dear r-helpers,
it seems the colors in an automatically generated lattice legend
recycle after the 8th color, even when the user has set e.g.
superpose.symbol$col to be longer than 8. the following example will
illustrate what i mean:
z <- data.frame(x=rep(letters[1:15], each=4), y=rnorm(60),
that works beautifully. thank you, jim!

dear expeRts,
i would like to merge the data frame entries in a list. for example:
> #input
> myl <- list(q1=data.frame(id=c("Alice", "Bob"), grade=c(90, 49)),
q2=data.frame(id=c("Alice", "Chuck"), grade=c(70, 93)),
q3=data.frame(id=c("Bob", "Chuck"), grade=c(84, 40)))
David,
At the following URI you will find an R package called lmsqreg that
implements LMS quantile regression:

Adrian,
To prevent coercion to numeric, try:
mydata <- read.table("myfile", colClasses="character")

Dear Menghui,
You may consider looking in Luc Devroye's "Non-uniform Random Number
Generation". Despite its title, section XI.3.2 describes how to
generate bivariate uniforms. The book is out of print but Devroye
himself urges you to print it from his scanned PDFs(!):

Dear UseRs,
Could someone explain to me why the default behaviour of rank() is to assign the
largest rank to missing data

as opposed to what I would hazard would be the expected 2, 1, NA?

Dear R-help readers,
In R 1.8.1 it was easy to print the documentation for recommended packages: go
to the full reference manual (refman.pdf) and print the relevant pages, which
were contiguous. With R 1.9.0 some of those packages (e.g. "ts") have become
part of the "stats" package, and hence thei

Dear R-Helpers,
I would like to read an Excel .xls file via RODBC. I have successfully run
the example in p. 18 of "R Data Import/Export". The problem I am facing is
that Excel's ODBC driver seems to have a limit on the number of
fields/columns (output below). I haven't found any documentation on
