I have a 47k x 47k adjacency matrix that is very sparse (at most 30 entries per row); my textual representation therefore is simply an adjacency list of connections between nodes for each row, e.g. node connections A B C D E B A C D C A E D A E A F F E G H I'd like to import this into a dataframe of node/connection (character/vector-of-characters) pairs. I've experimented with

Hi all, I attempted to add an EL5.1 client to our puppet server (EL5), and after signing the client cert, got the error "Certificates were not trusted: hostname not match with the server certificate" I found the mailing list discussion and the relevant page: http://www.reductivelabs.com/trac/puppet/wiki/RubySSL-2007-006 As far as I can tell, my puppermaster''s cert CN matches

I've got a HP dv8000 laptop. Setting up the wpi driver for wireless freezes the system on boot with the following error: wpi0 requested unsupported memory range wpi0: could not allocate memory resource It lists a pcbi device (pcbi4 i think) and an actual memory range, but since I have to reboot using kernel.old the /var/run/dmesg.boot is wiped with the info. Is there anyway to grab the info when it freezes when it reboots? I'm running i386 7.1-PRERELEASE from today. pciconf and the kernel are below. Let...

I've posted a message twice to this list, and never seen it appear yet ... perhaps this one will go through ... ? -- Aaron J.

I am looking for information on experimentation with the use of R in the teaching of statistics and science in schools. Any leads would be very welcome. I am certain that there is such experimentation. I've made this inquiry on r-sig-teaching, with no response. John.

Is there anyway I can write a script which feed input datasource from stdin and let R process it (maybe frequency report) then output the report to stdout? I can't seem to find much info on documentation or FAQ on this topic. Thanks!

Can anybody tell me if there is an R implementation of the Fligner-Policello robust rank test? Thanks, Elisabetta

[ Not sure why, but the first time I sent this it never seemed to go through; apologies if you're seeing this twice ... ] I have some fully functional code that I'm guessing can be done better/quicker with some savvy R vector tricks; any help to make this run a bit faster would be greatly appreciated; I'm particularly stuck on how to calculate using "row-wise" vectors

I have a MLE task that for a small number of parameters finishes in a reasonable amount of time, but for my "real" case (with 17 parameters to be estimated) either takes far too long (over a day), or fails with "computationally singular" errors. So a) are there any parallel implementations of optim() (in R or otherwise) and b) how can I make my function more robust?
