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

Is there a method to save a large and complex R object (either as a binary or text file) so that it can be loaded and reused at a later time? Specifically, I am creating large lists (several thousand elements), each element of which is either a vector or a matrix (with ~ 2000 rows). The dimensions of the matrices are not all the same. My ideal would be a set of functions of the form obj

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

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

I have a set of data that is not normally distributed and for which I need to build a model. So, I tried the lrm function from the design-package. The first run went well, and I got the following results: Wald Statistics Response: RVCL2PROC.mott Factor Chi-Square d.f. P TTV.mott (Factor+Higher Order Factors) 69.01 4

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

Tried with http://zhongshuobeijing.dyndns.org:7000/streamname.m3u but was blocked. And at last resolve: http://139.168.32.224:7000/streamname.m3u 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. cheers, iain On Wed,

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.

No - icecast can't work miracles! The underlying technology of the internet (the way it is at present, at least) only allows a packet of

thanks geoff - Yes, I had disabled the <alias source="/" dest="/status.xsl"/> in the config. 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:

Dear R list I have an m * n matrix P and a vector V of length n containing indices for rows in P. For each of the m columns I want to extract the value in the row specified by V, and put these values into a new vector W of length n. At present I am doing this with a for.... loop, but I imagine there is a faster way that doesn?t involve loops. If anyone knows the way I would be most grateful.

Dear all, I'm asking this question again as I didn't get a reply last time: I'm doing a survival analysis with time-dependent covariates. Until now, I have used a simple Cox model for this, specifically the coxph function from the survival library. Now, I would like to try out an accelerated failure time model with a parametric specification as implemented for example in the survreg
