No matter how I´ve tried o find a solution for this simple question, I can´t. Sorry for bothering with such a matter. I have an excel-files with some empty cells=missing values. How do I tell R that these should be NA´s? > TRFLP1 <-(read.table(file="S://SEDIM//Kokeilu//TRFLP1.txt",col.names= c("Dye_Sample Peak", "Sample_File_Name", "Size",

Hi all. I would be very pleased if someone could help me, as I do not seem to get the different branches of my tree painted in different colours. The closest I get is colouring the names of my samples(=names of the branches). Here is the code. data <- read.table(file = "S://SEDIM//TRFLP//B12.5_50-700bp.txt" , as.is = TRUE, header = TRUE, sep = "\t", row.names =

Dear, I am trying to visualise a time-progressing line (it's supposed to represent spread patterns) using brew package and Google Earth. The idea is to have a function which takes start and end point geographic coordinates, as well as number of intervals to chop the path up, and returns the collection of points segmenting this line. Unfortunately my calculations fail for large distances,

Hello list, I have some serious problems on my ext3 filesystem. Several folders contain files, which cannot be accessed in any way, not even a stat() on these files is possible: [~]$ ls -l -rwxrwxr-x 1 yvonne users 30208 2007-09-16 12:49 Stoffverteilungsplan tw kl4 07.doc ?--------- ? ? ? ? ?

Attached is patch to provide support for OpenSpace in mapstraction. A demo can be seen at http://yvonnesplants.co.uk/openspace_demo.html. Note that OpenSpace seems sometimes to have a problem with links clicked from email. If you get an error ''HTTP referrer not valid'' then open a new browser window and paste in the link and it should be ok. The following features are not

I've been using the nlme library to construct lme models and I'd like to extract an r-sq value for the model - how do I do this? With glm I just used the reported (null deviance-deviance)/(null deviance). Deviance is not reported directly for lme nor can it be extracted using the deviance() function. How do I work out the deviance or can I work out R-sq in some other way? Thanks, Yvonne

Mich besch?ftig folgende Fragestellung. Ich kenne die Verteilung (lognormal) zus?tzlich weiss ich das 99%, das 90% und das 1% Quantil. Gibt es in R eine M?glichkeit die Lognormalverteilung zu finden, das heisst den korrespondierenden logmean und logsd? Vielen Dank f?r ihre Hilfe Gruss Yvonne

Hi, I have a problem with making PCA plots that are readable. I would like to set different sympols instead of the numbers of my samples or their names, that I get plotted (xlabs). How is this possible? With points, i don´t seem to get the right data plotted onto the PCA plot, as I do not quite understand from where it is taken. I dont know how to plot the correct columns of the prcomp

I have two problems running Samba on Solaris 2.51, Samba version 1.9.16p11. 1) When browsing the CADCAM group, which is where the Sun group is, the CADCAM name shows up on Explorer, but when I click on the group to browse the contents, the '+' disapears and the group apears to be empty. We can, however, map drives using \\sun01\sharname' directly. 2) When we dial into the network

It is a trivial problem, but in the book I couln`t figure out how to put different colours at different regression lines plot(bif,abund,type="n", xlab= "number_bifurcations", ylab="abundances") sbif<-split(bif,stage) sabund<-split(abund,stage) points(sabund[[2]],sbif[[2]],pch=16, col="red") for(i in 1:2) abline(lm(sabund[[i]]~sbif[[i]])) Thanks in

Dear all, I am using the hclust method in R. I am building nice dendrograms with it. Actually for my further analysis I want to get the number of bifurcations (bif) for each object (labels) in the dendrogram. That has to be calculated by the colums merge, height and order. http://www.nabble.com/file/p16142989/Sc2Mown_Pred.txt Sc2Mown_Pred.txt Sc2Mpred<-

I have been using lme to model data with multiple nested random effects and continuous response variables however I also have data with a binary response variable, binomial errors and multiple levels of nesting of random effects (e.g. site/block/quadrat/year), is there a package available which will do this? Jim Lindsey's package "repeated" appears to be only able to cope with 2

Dear helpers, I tried these models to run in the package nlme, but allways got the same error message... I have a correlation in 5 sessions within a field (n=12) with ten traps in one field. res2a <- lme(response~x+y+z+treatment),correlation = corARMA(form = ~ session|trapfield, p = 1, q = 0), random=~1|field, na.action=na.omit, data=plates, method="ML") res2a <-

Hallo I have the following problem 1) Problem: I am unable to read data in the xls-format in the PerformAnalytics package. While it works well for several commands, e.g. t(table.Stats(msci_ret)) it does not work for other commands, e.g. x <- msci_ret[, c("CH"), drop = FALSE] table.Drawdowns(x) The error code is: Error in checkData(R) : The data cannot be converted into a

Hello everyone! I have a little problem: HRH = trusted domain (Samba 3) Hendricks = trusting domain (NT4 sp6a) Trusts are setup between the NT4 and Samba3 + OpenLDAP domain and appear to be working properly. When logged into the HRH domain on a W2k workstation I can view,read, and write on available shares for HRH groups and users on our Windows file servers. Whenever I try to see available

Dear R helpers, I am quite new working with R, and that might be a very easy question for some of you. So I hope you can help me!! I used a hirarchical cluster analysis to create dendrograms, like that: hc <- hclust(dist(USArrests), "ave") plot(hc) plot(hc, hang = -1) Here I want to compare the number of bifurcations for each species, but therefor I need this numbers first. There

Dear posters, I have a question concerning binary data analysis. I have presence absence data of 5 sampling sessions within 3 years, of 12 fields. Each field had 12 traps. I would like to analyse the data with a Generalized Estimating Equations (GEE) Model in R. For the abundance data I used a gls with the function: correlation = corARMA(form = ~ session|trapfield, p = 1, q = 0) But now I want

Hi I am interested in extending mapstraction to include the UK Ordnance Survey OpenSpace API (http://openspace.ordnancesurvey.co.uk). First can I check that no-one else is working on this? Assuming not, is there any documentation that might point me in the right direction to get started, or should I just search the code for case ''google'' and insert appropriate code at each
