max length of a factor variable
Hi
Is there a maximum length for the character string representing a level
of a factor? I have a set of several million variables, each a factor
of length 19. Each factor level is a character string which in some
cases can be many thousands of characters long. I am trying to find out
why my analysis fails - I just wanted to rule out the possibility that
the internal factor conversion has a

survreg with numerical covariates
Does anyone know if the survreg function in the survival package can fit
numerical covariates ?
When I fit a survival model of the form
survreg( Surv(time,censored) ~ x )
then x is always treated as a factor even if it is numeric (and even if
I try to force it to be numeric using as.numeric(x). Thus, in the
particular example I am analysing, a simple numerical covariate becomes
a factor

load ing and saving R objects
Does anyone know a way to do the following:
Save a large number of R objects to a file (like load() does) but then
read back only a small named subset of them . As far as I can see,
load() reads back everything.
The context is:
I have an application which will generate a large number of large
matrices (approx 15000 matrices each of dimension 2000*30). I can
generate these matrices using an

qr with missing dependent variables
Dear R-help
We have a regression problem which could be solved elegantly if we could
figure out how to get the R residuals() function to accept missing
dependent variables.
We have ~20000 gene-expression vectors y, each being measured on the
same set of individuals, but each having a small random number of
missing values.
For each expression vector we wish to search across the genome

substitution in expression
I have been struggling with this problem for a while and I hope someone
could help me. Or if someone could point me to a section in the manual I
would be grateful.
x <- "my"
plot(1:10, main=expression(paste( x, Delta, "values" )))
Q : How do I get the title to say "my (triangle symbol) values" ?

Samba 'stops' access to a file
I am running Samba on Solaris 2.6 and am connecting to it

the database is initially accessed without problem but part
way through processing I get the report that the database
file cannot be accessed since it is exclusively opened by
another user. I cannot then read the database at all until

load constraints
hello
Another beginners question..... I've been googling through the icecast
archives looking for information on how icecast handles multiple
clients. Haven't been able to find what I'm looking for.
Could someone please explain (or direct me to links) what happens to the
upload bandwidth of a box running icecast, when more than one client
connects? For example, if a box on a 128kbps

icecast & china
hello list
I'm preparing to do a sound project in china where I hope to broadcast
an mp3 stream using Icecast2. I've set up test system (outside China)
and it seems to be working happily (using Pd to generate audio and the
extension "shoutcast~" to stream to the icecast server).
I've asked a few people in china to tune into these broadcasts and have
run into problems.

Stats package
Hi
The cor function in the stats package calculates the correlation between
columns of data, does anyone know if it is at all possible to calculate
the correlation between rows instead ?
Or is there an appropriate package or function that is more appropriate
I'd like to calculate spearman & pearson correlations between rows.
Many thanks
Jason

is that what you mean? no, perhaps you mean the localhost? "bicho" is
its name. Pardon me if i'm confused on this.
Will also, tomorrow, try your suggestion of port 443 and Ross'
suggestion of the web port.

relay icecast to shoutcast
thanks geoff - Yes, I had disabled the <alias source="/"

To answer your question: If the mountpoint is set to "radio.mp3" and the
host tag is set for a local broadcast. ie.:
<hostname>localhost</hostname> (for testing purposes), this is what
happens when I enter "http://localhost:7000/" into a browser:
