The plotting order in lattice is determined by the levels of md$idno. By

One solution is to cut() 'x' according to the breaks defined by 'y'.
Using cut with labels=FALSE is really fast. See a simulation below.
However the accuracy depends on the number of ties you have in your

Perhaps save.image(file=lala.rda, compress=T) followed by
load(lala.rda) to re-load it.

This wish has arisen since
1. This question is more appropriate for the BioConductor mailing list.
2. Any Affymetrix pre-processing can be split into background
correction, normalisation and summary stages. The combination of rma
background, quantile normalisation and median polish summary gives rise
to RMA. Therefore
Have you checked Section 5.14 (page 64) of R-extension titled Using
these functions in your own C code.
Section 5.7 tells you about some of the available subroutines.

This is not answering your question directly.
I usually use the BATCH command for running R non-interactively. You can
also use commandArgs() to get any arguments from the command line. For
more information, see help(BATCH) or help(commandArgs).

Alternatively you can use the combinations() function in gregmisc.
library(gregmisc)
n - 3
sapply(1:n, function(x) apply(combinations(n, x, LETTERS[1:n]), 1,
paste, collapse=) )
Here is the same code written with a for loop
n - 3
out - NULL
for(i in 1:n){
tmp - combinations(n, i,
1) Read the posting guide http://www.R-project.org/posting-guide.html
which tells you to
a) use a meaningful subject line
b) give a reproducible example. I cannot find plotData and there is a
syntax error (comma after the xyplot line).
2) The following example works fine for me
for(i in
m - matrix(1:9, nc=3)
a - list(m, m+10, m+100, m+1000)
sapply(a, function(mat) mat[1,1])

I am comparing two different algorithms in terms of speed and memory
usage. I can calculate the processing time with proc.time() as follows
but am not sure how to calculate the memory usage.
ptm - proc.time()
x - rnorm(100)
proc.time() - ptm
I would like to be within R itself since
Just finished updating and installing new packages from CRAN and
BioConductor (including annotation data) and am happy to say that my R
has just exceeded the 1 GB mark.

Try setting something like cex=0.5 in the plot. It works for at least
hclust. Here is a quick example using hclust to show how you can get
away with set the colours.
data(USArrests)
hc - hclust(dist(USArrests), ave)
plot(hc, hang=-1, cex=0.5)
labels - rownames(USArrests)[ hc$order]; n -
Out of curiosity, why is srt not respected in mtext ? See examples below
plot(1:10, xaxt=n);
par(srt=45)
mtext( paste(Point, LETTERS[1:10]), side=1, at=1:10 )
plot(1:10, xaxt=n);
mtext( paste(Point, LETTERS[1:10]), side=1, at=1:10, srt=45 )
It would be nice to have 'srt' as an argument in

plot(1:10, main=paste(x, eval(expression(Delta)), values))
plot(1:10, main=paste(x, expression(Delta, values )))
plot(1:10, main=paste(x, expression(paste(Delta, values

Using append=TRUE in write.table only appends rows (see example below).
You might be interested in a recent tread about appending to save()

Look into the code of power.t.test in the stats package. For example,
the sample size for two-sample t-test, two-tail testing and strict
interpretation of tail probability can be found by solving the following
