Dear list, When compiling the R-2.3.0 on FC4 x86_64, I got the following errors: make[3]: Entering directory `/project/scratch3/ligroup/wuming/src/R-2.3.0/src/main' gcc -Wl,--export-dynamic -L/usr/local/lib64 -o R.bin Rmain.o CConverters.o CommandLineArgs.o Rdynload.o Renviron.o RNG.o apply.o arithmetic.o apse.o array.o attrib.o base.o bind.o builtin.o character.o coerce.o colors.o complex.o

Dear list, Given a vector of logical values, say >a <- c(TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,TRUE,TRUE,TRUE) Are there any R functions that can tell whether there are two or more "TRUE" in a row in this vector? Thanks, Wuming

Dear list, This question is about Hidden Markov Model. Given a transition matrix, an emission matrix and a sequence of observed symbols (actually, nucleotide sequences, A, T, C and G), I hope to predict the sequence of state by Viterbi algorithm. I searched R repository for related packages. msm package has function viterbi.msm (as well as very good document), but it only works for

Hi, OK. I tried your suggestion. I modified the dovecot config file "10-logging.conf", like so: log_path = syslog and mail_debug = yes It appears that the logging goes to "/var/log/maillog", not "messages" as I expected. Restarting service dovecot produces info in the "maillog" file showing the restart: ... Jan 22 15:20:14 coe dovecot: imap: Server

Hi, I have a question. I have dovecot 2.0.9 running on a CentOS 6.6 email server for a small department, ~15 users. amavis and postfix are also enabled. It appears that amavis invokes spamassassin, which tags incoming spam email. All email is then put into users local inbox directory, regardless of spam tag X-Spam_Flag value of YES or NO. I want instead to redirect spam to a special directory.

Dear list, In some places (for example, http://en.wikipedia.org/wiki/Support_vector_machine) , the polynomail kernel in SVM is written as (u'*v + 1)^d, while in the document of svm() in e1071 package, the polynomial kernel is written as (gamma*u'*v + coef0)^d. I am a little confused here: When doing parameter optimization (grid search or so) for polynomial kernel, does it need to tune

Dear list, I installed odesolve package (0.5-15) in R 2.3.1 in a Solaris server (Generic_118558-11 sun4u sparc SUNW,Sun-Blade-1000). The installing progress completed without errors, though several warnings like "Warning: Option -fPIC passed to ld, if ld is invoked, ignored otherwise" were outputed. However, when loading the odesolve package by library(odesolve), following error

I want the curve to touch the y axis like the curve touches the upper boundary. How can I eliminate the margin between axis and curve on the left side? x1 <- c(1,2,3,4,5) x2 <- c(2,4,6,8,10) mod <- lm (x2~x1) hm <- function (x) (mod$coe[1]+x*mod$coe[2]) plot.new() # ... box() curve (hm,lty=1,add=T,xaxs="i",yaxs="i") (R 2.8.1) -- Sensationsangebot verl?ngert: GMX

Hello, I have installed GlusterFS one month ago, and replication have many issues : First of all, our infrastructure, 2 storage array of 8Tb in replication mode... We have our backups file on this arrays, so 6Tb of datas. I want replicate datas on the second storrage array, so, i use this command : # gluster volume rebalance REP_SVG migrate-data start And gluster start to replicate, in 2 weeks

Dear list, I have a problem on calculating the standard error of Goodman-Kurskal's gamma using delta method. I exactly follow the method and forumla described in Problem 3.27 of Alan Agresti's Categorical Data Analysis (2nd edition). The data I used is also from the job satisfaction vs. income example from that book. job <- matrix(c(1, 3, 10, 6, 2, 3, 10, 7, 1, 6, 14, 12, 0, 1, 9,

Hi, Is there a way to convert a matrix into a vector representing all permutations of values and column/row headings with native R functions? I did this with 2 nested for loops and it took about 25 minutes to run on a ~700x700 matrix. I'm assuming there must be a smarter way to do this with R's vector commands, but being new to R, I'm having trouble making it work. Thanks,

Hi all I've written a basic COM32 module that checks (using the DMI example code) the product and BIOS and if the BIOS is not at the required level, is supposed to exit and boot using a DOS floppy image to flash the BIOS. The problem is that I can't work out how to call the DOS floppy image. Looking at the website, I see "Run Command" AX=0003H via int 22. The image name will

This is simple (I am sure) but how do you get the id of the inserted element after the element has been save? I thought it was something like this: @product = Product.new(params[:product] if @product.save add_image(product.id, params["image"]) flash[:notice] = ''Product was successfully created.'' redirect_to :action => ''list_products'' end

Hi all Is there any way to extract information (like what dmidecode provides) from within PXELINUX and, based on this information, selectively perform an action? What I'm trying to do is provide a method of flashing the BIOS of our HP Linux workstations but different workstations use different methods of updating the BIOSes. For example, the xw9300 uses 'rompaq' where the xw8400

Hi all I'm trying to resolve a problem that's recently popped up by turning on auxillary VLANs for our Linux workstations. The problem shows as DHCP failling for anaconda (but always succeeds for PXE). I tried adding 'ipappend 1' to the pxelinux config files but had no joy. I'm thinking that if I write a COM32 module that adds "ip=1.2.3.4 gateway=1.2.3.1

Hi all I'm guessing this is a little off topic but here goes... We use PXELINUX and kickstart to automate our RHEL deployments and updates. Recently we started using PXELINUX/memdisk and an MS-DOS image to update the workstation BIOS'es. After selecting <F12> (network boot) and picking the update BIOS option, the BIOS is flashed, BIOS configuration made standard and then the

I have this in my controller... @tech_standards = TechStandard.find_by_sql("SELECT * FROM tech_standards WHERE subpoint <> 0") Everything is fine except when I look at my view I still get supoints that are 0. When I run this query in my query browser I don''t. View: <select name="resource[tech_standard]" id="tech_standard">

Hi all I've googled but can't find an answer to my question. I have two data centers. Currently, I have a replica (count of 2 plus arbiter) in one data center but is used by both. I want to change this to be a distributed replica across the two data centers. There is a 20Mbps pipe and approx 22 ms latency. Is this sufficient? I really don't want to do the geo-replication in its

Interesting table Karan!, Could you please tell us how you did the benchmark? fio or iozone orsimilar? thanks Arman.
