Comparing two matrices
hi:
I have matrix with dimensions(200 X 20,000). I have
another file, a tab-delim file where first column
variables are row names and second column variables
are column names.
For instance:
> tmat
Apple Orange Mango Grape Star
A 0 0 0 0 0
O 0 0 0 0 0
M 0 0 0 0 0
G 0 0 0 0 0
S 0 0 0 0 0

Reading many files at once
dear group,
i have 100 files starting with 'hsa-*'.
ex. file:
fruit p-value
------------
apple 0.0003
orange 0.004
kiwi 0.0003
peach 0.0004
I want to read all these files and create a single
matrix. here each file may have different fruit names.
in the matrix i want to have a union of all fruits and
those should be the rows in the matrix and file names
should be columns.

Arrange elements on a matrix according to rowSums + short 'apply' Q
Greetings,
My goal is to create a Markov transition matrix (probability of moving from
one state to another) with the 'highest traffic' portion of the matrix
occupying the top-left section. Consider the following sample:
inputData <- c(
c(5, 3, 1, 6, 7),
c(9, 7, 3, 10, 11),
c(1, 2, 3, 4, 5),
c(2, 4, 6, 8, 10),
c(9, 5, 2, 1, 1)
)

persp(): add second plane (second, long question)
Thank you for your replies so far.
Sorry for bothering you again, but I'm still not able to get what I need as
I don't understand all parts of the replies (just using R for easy
things....).
Is there a code for plane3d() like some of you sent me for points3d()? I was
not able to get that out of the scatterplot3d package...
What I can do is to get the x,y and z-range for the xlim,ylim and

pairwise combinatons of variables
Dear WizaRds,
although this might be a trivial question to the community, I was unable to
find anything solving my problem in the help files on CRAN. Please help.
Suppose I have 4 variables and want to use all possible combinations:
1,2
1,3
1,4
2,3
2,4
3,4
for a further kmeans partitioning.
I tried permutations() of package e1071, but this is not what I need. Thank you

Using pipe for input data
Hi.
I have asked this question before and Aaron J. Mackey and Tony Plate gave me

to accomplish. So let me ask again...
What I am trying to do is to make R read data from pipe (stdin).
Say I have following files on my directory

model.frame deficiency
The model.frame function has trouble with a certain type of really long
formula. Here is a test:

tmat <- matrix(rnorm(500), ncol=50, dimnames=list(NULL, tname))
tdata <- data.frame(tmat)
temp1 <- paste( paste(tname, tname, sep='='), collapse=', ')
temp2 <- paste("~1 + cbind(", temp1, ")")

Contributors on R-Forge
Hi,
I've recently taken over maintenance for the "xtable" package, and have
set it up on R-Forge. At the moment I'm pondering what the best way is
to handle submitted patches. Basically, is it better to:
1) Be non-restrictive regarding committer status, let individuals
change the code with minimal pre-commit review, and figure changes can
be reviewed before
