hello, We've got a problem with the mix package in order to impute the missing data. After importing the data, the prelim function does not work (only the stlouis data works). We have done : >library(mix) >Manq <- read.table("C:/.../file.txt") >attach(Manq) >save(Manq,file="C:/../R/rw2001/library/mix/data/Manq.rda") >data(Manq) >Manq V1 V2 V3 V4 1

Hi all, I am just beginning to use R and encountered a problem in trying to draw a regression line using the command "abline(coef(var)" and similar ones but got the error "plot.new has not been called yet". Does anybody know how can I call plot.new? Is this an additional package to be found somewhere on the web? Is it a functionality that I just have to "activate"

Dear R users, I have to include typical UNIX formated R commands and outputs into the article using LaTeX. What is the easiest way to include R prompt commands and text outputs (including messages) into LaTeX documents? Is there any template or library? So far I'm trying to produce R commands in LaTeX using LaTeX general format options. Thanks, Rado

R-help, Long ago I asked how to sort a data frame according to one of the columns. But Iwas wondering ho I could "double sort" , i.e, sort according to one column and another one afterwards. It is quite easy in Excel but I am unable to implemented in R. I have searched in the R help archives and found nothing. Thank you in advance.

Hi I want to extract a row from a data.frame but I want that object to be a vector . After trying some different ways I end up always with a data.frame or with the wrong vector. Any pointers? x <- data.frame(a = factor(c('a',2,'b')), b = c(4,5,6)) I want to get "a" "4" I tried: as.vector(x[1,]) a b 1 a 4 (resulting in a data.frame even after in my

Dear list, If anyone knows how to assign dimnames to matrices or arrays I would be most grateful for help. I've tried various permutations of likely-looking code but get error messages every time. I could find no example in the documentation. Many thanks, Dan Bebber Department of Plant Sciences University of Oxford South Parks Road Oxford OX1 3RB UK Tel. 01865 275000

Firstly hi to everyone on the list, I am new to this list ans also R so please forgive the simplicity of my questions over the next few months. I have version R 1.9.1 and want to perform z-scoring for a benchmarking procedure. I have tried to install Henrik Bengtsson's R.classes bundle (http://www.maths.lth.se/help/R/R.classes). I have downloaded the .zip file and placed the relevant folders

I have columns in two tables that need to be compared in order to get a statistic. The function calculating the statistic is somers2. Here are the two columns I must calculate, row by row. name1 name2 1 Pred_pres_a_indpdt[,3,,] population[,23] 2 Pred_pres_b_indpdt[,3,,] population[,24] 3 Pred_pres_c_indpdt[,3,,] population[,25] 4 Pred_pres_d_indpdt[,3,,]

HI! I'm using the function dev.copy2eps to store a plot into a file. How can I change the default name of the file and the path where the file should be created ?

Sorry I have a very simple question: I used somers2 function from Design package: > z<- somers2(x,y, weights=w) results are: >z C Dxy n Missing 0.88 0.76 500 0.00 Now I want to call only the value of C to be used in further analyses, but I fail to do it. I have tried: > z$C NULL > z[,C] Error in z[,C]: incorrect number of dimensions and some other silly

Dear R-ers, somehow it is not possible to increase nsize to more than 20000k. When I specify e.g. > R --vsize=10M --nsize=21000K the result is: free total (Mb) Ncells 99658 350000 6.7 Vcells 1219173 1310720 10.0 Maybe I have overlooked s.th....

Hi, I know it must be written somewhere but I can't find it. I'd like to remove all variables or objects that I've created but not the functions. I look at a few things without success. Is there a R way of doing this? There are to many to create a manual list. Thanks in advance. Yves Gauvreau -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

This code works: x<-letters[1:6] ycols<-23:28 xcols<-rep(c(3,4,5,8),each=length(ycols)) somertime<-function(i,j)somers2(Pred_pres_a_indpdt[,i,,], population[,j]) results<-mapply(somertime,xcols,ycols) How can I make variable "h" work? x<-letters[1:6] ycols<-23:28 xcols<-rep(c(3,4,5,8),each=length(ycols))

I am trying to create a set of vectors which have similar names. They have a common part and an extra unique part. I am sure I have seen questions on this before but I have been unable to find it in the archive. There are examples of sets of names for columns of a data frame, but not for individual vectors. Suppose I want vectors named myvar.1 myvar.2 etc. I tried: >

Hi all, I'm a potential new user of R and have to know this before I start using it: SPSS does not let you do a Post Hoc analysis on repeated measures data. This is a problem for me, since that is what I will have to do. Will R let me do this? /Fredrik -- ----------------------------------------------------------------- Fredrik Karlsson, Research Student Department of Philosophy and

Dear People, I have been trying to perform concatenation operations on lists without success. Consider the following example. > x <- runif(2) > y <- runif(2) > z <- runif(2) > xy <- list(x,y) > xyz <- list(x,y,z) I want to have a function foo such that foo(xy,z) is the same as xyz. This appears not to be as easy as I thought, though there must be a way. For example

Is there a quick way to make boxplots groups by two variables? By that I mean, that if x axes have values ("A","B","C"), than at each value there would be a few boxplots each for a value of second variable (say ("1","2","3")).

In Matlab or Octave I can evaluate (evalf) the content of a string. In R I have looked around in the docs, but have not found a way to do something equivalent (which is possible, I think). Can anybody give me a pointer? ============================================================================= Thomas Hoffmann, Institut fuer Halbleiter- und Mikrosystemtechnik, TU Dresden E-mail: hoffmann at

plot(rnorm(100000),type="l") plots only about 7e4 lines while the same without type="l" works fine. Is this a feature or a bug or is this configurable?
