[R] How does Sweave write to a file?
Hello.
I need that Sweave writes R output to a file. To do it, I put the following
into the foo.Rnw file:
\documentclass{article}
\usepackage{Sweave}
\begin{document}
...
echo=F=
x - rnorm(100)
y - rnorm(100)
sink(foo.txt)
summary(lm(y~x))
sink()
@
...
\end{document}
When I run:
R CMD Sweave foo.Rnw
R responses:
Warning message:
In sink() : no sink to remove,
and It doesn't work. Somebody knows how I can fix it?
Thanks,
Arnau.

[R] compute the associate vector of distances between leaves in a binary non-rooted tree
Hello. I'd like to compute the associate vector of distances between leaves in a binary non-rooted tree. The definition of a distance between two leaves in a binary non-rooted tree is the number of edges in the path joining the two leaves. I've tried the ape package but I'm unable to find this vector. For example, using rtree(5,rooted=F) I've obtained the following tree: $edge [,1] [,2] [1,]67 [2,]71 [3,]78 [4,]82 [5,]83 [6,]64 [7,]65 $tip.label [1] t4 t3 t2 t1 t5 $edge.length [1] 0.9126727 0.2765674 0.4996832 0.7904400 0.8508797 0.8174133 0.9027958 $Nnode [1] 3 My question is: how to compute the vector of distances between the 5 leaves. This vector is in this case: v=(d(t1,t2),d(t1,t3),d(t1,t4),d(t1,t5),d(t2,t3),d(t2,t4),d(t2,t5),d(t3,t4),d(t3,t5),d(t4,t5))=(4,4,3,2,2,3,4,3,4,3). Thanks in advance, Arnau. Arnau Mir Torres Edifici A.

[R] duncan test in R
Hello. Sorry if the question I'm asking is trivial but I'm unable to find the answer. How can I make a duncan test of multiple rank in R? That is, the designed test to see which mean levels are different in an one factor ANOVA. Thanks in advance, Arnau. Arnau Mir Torres Edifici A. Turmeda Campus UIB Ctra.

[R] Sweave and accents
Hello. I want to write my notes in Sweave in my own language (spanish). But my language has accents and when I run Sweave in R to translate my Snw file into the tex file the accents are translated into unrecognizable characters. For example, the word camión (truck) is translated into camión Somebody knows how can I do it? One solution I don't like is using a perl program to substitute my accented letters into normal accents in LaTeX in my Snw file before running Sweave. That is: á - \'a é - \'e ... The problem is when I run the spelling program, it doesn't work because the spelling doesn't recognize the words with normal accents. There is a solution but it is tedious: 1) substitute the accented letters letter into normal accents in LaTeX. 2) run Sweave and create the tex file. 3) subtitute the normal accents into the accented letters in the tex file. My question is: Is there another way to do it? Arnau. Arnau Mir Torres Edifici A. Turmeda Campus UIB Ctra.

For example, I want to generate n=100 random vectors of two dimensions for a normal with mean c(0,1) and variance matrix: matrix(c(2,1,1,3),2,2).
