Changing strip widths in lattice plots
Hello R users,
I'm using xyplot (lattice) to plot some data. Unfortunately, the text that goes
into each strip is often too big to fit. For instance, one of the factors may
be labelled "Satisfaction with waiting time" which is too wide to fit. If I use
split.string() to wrap it onto two lines it is then too high to fit in the
strip. I'd prefer to apply split.string on the

Paid support for R?
Dear R users,
Sorry if this has been discussed before.
I was recently looking at the MySQL site and saw that they offer various levels
of paid support. The support options range from basic email support (USD200)
through to extensive telephone support from the development team (USD10000).
These are annual prices.
This is something I would be happy to see available with R (maybe it is?). My

Re: Universal legend in plot
Is your data such that it can be restructured into a form amenable to a
lattice plot, such as xyplot()? In that case, the legend (key in lattice)
can be placed pretty much anywhere.

Australian CRAN mirror
One of the CRAN mirror links for Australia is not correct,
and I'm wondering how to have it updated.
The incorrect address is http://cran.mirror.aarnet.edu.au/
and the correct one is http://mirror.aarnet.edu.au/pub/CRAN/.

Importing Data
Dear David,
If you have sufficient RAM you can increase the amount R uses by adding
the switch "--max-mem-size=1024M" to the command you use to start R
(change 1024 to whatever amount of RAM you have).
If you don't have lots of RAM, you may have to draw just a subset of data.
If you're developing or testing a model this will be okay, as long as you
choose
enough samples.

Aggregate: assembling the "by" part on the fly
Dear R users,
I'm having trouble using aggregate() and would
greatly appreciate your advice. I am using R 1.5.1
on Windows 2000.
I want to call my function in the following way
extract.data(x=dat[, "Age", "Year"])
where extract.data() uses aggregate() to count the number
of cases for each combination of "Age" and "Year".

Christmas tree graphs
Hello R users,
I wish to draw a type of horizontal bar chart for two groups (males and
females). The values for one group will start at the y-axis and point to the
left, and the values for the other group will start at the y-axis and point to
the right. If you're (un)lucky, the resulting graph can assume the shape of a
Christmas tree.
The data are

Fast R implementation of Gini mean difference
I have written the following function to calculate the weighted mean
difference for univariate data (see
http://www.xycoon.com/gini_mean_difference.htm for a related
formula). Unsurprisingly, the function is slow (compared to sd or mad)
for long vectors. I wonder if there's a way to make the function
faster, short of creating an external C function. Thanks very much
for your advice.

Trouble reshaping some data
I would appreciate some advice on the following task. I have
some data that currently looks like this:
t1 <- data.frame(id=c(1,1,2,2),
aspect=c("A","B","A","B"), score=c(10,9,11,12))
I'd like it to look like this:
id A B

Updating selected variables in a data frame
Dear list,
I'd like to update certain rows/columns in a data
frame with new values. The application is that
survey respondents may give an answer of "Other"
to a categorical question and then provide some
text describing what they mean. This text is then
reviewed and placed into a category. These edits
or recodes then need to be merged back into the
main dataset.

count.fields vs read.table
Dear R-help,
I am using R 2.1.1 on Windows XP.
I have a tab-delimited data file that has been exported by SAS. The file is reasonably big so I
apologise that I can't give a good toy example. I do this:
table(count.fields("t1.txt", sep="\t", quote="\""))

So I have 809 lines, each with 248 fields.

R and C++ compared with only C++
My computer is a pentium 4 running at 2.4 GHz.
My R is 1.7.1
I have written a program in R that calls C++. The program spends most of the
time in C++ ( > 90% ). R basically deals with output and input.
How slower can this be compared with the program I would get from rewriting
everything in C++?
Thank you.

'format' problem
Dear R experts,
format(12345678, digits = 2)
gives
[1] "1.2e+07"
while
format(1234567, digits = 2)
gives
[1] "1234567"
but I'd like the last number to be represented as "1.2e+06" string too.
Where am I wrong?
Thanks,

Read.table for macs
Dear All,
I've been using R for windows for a while, without too many problems.
However, I'm forced to use the MAC OS system for teaching, because our
teaching labs are mac only (not my idea!!). I have a very basic problem,
but one that doesn't appear on the FAQs. I simply want to import data
from a spreadsheet. I'm using exactly what works fine on Windows, namely:

graphic widow overwrite
Hi,
I am running a loop to plot multiple plots. In s-plus,
it shows multiple pages in the graphic window to allow
checking on each plot. but in R, the next plot always
overwrite the previous one, so i can only have the
last plot produced, is there a way to have multiple
pages in the graphic window just like S-plus does?
Thanks

adding option in the Windows installer for --internet2
[Not sure if such wishlist item should go to R-help or R-devel...]
It would be nice if an option can be added to the R for Windows installer
that will add the --internet2 option to the command line in the shortcut
that gets created. Also, is it possible to make that an option that can be
set at the R prompt, or perhaps even better, as the default no matter
how/where R is started? For those of
