I am trying a simple toin coss simulation, of say 200 coin tosses. The idea is to have a data frame like so: Experiment# Number_Of_Heads 1 104 2 96 3 101 So I do: d <-data.frame(exp_num=c(1,2,3)); /* Just 3 experiments to begin with */ d$head_ct <-sum(sample(0:1,200,repl=TR...

All, I've devised a way to toss a coin three times and record the number of heads, then use the table command to summarize the number of time 0, 1, 2, or 3 heads were obtained. n <- 100 x <- sample(c("H","T"),3*n,replace=TRUE) dim(x) <- c(3,n) num_heads <- apply(x,2,function(x) sum(x=="H&quot...

Does anyone have a Sipura 3k running, and using the FXO? I've got things working right, but if I try to toss a *67 in the dialplan, it seems the sipura is throwing a 403 forbidden back. For example: exten => _91NXXNXXXXXX,3,Dial,SIP/sipura1pstn1/${EXTEN:1} works fine exten => _91NXXNXXXXXX,3,Dial,SIP/sipura1pstn1/*67${EXTEN:1} does not (even if I toss a couple Ws in) I can't seem to get it...

Hi! I'm taking a course that requires some programming background, but I'm a complete novice in the field. when asked to generate a list of 20 uniform random numbers, is it alright if I put in >randu, and just copy-paste the first 20 numbers?? Or is there, as I suspect, a better way of calling out exactly 20 uniform random numbers?? I'm also unable to solve the following problem:

Well, I've now tried just about every permutation I can think of - including using the ATLAS lapack (instead of generic), in various combinations with ACML, or generic BLAS, or ATLAS blas. No matter what I do, so long as I have lapack of any flavour, I get the 'stats error' with make check. And, it always seems to throw the error at the same point in the stats test file (an svd in

Can a single random number be generated in R? I have an exercise that wants to simulate coin tosses, and I cannot seem to find a good example of the use of random number generation in R. Any help? Joshua Gramlich Chicago, IL

There was a thread a few months ago that tossed around some ideas for using a cisco phone for intercom or paging. I don't have any ip phones, and wondered if anyone had any luck getting intercom or paging to work on the cisco units. Do any of the (cheaper) ip phones have a way to support intercom or paging? I presume that it's no...

...uis - I'm quite interested in using your repo for Samba support on 18.04. You note there's some detail on it on the github site - but I don't seem to find it. Also - while I know it's all just best intentions etc - is this something you intend to do for a while? [I'd be glad to toss some $$$ your way to help, if that's helpful. I'd toss some bucks to SerNet - but while the costs aren't massive, they do charge quite a lot for small shops, when you add the Sernet fees over, say, five years - for a few servers.] Recap: 1) Is this something you intend to do for a whil...

Hi, Reading about a "Heads and Tails" game in http://www.dartmouth.edu/~chance/teaching_aids/books_articles/probability_book/amsbook.mac.pdf Introduction to Probability (Example 1.4, pp. 5-8). You toss a coin 40 times. If heads, Peter wins $1, tails, he loses $1. I think I can do that ok with: winnings <- sum(sample(c(-1,1), 40, replace=TRUE)) But I have to do it 10,000 times and I have to record and collect the winnings. In other languages, I would probably use a for loop and "push&quo...

...y of tokeep=4 in /etc/yum/pluginconf.d/installonlyn.conf will cause yum to leave the working kernel in place through 2 more upgrades. Aside from setting tokeep to an insanely large value, is there any way to insure that yum will concern itself only with installing updates, allowing me to deal with tossing the old stuff? Also, is my understanding of the "tokeep" value in installonlyn.conf correct? Thanks! --

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usern...

I'm copying all my archives from one imap server on one machine to the imap-ssl dovecot server on another machine. After a bit, there's an error that's tossed up on my mozilla client that says the imap server couldn't complete the operation with the message append aborted. It keeps popping up after anything from 50 to 300 emails. Last night I was able to move ~12000 emails from one machine to the other without the ssl enabled. Any hints on wh...
