boxplot of different colors
Hello,
I am making a boxplot of 13 boxes.
I tried to color the box using 13 colors but failed.
Only red and brown were displayed.
Green, blue, and grey disappeared.
Please kindly advise modification after checking the code below.
Thank you in advance.

S4 method selection based on second argument
I'm translating some Matlab code and need some help figuring
out how to change this call into an S4 generic method.
In matlab, there's a function called 'repmat' with three
calling sequences (all I have to deal with anyway):
1) B = repmat(A, m, n)
2) B = repmat(A, [m n])
3) B = repmat(A, n)
In all cases, A is the fill value, m is number of rows,
and n is number of

Creating a Sparse Matrix from a Sparse Vector
Hello,
I am working with a sparse matrix that is approx. 13,900 by 14,100. My
goal is to select a row out of the matrix and create a new matrix with that
row repeated 13,900 times without having to do any looping. Example:
Starting Matrix:
exampleMatrix
3 x 4 sparse Matrix of class "dgCMatrix"
[1,] 1 . . .
[2,] . 1 . 0.5
[3,] . . 1 ..
New Matrix:..

Analog to matlab repmat function
Hello,
I'm trying to switch from Matlab to R-project, and having some difficulties.
I make a use of multidimensional matrices. For example, I need to extract
mean from one of the dimensions:
% we have matrix data of size: 130 x 11 x 350 x 2
data = data - repmat(mean(data,3),[130 1 1 1]);
In R project I managed to do that in a very pervarsive way:

Graphical representation of a matrix ?
Hi,
The function Repmat under S allows to represent a matrix of data.
Is there an equivalent function under R ?

Rsyncing Problem with - character!
Dear Rsync Users,
Please can I have a bit of rsync advice?
I am trying to rsync a file called.
'Draft text - with Holley comments.doc' from machine a to machine b.
Unfortunately this isn't working because I think rsync recognises the -
character and thinks it's an option.
I have tried escaping this out as well as putting it all in " " but

Help with Matrix package
Hello all,
A colleague at work set me the challenge to convert some MATLAB
code into R, to see which is faster. We'd seen that benchmark comparing
MATLAB 6.5 to R1.90 (and others), and so I thought that I should be able
to get roughly comparable speeds. The code has lots of multiplications
of matrixes, transposes, and MATLAB's "repmat". I did the code
conversion, and R was about

Non-linear optimisation
Hi there,
I have a piece of Matlab code I use to optimise a trding strategy. If there
are any Matlab/R specialists out there, I would appreciate your help in
doing the exact same optimisation in R.
I suspect I would use nlm() in R but am not sure where to define my
constraints.
I have attached my Matlab code below for reference.
Many thanks.

sparklines in lattice
Dear R-help,
Has anyone implemented sparklines in the strips of a lattice plot? What I have in mind is, say, highlighting that part of a time series that one is examining in more detail in a set of lattice plots.

array manipulation
Hello,
I'm at the very beginning of the learning process of this language.
Sorry in advance for the (possible but plausible) stupidity of my question.
I would like to find a way to permute the DIMENSIONS of an array.
Something that sounds like the function "permute()" in matlab.
Given an array C of dimensions c x d x T , for instance, the command
permute(C, [2 1 3])

ordering a data frame to same order as a chr vector
Hi all,
I've got a data frame that has an identical column to a chr vector. I would
like to use the chr vector to order the rows of the data frame to be
identical to the order in the chr vector (the contents of the chr vector are
completely identical to one col of the data frame), but this is proving
trickier than it sounds..
Any help would be much obliged,

Ellipsis arguments for plot.formula
Hi:
I have a function as follows:
my.plot <- function( x, y = NULL, ... )
{

Set up the variables:
x <- 1:10; y <- x; tdf <- data.frame( x, y ); main.str <- "test"
I will exercise the function in two ways:
> my.plot( y ~ x, tdf, main = "test" )
This works fine
