Sync files-from with delete
I have a local directory that I am trying to sync with a remote directory. That's fine, but there's a lot of data that is out of sync so I decided to make a local copy of the difference to then bring to the remote location. So I ran a dry-run between the two to generate a list of files in listOfFiles.txt Then I ran rsync from local to localBackup. rsync -av

parsing files for plot
Hi, I have many files containing one column of data. I like to use the scan function to parse the data. Next I like to bind to a large vector. I try this like: count<-1 files <- list.files() # all files in the working directory for(i in files) { tmp <- scan(i) assign(files[count], tmp) count<-count+1 } This part works! Now I like to plot the data in a boxplot.

HSM devices and FreeBSD
I am essentially asking the same question that Eirik Overby asked a couple of years ago. Is anyone aware of PCI-X/PCIe hardware security modules that are supported on FreeBSD? I have not seen any on the FreeBSD hardware compatibility lists. Again, as Eirik noted in his question, HSMs are not simply crypto accelerators (which are supported on FreeBSD), they also are a means of storing keys

Dual mono not stereo
Hi, If I want to encode two audio channels that are not related, audio from two different sources not stereo, is it best to create two instances of a single channel encoder or use one encoder with two channels? thank you, Paul.

celtenc two channels
Hi, To enable stereo in celtenc do I need to change anything other than #define CHANNELS 1 to #define CHANNELS 2 The reason is after I do this the audio sounds distorted. Please let me know if I need to do anything else or whether I need to investigate what's happening at my end further. Paul.

Config and other areas of struggle
Confused me for ages.. until one day! Which out of the listed machines (on the router) is the one you are needing the port forwarded to? Forward that machine to the port you require, I would have used a lower port number 8010 or another unused port.

Loc function in R??
Does anyone know which function (if any) will return the index of the true locations in a Boolean vector? For instance: A=c(1,3,5,7,4); B=c(2,4,77,3,3); X=A<B; So X is: > X [1] TRUE TRUE TRUE FALSE FALSE I'd like to know if there is a function that will tell me the locations of where the TRUE values are? for instance a vector that will list that the locations are at

large dataset!
Hi, I need to analyze data that has 3.5 million observations and about 60 variables and I was planning on using R to do this but I can't even seem to read in the data. It just freezes and ties up the whole system -- and this is on a Linux box purchased about 6 months ago on a dual-processor PC that was pretty much the top of the line. I've tried expanding R the memory limits but it

inverse F distribution in R?
Dear all, I'm looking for a function that calls the inverse F-distribution. Something equivalent to FINV in matlab or excel. Does anyone know if such a function already exists for R? (I haven't been able to find one.) Thanks for any leads. Best, Jennifer

extracting vectors from lists of lists
Good evening I often have as output from simulations a list of various values, vectors and matrices. Supposing that I then run said simulation several times, I often want to extract a particular result from each simulation for plotting and, ideally, put it in a matrix. A simple example v1 <- 1:5 v2 <- 6:10 other1 <- "stuff" other2 <- "stuff" set1 <-

VLAN's
Hi, I have a firewall running IPTABLES. I have tried to route sip traffic from my WAN(eth3) interface to a VLAN(eth2.2) interface, however the data will not route to the VLAN it keeps routing to the default interface(eth2). Does anyone have an idea as to what I need to look for? Regards Jennifer Botten ETECH Tel: +2787 150 5285 Fax: 086 638 2412 Mobile: +27 82

evaluating expressions with sub expressions
Hallo I'm having trouble figuring out how to evaluate an expression when one of the variables in the expression is defined separately as a sub expression. Here's a simplified example mat <- expression(0, f1*s1*g1) # vector of formulae g1 <- expression(1/Tm) # expansion of the definition of g1 vals <- data.frame(f1=1, s1=.5, Tm=2) # one set of possible values for
