The integral of any probability density from -Inf to Inf should equal 1, correct? I don't understand last result below. > integrate(function(x) dnorm(x, 0,1), -Inf, Inf) 1 with absolute error < 9.4e-05 > integrate(function(x) dnorm(x, 100,10), -Inf, Inf) 1 with absolute error < 0.00012 > integrate(function(x) dnorm(x, 500,50), -Inf, Inf) 8.410947e-11 with absolute error <

Dear R developers, ?help.search ...opens a tab in my browser (Firefox 3.5.6, Win XP): http://127.0.0.1:31642/library/utils/html/help.search.html When I click on the link for "?", (http://127.0.0.1:31642/library/utils/help/?) in the last line of "Details", I get an error message: "Server error: invalid response from R".

Greetings and happy new year! I am in the process of converting some of the old S-PLUS scripts from Visualizing Data (Cleveland, 1993) into lattice. In fact, I did most of it several years ago, and at the time, all of the scripts that contained loess() worked fine. Tonight, I ran most of the scripts again, but every one that I tried with a loess() call crashed R. I tried it in two sessions, one

Hi, I would have thought that these two constructions would produce the same result but they do not. Resp <- rbinom(10, 1, 0.5) Stim <- rep(0:1, 5) mm <- model.matrix(~ Stim) Xb <- mm %*% c(0, 1) ifelse(Resp, log(pnorm(Xb)), log(1 - pnorm(Xb))) pnorm(as.vector(Xb), lower.tail = Resp, log.p = TRUE) > ifelse(Resp, log(pnorm(Xb)), log(1 - pnorm(Xb))) [1] -0.6931472 -1.8410216

Hi, consider the following > a<-gl(3,3,9) > a [1] 1 1 1 2 2 2 3 3 3 Levels: 1 2 3 > levels(a)<-3:1 > a [1] 3 3 3 2 2 2 1 1 1 Levels: 3 2 1 > a<-gl(3,3,9) > factor(a,levels=3:1) [1] 1 1 1 2 2 2 3 3 3 Levels: 3 2 1 It is probably something obvious I missed, but reading the documentation of factor, and levels I would have thought that both should produce the same output as

Dear R developers, I find the format of descriptions of the arguments in the read.table help text slightly inconsistent. For example, the logical arguments comes in seven different formats, more or less explicit about the consequences of a TRUE (or FALSE): 1. check.names logical. If TRUE then the names... 2. blank.lines.skip logical: if TRUE blank lines... 3. flush logical: if TRUE,

Trying to install World of Warcraft on ubuntu 8.10, with the most recent version of wine, and I get to the end user license agreement, scroll all the way down, and I can't click agree on it to continue with installation. I'm using the download game client feature from my account on WorldofWarcraft.com, not the game CD's because I have a broken CD drive. If that helps any.

I am admittedly very computer stupid. However, I do have wine installed and I have downloaded the World of Warcraft package to install. When I double click on the wowinstall icon, it pulls up wine, no problem. I select the WotLK program (have also tried just plain WoW and BC), select install, select English, select OK. I scroll to the bottom of the terms of use and the "Agree" button

I appear to have lost the whole of my home directory on my centos server (which includes all my mail saved from the last 7 years). Although I have recent backups of most data I would like to copy important files from /etc, and, if possible, /var/logs so that I can try to find out what went wrong. However, knoppix refuses to let me write to either my usb hdd or usb pendrive. Does anyone know how

Greetings all. I am attempting to install dom-u guests on a vanilla install of Centos 5.6. I am attempting to use the Xen Manager and it 1) won't let me choose ANYTHING but network install, which is quite odd to say the least, and 2) won't let my freebsd install iso complete. I am a novice with Xen, however, it doesn't make sense even in the most minimally supported system that

(Apologies if this has already gone to the list. I've been trying to post via the newsgroup and it appears none of my messages went through...so now I'm doing it via the list-serv) I have samba (2.28) running on a linux server (Mandrake 9.2). Neither my win2k machine nor my OSX (panther) machine will see the share via the network browser. In my OSX machine, I CAN connect if I

Hi, We have an old Win98 box at work that is used for programming GALs and EEPROMs, however we find that if the file is modified on the Unix side the Win98 box doesn't notice. This is rather annoying when you are iterating a design as you can imagine! One work around is to open a DOS box and 'type' the file - this seems to force it to re-get the file. Does anyone have any

Hello I'm running Samba 3.6.6 on an ARM Debian appliance. While I can successfully copy files from a Windows 7 host to Samba, Windows won't let me delete files on the Samba host: "File cannot be deleted. Please remove the write protection." Performing this operation as Administrator makes no difference, and no information is reported in /var/log/samba/log.smbd. Here's my

The example at ?pictex does not work (the driver apparently uses 'rotatebox') for me as stated. It did compile after including the graphicsx package. A MWE is at the help page for pictex. I tried to get in touch with Valerio but his email bounced. Probably we want to add a \usepackage{graphicsx} to the help page and try to track down Valerio. Cheers, Kyle This is pdfTeX, Version
