search for: 1000th

Dear R users, I am a beginner to R. I generated 1000 samples with 15 data in each sample I tried finding the variance for each sample I used the code: m=1000;n=15 > r<-rnorm(15000) > for(i in 1:m){ x=data[,i] v=var(x)} what I got was just the variance for the last sample i.e. the 1000th sample but what I want is 1000 variance. Does anyone know what I did wrong?

...irectly from the R console itself, it takes about 3 minutes in my computer. I'm ok with that. Now, when that same code is ran from within a GUI we created using Perl (Tcl/Tkx) it's taking 25-30 minutes to run. Within the R code I inserted a line so that it writes a little file every 1000th iteration of the loop, so that I can follow the progress. I don't understand why it takes 10x longer when ran from Perl. I am not new to R, but I am new to using it within Perl or any other language. Is there a way to improve performance? What is the reason for the slower speed? I'l...

...at lie very close to the lines that would be drawn by R anyway if there were no datapoint for that time value. Since the values in my simulation are constant most of the time but sometimes have interesting "spikes" a simple data <- data[seq(1:length(data),1000),] to only plot every 1000th point does not work for me as it could remove some "spikes" completely or lead to aliasing problems. Is there any standard way to do this in R? The best thing I came up with so far is a function that judges if a row in the dataframe should be kept for plotting based on each points diff...

...#39;aa''. but if the query is ''aa aa'' than q first run is ''aa'' and second run is ''aa'' in first run it prints the result out but on second run the result is ''nil'' again. I can run 1000 run the first 999 is correct but 1000th run is nil again. what does realy cause this? -- Posted via http://www.ruby-forum.com/.

Guys, I need a clue here. The command I am using is: cupsaddsmb -H kaliklak -U Administrator -h kaliklak -v Lex_Z53 and despite the fact that the password used is correct the result is: [root@kaliklak root]# cupsaddsmb -H kaliklak -U root -h kaliklak -v Lex_Z53 Password for root required to access kaliklak via SAMBA: Running command: smbclient //kaliklak/print\$ -N -U'root%XXXXXXXXXX'

Hello Everyone, Would it be posiable to add a "keep alive" option to rsync. The problem I am having is that the connection is dropped while rsync is scanning the local directory. If "null" packets are send to the server every 60 seconds or so, the connection will stay up and the sync will work. Or maybe there is an option that does this already ? Thanks, Pieter De Wit

Dear All, I'm developing an R application running inside of a Java daemon on multiple threads, and interacting with the parent daemon via stdin and stdout. Everything works perfectly fine except for having some memory leaks somewhere. Simplified version of the R app: while (TRUE) { con <- file('stdin', open = 'r', blocking = TRUE) line <- scan(con,

...daries. If you force each Speex frame to be byte aligned you get significant padding loss (up to 7 unused bits per frame). And that is bad because it drives your bitrate up. I used a C program to determine good bit packing for each mode. This was able to ensure that bit padding loss is less than 1/1000th of the total bitrate for all available modes in the codec. In some low quality modes I was able to save 10% in bitrate. This came at a price though. Grouping several speex frames into one block makes it more difficult to use the ACM for low latency applications like Netmeeting. So if the ACM comb...

I have no hints, sorry... but give some more "data": I've changed the above to *print* the gc() result every 1000th iteration, and after 100'000 iterations, there is still no memory increase from the point of view of R itself. However, monitoring the process (via 'htop', e.g.) shows about 1 MB per second increase in memory foot print of the process. One could argue that the error is with the OS / p...

...amount, which would still end up being larger than the 160bit SHA1 we originally started using. In theory, a random hash chunk as small as 32bit could be considered sufficient for each page, which with the average Ogg page this means 4bytes vs 4kbytes of transfer when compared to the payload (1/1000th is a very good ratio). If 32-bits is used as a fixed number, an offset of 0 to 124 (or 128 w/ wrap) could be provided in one byte-field, followed by up to, say, 100 page hashes and still keep the message size under 500 bytes total, the rest of the message being about 34bytes plus the length o...

...e debug printk''s into do_hypervisor_callback() to see whether any callbacks are made at all. According to this, a vtimer interrupt does happen, but only every 10 seconds, which -as I guess- is far less frequent than it should be (The timer handler prints out the current time for every 1000th timer event, so it would take almost three hours before the first message ist printed). Also interesting is that whenever I hit a key on the keyboard, a timer interrupt is pending. It looks like the interrupt is somehow not "connected/enabled". Does anyone have an idea what to do? Ch...

Hi all: I've been working on porting Swfdec to Mac OS X on my own time. So far I'm making some progress; stuff is displaying and events are working. I still have a bit of work to do, but in the meantime, I have some questions: 1. How does one get the ability to commit things to the repository? I don't expect this right away; I'll probably just distribute the Mac OS X

Hi, I'm just considering buying two Telecoms grade Sun Netra's to run a lab-based VoIP solution. Not my immediate thoughts as a VoIP platform, but from what I've heard, they can run Linux, and run it well. Only thing is: The Wiki and the Whitepaper just state that Asterisk is for the x86 architecture, but has been compiled to run on PPC architectures. No mention of UltraSparc.
