similar to: discrete event simulation - "factory" with rework

Good morning, I've searched high and low and I've tried many different ways of doing this, but I can't seem to get it to work. I'm looking for a way of vectorising a "running balance"; i.e. the value in the first row of the dataframe is zero, and following rows add to this running balance. This is easy to write in a loop, but I can't seem to get it working in

Hi Folks, I'm trying to learn R. One of my intentions is to do some Monte-Carlo type modelling of road "accidents". Below, to simplify things, I've appended a little program which does a 'monte-carlo' type simulation. However, it is written in a way which seems a bit un-natural in R. Could someone help me make this a bit more R-ish please? Or is there a

Good afternoon, This is possibly a windows only bug, definitely of comparatively low importance - but for the sake of completeness here we go. I've searched http://bugs.R-project.org/ etc., but can find no mention. For RGui.exe, the CPU usage goes to 100% for certain dialog boxes for the duration that the dialog box is visible, e.g. * check CPU usage is low * On the RGui.exe menu chose

Is there a function in R to calculate the generalized determinant of a singular matrix? - similar to the ginv() used to compute the generalized inverse. I can't seem to find any R related posts at all.

Good evening, Spotted a very minor spelling mistake in the source for the grep help. And thanks to R-Core for all their work - it's a tribute to R-Core, that these sort of "problems" are rare indeed. Best regards, Sean O'Riordain Dublin sean at sean7:~/R/RSVN/R/trunk/src/library/base/man$ svn diff Index: grep.Rd

Hi All, I am attempting to simulation an inventory model on R and I am having some problems. I believe the problem is when I define my demand rate is stays constant throughout so when I do need to reorder the model does not recognise it as I have the initial supply arrival time set to infinity at the start as no order has been played but I have an if statement saying, if the level falls below a

Followups set, hesitantly, to gmane.linux.redhat.fedora.general I thought I had posted this to both these groups, but my newsreader doesn't show it in either. I have three Garmin GPSs (an Etrex Vista and two Rino 120s), which I want to use under Fedora 11 Linux with four PCs, and two IBM- reconditioned Thinkpads, T30 & T42. Garmin software suites (Metroguide USA and Topo US 2008)

For years, I could install, and sometimes run, legacy private map software under Wine. But in order to connect it with my GPSs, I had to keep a separate hard drive with XP, and do that there. Then came a brief time when I could also actually make my Garmin GPSs talk with the software under Wine. I transferred all my data to it, and gleefully wiped XP off my machine. Then the connecting

I'm just getting started with R, having a lot of original work on modeling and exploring the simulation by MCMC. I want to simulate the prior and the posterior distribution of Dirichlet Process by MCMC. Is there anyone in NYC that might be a good tutor for me? -- Dr. P.

Dear List, I am reading a method and am unsure how to do something similar, so have come here for advice! I have a observed value and a expected value generated from a null model. I am looking to see if observed - expected is significantly different from zero. So in the method in the paper it states: " .. significance of difference from zero was tested with Markov chain Monte Carlo

Dear all, I am trying to simulate from discrete uniform distribution. But I could not find any in-built code in R. Could anyone help me please? Thanks in advance for the time and help. Cassie [[alternative HTML version deleted]]

Good morning, I have currently 63 .csv files most of which have lines which look like 01/06/05,23445 Though some files have two numbers beside each date. There are missing values, and currently the longest file has 318 rows. (merge() is losing the head and doing runaway memory allocation - but thats another question - I'm still trying to pin that issue down and make a small repeatable

I tried thinning of the mcmc run with 500,000 iteration. It looks like 100 or 200 is enough to remove the autocorrelation of a1 and tau.

Hi All, I have two old S100 units (the blue ones, not the newer black ones). I am trying to reset these to factory default using the following instructions, but it is not working. Does anyone have any other suggestions to reset this model of the adapter? Tried this: 1. Remove all of the cables, except for the power cable. 2. The factory reset button is next to the RJ45 jack. Press and hold the

Hello, Consider MCMC sampling with metropolis / metropolis hastings proposals and a density function with a given valid parameter space. How are MCMC proposals performed if the parameter could be located at the very extreme of the parameter space, or even 'beyond that' ? Example to express it and my very nontechnical 'beyond that': The von Mises distribution is a circular

As most of you know, I've been trying to make GPSs and topo maps usable under Fedora Core 4 linux, using CrossoverOfficePro (CXO) 5.0.1. I've belabored nine or ten specialized lists for six or eight weeks, parcelling out pieces of the problem wherever I hoped they might arouse interest and knowledge. I've gotten invaluable help and encouragement from all of them, on the lists
