how to rename rows/columns of a matrix?
Hi I get a matrix with the columns named like "X13 X22 X1 X14 ...", i.e. not successively. That has it's good reasons, but now how can I rename the columns to "X1 X2 X3 ..."? Thanks a lot, David

rbind question
Hi I am trying to replicate a vector in n rows for comparison purposes with another matrix. foo <- c(1,2,3) bar <- rbind(foo,foo) # does the trick for 2 rows bar <- rbind(rep(foo,2)) # does something else How do I generate a matrix with all rows=foo without writing 'foo' n times as arg? Thanks, David

RE: document.getElementsByClassName (prototype) andElement.childrenWithClassName (scriptaculous) redundancy?
Isn''t the difference that the scriptaculous one only gets child nodes from the node you specify, whereas the prototype one gets all in the entire document? Still, it would be nice to just have the one, and let you pass in the document element if you wanted all of them. Just guessing, really. I haven''t looked at the code in question.

Dendrogram labels
Is there any way to change the orientation of the labels on the end of the dendrograms to horizontal rather than vertical? If so, how can I do that. _____________________________________________ Patrick Richardson Biostatistician - Program of Translational Medicine Van Andel Research Institute - Webb Lab 333 Bostwick Avenue NE Grand Rapids, MI 49503 ph. 616.234.5787 This email message,

use of split lines in ess
Hi all I am very astonished that R generates a "syntax error" when I want to split up a line with a backslash, which usually works in any shell script. R itself generates the "+" symbols at the beginning of following lines in a splitted line so I've tried with them as well, but also without success. Searching in the h-help archive did not reveal any answer either.

matrix manipulations
Hi cor(x,apply(x,1,sum)) gives me the correlations of each column with the sums of each row (correct me if I'm wrong, please). What I need are the correlations of each column with the sums of each row except the entry in the given column. It seems that for any one column i I get it by doing: cor(x[,i],apply(x[,-i],1,sum)) But I struggle to get it for all the columns. I was trying things

unclear alias behaviour
Hi all In /etc/aliases I have set up an alias for "root" pointing to "david" which is a unix account. Other email accounts are virtual dovecot accounts, one of them is "andel". They all work fine using /etc/postfix/virtual when used with the domain name which is defined in /etc/postfix/virtual.domains. But the alias "david andel" in /etc/postfix/virtual

how to divide a string into characters? - for comparing strings that is
Hi I am searching for a way to do something like "ABC" -> c("A","B","C"). How can this be accomplished? I tried cut() and split(), but they do something else, it seems. The purpose for doing this is to find the number of common (and uncommon) characters, i.e. ultimately I want something like this: > foo("ABD","ADE") c(2,1) # 2

character -> list
Hi I have a matrix of type "character" (strangly) and am trying to apply the function "aggregate" to it, but unfortunately without success. It seems to me that aggregate would work, if I only could get rid of the quotation marks around each item. So for a very simple example which looks as my actual data look (of course here I put the quotation marks on purpose, but I have

How to generate a pairwise non-parametric comparison table?
Dear list I am comparing the results of several different experimental setups. With kruskal.test() I can test if there is any difference at all in any of them, if I understand it correctly. But now, when there is a difference, how do I generate a (half-) table of pairwise comparisons, using e.g. wilcox.test(), to find the ones where the difference actually occurs. I guess I don't have to

Legend Position
List, Is there any way to specify the position of the legend from within the following code? If so, how can I do it. As it stands it in the bottom left corner and I want to move it to the top right. I'm not sure if I can use the default "plot" or if I need to go with the lattice package. Suggestions much appreciated. plot(y, xlab="Survival Time (Months)",

Validating a Cox model on an external set
Good morning, Sorry to trouble the list. I have a problem I hope to seek your advice on. Essentially, I am trying to 'validate' a multivariate Cox proportional hazards model built in a training set, by testing it on an external test set. I have performed a survfit using the Cox model to predict survival for the test set, and obtained individual predictions for survival time, with
