writing statistical function for boot
Hi everyone, I need help in writing a statistical function for bootstrap. Suppose m is a matrix with n cols and p rows, my original data. What I want to do is a bootstrap (using boot from package boot) on eigenvectors from a PCA done on m with a statistic function calculating the eigenvector bootstrap error ratio. If R = number of bootstrap replicates, then my function should look something

Installation issue R 2.6.1
I am seeing a peculiar installation problem with the R installation files for Windows: R2.6.1 fails to install on MS-Vista with a file corruption issue. But, the same R2.6.1 exe does install OK on Windows ME. The same problem exists with R2.3.1: Fails to install on Windows Vista Succeeds install on Windows ME Succeeds install on Windows 2000 and Windows 98 so it cannot be the installation

garch function in tseries package
I am wondering how to run 'garch' function of 'tseries' package in R2.6.1. I installed R2.3.1 and R2.6.1 in my PC (Windows XP Home) and run a following simple GARCH function in both versions: >garch(dSP[1:300], order = c(1,1)) where 'dSP' is daily return series of a stock index. R2.6.1 can not finish calculation and also I can not stop the

Florida mirror (cran.hostingzero.net) dead?
The CRAN host in Tampa, FL (cran.hostingzero.net) isn't responding, and hasn't responded in quite a while -- at least problems were reported more than a year ago (Oct 2007) http://finzi.psych.upenn.edu/R/Rhelp02a/archive/116706.html although someone apparently succeeded in July 2008 http://finzi.psych.upenn.edu/R/Rhelp02a/archive/137451.html Perhaps it's just flaky, and not

- round() strange behaviour
Hi, I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even .... For example: > round(1.5)[1] 2> round(2.5)[1] 2 While i would expect that round(2.5) be 3 and not 2. Do you have any explanation for that? I really appreciate your input, Monica

spliting strings ...
Hi everyone, I have a vector of strings, each string made up by different number of words. I want to get a new vector which has only the first word of each string in the first vector. I came up with this: str <- c('aaa bbb', 'cc', 'd eee aa', 'mmm o n') str1 <- rep(1, length(str)) for (i in 1:length(str)) { str1[i] <- strsplit(str, "

Spatial join – optimizing code
Hi, Few days ago I have asked about spatial join on the minimum distance between 2 sets of points with coordinates and attributes in 2 different data frames. Simon Knapp sent code to do it when calculating distance on a sphere using lat, long coordinates and I've change his code to use Euclidian distances since my data had UTM coordinates. Typically one data frame has around 30 000 points

Pros and Cons of R
Hi, I am doing a very informal presentation for my office about R capabilities to deal with and analyze spatial data, display data and maps, and connections with GIS. I've used in my presentation info from the CRAN, the spatial Task view, and the more striking graphics examples from http://addictedtor.free.fr/graphiques/thumbs.php and NCEAS

Hi everyone, ? I am trying to get a point of intersection between a polyline and a straight line ?.. and get the x and y coordinates of this point. For exemplification consider this: ? ? set.seed(123) ? k1 <-rnorm(100, mean=1.77, sd=3.33) ?k1 <- sort(k1) q1 <- rnorm(100, mean=2.37, sd=0.74) q1 <- sort(q1, decreasing = TRUE) plot(k1, q1, xlim <- c((min(k1)-5),

Installing Rgraphviz package on a windows vista pc
Hi, I want to install Rgraphviz on a windows vista pc. The only source file that I found in the bioconductor homepage is a tar file. I can't install from this using the packages command in the R menu. I would like to get some tips on how I can do the installation. Can I just place the extracted Rgraph folder (from the source tar file) in the library folder of R2.6.1 along with the other

a more elegant way to get percentages?
Hi, I am trying to get percentages in a more elegant way. I have a data.frame with locations and values (counts) of species at that location. Each location is repeated for each species i have values for and i would like to get percentages of each species at that location. I am not sure if i am clear in my explanations so i will paste my code below: ##################### > x locat val 1

Correspondence and detrended correspondence analysis
Hi, I hope someone knows the answer to this or has a real good reference about it (I am using Legendre & Legendre, Numerical Ecology, 1998).... My data is a data.frame with locations as rows and vegetation assemblages / species as columns. I've done a PCA, a correspondance analysis (CA) using ca in ca package and a detrended correspondance analysis (DCA) using decorana from vegan package.

Installation of packages via GUI, Mac OS X
All, I'm running R v2.7.1 on Mac OS X. When I go to the R package installer GUI, I am not prompted to select a repository. The usual screen is there but the columns for package, installed version, and repository version are all populated via blank entries. If I select "Get List" the error below occurs. The same thing occurs if I go form the command line via install.packages.
