Thanks for your advice, Gavin. I hope to comply with the posting guide this
time.
With "crashing" I meant that the R-session is simply terminated without an
error message (Vista, R2.6.1 and R2.5.1 with precompiled packages, sessionInfo
see below). I could reproduce the error on a linux machine (R2.5.1-1 for which
I have compiled the packages on my own). On the linux machine I at least get
the following error message:
*** caught segfault ***
address (nil), cause 'unknown'
Traceback:
1: .Fortran("xys", as.integer(m), as.integer(n), as.integer(p),
as.integer(R), as.integer(m + 5), as.integer(p + 2), as.double(x),
as.double(y), as.double(tau), as.double(tol), flag = integer(R), coef =
double(p * R), resid = double(m), integer(m), double((m + 5) * (p +
2)), double(m), as.integer(1), sol = double((p + 2)), dsol = double(m),
lsol = as.integer(0), xx = double(m * p), yy = double(m),
as.integer(s), PACKAGE = "quantreg")
2: boot.rq.xy(x, y, s, tau)
3: boot.rq(x[s, ], y[s], tau, ...)
4: summary.fcrq(model.powell, R = r)
5: summary(model.powell, R = 1e+06)
I used the following command to generate the model:
model.powell <- rq(y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9,
method="fcen", data=data_test)
summary(model.powell, R=1000000)
I used 1000000 replications to make sure that the error is triggered
I uploaded the data to www.esbf.de/quantreg/data_test.RData

Err, what does this have to do with Jared's reply to Max's posting about
suitable textbooks and R?
Please don't jump on a thread to ask your own question. Start your own
thread.
If you want people to help you with your problem, you are probably going
to have to give a reproducible example - "my R session crashes" is way
below what is requested in the posting guide. Even the statements about
what you did are not enough - people need to be able to reproduce your
problem on their machines.
Read the posting guide (URL in the footer of this email) and resend a
message to the list - a new one mind, so you start a new thread. And
make sure you include a reproducible example. If you can't send your
data, try it with one of the data sets that come with quantreg and if it
fails with that also, use that data set in your example.
You should also consider contacting the maintainer of quantreg.
