similar to: having scaling problems with a histogram

Dear All, According to the Sturges rule, the number of classes of a histogram is the closest integer to 1 + logb(n,base=2) where n is the number of observations. The function hist(), by default, uses the Sturges rule. However, the code x <- 1:200 hist(x) produces a histogram with 10 classes and not 9 classes as determined by the Sturges rule. What am I missing? Thanks in advance, Paul

Hi Folks, I'd like to know how hist() decides how many cells to use when it ignores my "suggestion" to use say 'hist(...,breaks=50)'. More specifically, I have the results of 10000 simulations, each returning an 8-vector, therefore 8 variables each with 10000 values. Some of these 8 have somewhat skew distributions. Say one of these 8 variables is X. I ask for H <-

Dear list, I'm trying to do a set of generic functions do make contingency tables from data.frames. It is just running "nice" (I'm learning R), but I think it can be better. I would like to filter the data.frame, i.e, eliminate all not numeric variables. And I don't know how to make it: please, help me. Below one of the my functions ('er' is a mention to EasieR,

Hi All, I would like to make an invitation to make a collective package with all functions related to TABLES. I know that there are many packages with these functions, the original idea is collect all this functions and to make a single package, because is arduous for the user know all this functions broadcast in many packages. So, I think that the original packages can continue with its

Hi folks I'm trying to plot a normalized frequency histogram of some data. After checking the docs, it seems there is no built in feature for this. from the definition for normalized frequency, I need to divide the relative frequency by the size of the intervals being used. So I could divide the series by this interval length, and then plot the relative frequency. The problem is

Hi Group, I've a vector of 1000 numeric values for which I want to draw a histogram. I've read this vector into R with no variable name.I mean only the 1000 values, which makes V1 the name of the variable by default?? Then I tried > hist(V1, breaks = "Sturges", +      freq = NULL, probability = !freq, +      include.lowest = TRUE, right = TRUE, +      density = NULL, angle =

Hi, I'm plotting a multiple histogram using the function multhist {package plotrix}, something like: library(plotrix) mh <- list(rnorm(200, mean=200, sd=50), rnorm(200, mean=250, sd=50)) multhist(mh) In this graph y-axis represents the frequency of observations.... but I would like it to be scaled into relative frequencies, does anybody know how to do this with multhist or similar

Dear all, I am a newbie in R and could not find help on this problem. I am trying to plot an histogram with probabilities in the y axis. This is the code I am using: #TLC uniform n=30 mi=1; mx=6 nrep=1000 xbar=rep(0,nrep) for (i in 1:nrep) {xbar[i]=mean(runif(n,min=mi,max=mx))} hist(xbar,prob=TRUE,breaks="Sturges",xlim=c(1,6),main=paste("n =",n), xlab="Média",

Hello, currently I''m working on a JavaScript-on-screen-keyboard for use with touch screens. To autocomplete inputs I want to use the Ajax.Autocompleter control. The problem is that Ajax.Autocompleter only responds to onkeypress events made with a real keyboard, but my on-screen-keyboard causes onchange events when a letter is clicked and appended to the input field. So, is there a way to

hi all, my problem: i have a form that is sent through ajax with ajax.updater. the onsubmit function looks like this: new Ajax.Updater( { failure:''command_div'' }, ''/windows/chat_post'', { asynchronous:true, parameters:Form.serialize(this } ); return false; this works fine when I submit the form by pressing the submit button.

Hi list, i spent the last two days building a window class. Windows can be dragged, resized, minimized and closed. The windows are table-less, which makes rendering faster. Also divs with overflow:auto don''t seem to like dragging. The class is losely based on the resizable class by Michael Daines, which was posted here some weeks ago. BTW i spent three times more time on CSS tweaking

Hi all, I work with a CUPS/Samba Printserver and I allocate the drivers via the point n print methode. Yesterday I get a new HP Laserjet 2420. I installed the HP-driver with the APW of Windows XP. Everything seams to be ok. I printed a testpage without any problems. In the next step I tested the new options of this printer (duplex,...). But I saw, that the driver did not offer this options. I

Hi, is it possible and safe to use more than one RAC-Cluster using OCFS in the same LAN? I'm considering to following setup: a 2-node production and a 2-node test system, the production data is stored in an EMC Symmetrix and for the test-system the production data is copied once to a BCV disk internally. This will give me an new independant copy of the production disk with the same contents,

Hi Folks, just updated my current Dialplan available on http://capi4linux.thepenguin.de/download/asterisk/config/ It now heavily uses ODBC database (MySQL) to hold most of the data like extensions and incoming connection numbers. An example databasefile is also included. The denylist has also been updated for future and current settings of the german telecom regulator. Again I added many

Hi group, I have problems with a former Samba-server. It has been a simple server, no acl-stuff,not a DC or so. Now we have a Windows 2003 PDC and I intergated the Samba-Server as a Domain Member Server. Everything works fine, except one annoying thing: I cannot allow the Domain-Members to full-access the files recursively. Example: The users complain, that they can make an excel-sheet and

Hello, I am configuring samba the first time as PDC so that a user can login on different pcs with the same password. To do this, I have configured smb.conf as follows. I'd appreciate, if someone could see, if the file is complete to run samba as a PDC. [global] workgroup = windowsGroupname netbios name = ComputerName server string = Samba Server %v interfaces = lo, eth0 unis password

Hi, I would like to know if there's a way to detect the workgroup of my own server with libsmbclient. With earlier versions than 3.0.20 it was possible to use smbctx->workgroup after the context was initialized. Since 3.0.15pre2 or so its always "WORKGROUP". Am I missing something?

hi all, I run a Suse 9.3 with Samba 3.013. If a User opens a file which another User has already opened M$ Office reports that the User who saved the file the last time has locked the file, not the actual User, who holds it open. My Sambaserver is a Domain Member of a W2k Domain. Any suggestions? Thanks in advance, Bjorn Schweizer ______________________________________________________________

Hi, I'm using Samba 3.0 as a PDC on SuSE Linux 9.1. I want to add a samba user using the command "net user add <username> <password>". But always when I use this command I receive the message that I have to specify the user. But according to the man page that is the way how to do it... Has anyone experiences with this command? Until a few days ago I used smbpasswd -a
