists of a typical set of encounter histories. Thus, for each individual I have a string (same length for all the individuals) consisting of 0 (not seen) and other numbers (seen in state "1", seen in state "2", etc. where state may refer to breeding, nesting, feeding, etc.). At the end of each string I

Dear All, I learned about R during my studies at Cologne University of Applied Science. Now I work at Allianz Dresdner Bauspar AG and I would like to install R here too. Is there any license issues that need to be taken in consideration, any fees to pay by the company? I know there are answers to this in the FAQs but I didn't really understand the legal language. Could you therefore just give

Dear all, how can I plot a line graph and a bar graph in one single figure? I tried to combine "barplot" and "plot". Even though they both have the same x-values (1 to 55),  it just doesnt look as if they match in their scale (the barplot is much wider than the "plot"....even though I tried to put limits on the x-axis). Here is an example of what I did:

Dear R-helpers, I would like to do a Spearman rank order test, and used the cor() function with the method "spearman". It gives me a number (correlation coefficient?) , but how can I get the p-value? Thank you for the help in advance! Regards, Anne-Katrin -- [[alternative HTML version deleted]]

Dear All, I have data in HDF file format and would like to read it into R. I have tried the package hdf5 without success. Any ideas and suggestions??

Dear Madams and Sirs, because the DOI foundation recommends a new, secure resolver [1], I wanted to suggest the attached patch. It a) updates a static DOI link in the docu, b) the code chunks that generate new ones, and c) a reg-ex that detects DOI links. Hopefully, my first venture into SVN & patch files was done correctly. My apologies, if there is anything amiss. In that case, I'll

Hello, I would like to label outliers (or all dots) in a plot plot(as.matrix(ValAddInd_byYear), as.matrix(Cons_Elec_Ind_byYear)) ideally by the 30 different row.names, but anything else (x or y values, for example) would already be helpful. I've tried various things with pch, but they didn't work and I can't find anything else. Any hint appreciated! Thanks, Katrin

Dear All, I fear that this is a really easy question but I do seem to go around in circles.. I have 2 points on a plot and would like to calculate the slope of the line drawn through these 2 points. that cant be so hard?!

Dear List, How do I pick the p-value out of the urppTest result? For adfTest the p-value can be extracted by A2 at test$p.value following A2 <- adfTest(myData[,i], lags=2, type=c("c")) What do I do for urppTest? The above doesn't seem to work. There is a slot @test with $output, which is a list of various test results that didn't want to give away only the p-value

Dear R Help-Team, If I start R and type in search() the result is: [1] ".GlobalEnv" "package:ctest" "Autoloads" "package:base" I often need an Add-on-package. I can load it with "> library(package)" or include a require-command in the .First-function. The .First-function is fine, if I always use the same working directory. But I

Hallo, I'm using the R Version 2.3.0 (2006-04-24) on Suse Linux 10.1. With an older R and Linux version I could write a R-function into a file and execute it with the command: R --vanilla < script.r In the file script.r was code like this: postscript(file="results.eps") x<-2 y<-3 plot(x,y) dev.off() It worked fine, but now nothing happens.
