Generate a clustered pattern in [0; 1]2 as follows: (a) Generate nc, say 20, independent cluster centres (which can be called parents) that are distributed i.i.d. uniformly in the unit square; (b) then n daughters are assigned i.i.d. uniformly to these parents and such that each daughter is located i.i.d. uniformly in a disk of radius r = 0:1 centred at her parent, under the periodic boundary

Hello ! I have a quick question about loops. For example, I have a 1 * 1 square and its inscribed circle tangent i, whose radius, of course, is also 1. The loop here is as the following: generate n points, say 5, in the square randomly repeatedly until we have five in total in the circle, then we stop, otherwise we continue. I do not know how ! Help me Please ~ Thank you very much for

Hello! I have a question on uniform distribution. I want to plot n, say 20, points, uniformly distributed, in a circle, with radius=0.1 and center,say, (0.4, 0.8) I do not know how~ Thank you for your time. Yours Wolfgang Amadeus [[alternative HTML version deleted]]

Friends-- I'm stumped! Cannot get mount.cifs to work over a tun connection. How would you trouble-shoot this? 1. It cannot be openvpn causing the problem: I can ping across the connection both directions on all machines. 2. It cannot be samba causing the problem: I can mount.cifs the smb shares on the lan (using the identical credentials file) without any issue. 3. Have iptables

Hi it smells like a homework, this list has no homework policy. Anyway, maybe the sample approach could be used. Generate x,y coordinates - ?expand.grid sample n centers - ?sample select all points within defined area - ?point.in.polygon, package sp select desired number of points - ?sample Cheers Petr > -----Original Message----- > From: R-help [mailto:r-help-bounces at r-project.org]

Hallo I am going through the paper on Torus randomization by Kyle E. Harms torus randomization is an alternative to Chi-sq test of Independence When the assumption of independence within the groups is violated i want to know that Is there any library regarding torus randomization Someone said me that its in Utility.r but i could not find out this please help me in this regard Shubham Surendra

Dear R users. I have data observed on the surface of a torus, and am trying to fit the nonlinear regression using the geodesic equation on a torus. Could anyone give me a helpful advise on this problem? I would definitely appreicate your reply. Sincerely, SUNGSU KIM [[alternative HTML version deleted]]

Hi all, I am running R 2.5.0 under Windows XP Media Center Edition. Here's a problem that's been stumping me for a few days now, and I can't find anything useful in the archives. I am using voronoi.mosaic (tripack package) to create proximity polygons for a study of vegetation competition and dynamics. The points lists are read in from a file for each plot, then 8 duplicates

Dear Dr. Bivand and R-users, I have a 5 by 5 grid, say, location[1:5,1:5], and I want to know the indices of 8 neighbours of each cell. For example, for location[2,2], its neighbour coordinates are [1,1:3], [2,1], [2,3] and [3,1:3]. Sometimes I also need to remove edge effects (torus = TRUE). I have tried "cell2nb" function in your spdep package. Here's my example: > neigh

Hi all, I'm currently implementing quasi random generation (torus) on R (package randtoolbox available on CRAN). Even if it is not a great idea, I decided to use the machine time to initiate the seed. So when the seed is not specified by the user, the pkg uses the time machine time. Hence the following R code should produce different uniform variates : > for(i in

Hello, I have 2D-data on a torus, i.e. they are scattered within [0:2pi) and are supposed to be periodic with period 2pi. Is there a way in R for a kernel density estimation for such data? I found this article http://www.dmqte.unich.it/personal/dimarzio/density46.pdf but a) I don't fully understand the article (my knowledge in statistics is poor) b) I did not understand which Eq.

Hello While searching the archives and googling for : -login script to map drives according to group membership I saw lots of complicated solutions (on-the-fly scripts, group directories) etc. but the following works very well for me: I downloade dthe ifmember.exe from the microsoft website, and stuck it in the netlogon directory (not the scripts directory)

Here is the patch with my changes. Most work went into the decoder. I just changed on the encoder if something was nessesary to build the library. You can find the patch here (quite big).. http://torus.untergrund.net/code/theora_mmx_vc2005.diff Please let me know if the encoder works without problems. I just did a very brief testing of it. The decoder has been tested against the test

Hi, this reminds me of my troubles of setting up samba BDC at remote company branch. Connection was done by IPSEC tunnel between 2 mikrotik routers. Thing was, ipsec supports only unicast, but not multicast,nor broadcast. Solved it by adding L2TP tunnel that support the above mentioned mechanisms. So ended up with the l2tp (which has very weak encryption and is very old and vulnerable)

Sorry to all bothering you with a trivial question: I am using R (rw0630 for Win32) and am simply unable to read-in the *.txt data. I've tried to copy the file (prum.txt) to different directories of rw0630 but get uniformly the answer "object "prum.txt" not found". Which is the default directory for read.table() ?? Thanks! Z.

Afternoon all, After doing some test on my asterisk box I can successfully receive calls to my Asterisk PBX to a SIP phone from The Telstra PSTN network Dial out from a sip phone is also not an issue, all calls connect and terminate normally. If I call the Asterisk PBX say from PSTN in Zap1-1 and out through ZAP2-2 back to the PSTN (after entering the correct pin off course) the card does not

Can someone explain to me what is happening here: ~ $ touch foo ~ $ ln foo bar ~ $ ls foo bar bar foo ~ $ mv foo bar ~ $ ls foo bar bar foo I try to move a file over a hard linked copy of itself and the move fails, but there is no error. Is this the intended behavior? -- Ben Escoto

Hi, We are haing some serious issues trying to configure an OCFS2 cluster on 3 SLES 10 SP2 boxes running in VMware ESX 3.0.1. Before I go into any of the detailed errors we are experiencing I first wanted to ask everyone if they have successfully configured this solution? We would be interested to find out what needs to be set at the VMware level (RDM, VMFS, NICS etc) and what needs to be

Hi, Apart from the Calysto project ( http://www.cs.ubc.ca/~babic/index_calysto.htm), is there any other static code analysis tool based of the LLVM framework ? Calysto may be great but it seems that the source is not available (yet?). I was quite excited by Oink/Elsa few years ago but the project is almost dead even if the C++ parser is far from being complete. It seems to me that everything is

Hi all, I am sorry if this is a very basic quesion, but I have no experience with analyzing spatial data and could not find the right function/package quickly. Any hints would be much appreciated. I have a matrix of spatial point patterns like the one below and want to find the number of independent components (if that's the right term) in that matrix (or in that image). x=matrix(c(0,1,0,0,0,
