Dear userR, With the following results, are they correct or acceptable? > x <- c(1.4, 1.2, 2.8) > sum(x) [1] 5.4 > sum(x) == 5.4 [1] FALSE > (1.4 + 1.2 + 2.8) - 5.4 [1] -8.881784e-16 > (1.4 + 1.2) - 2.6 [1] -4.440892e-16 > 2.6 - 1.5 - 1.1 [1] 0 > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor

dear userR: I am trying to plot two dependent variables in the same plot in ggplot2. because these two variables have very different magnitude, I have to use a second Y axis. I hope one variable to be line and the other to be barchart. The x axis is continuous. Yet since I have to make barchart, I guess I have to treat it as discrete or categorical. I have been google searching for the whole

Que tal Miguel.Bueno, este es un buen intento para los programas que manejan el denominado "Flujo de conocimiento", que lo que tratan es de ordenar los pasos que intervienen en un proceso (proceso=análisis, reporte, etc.) y la ayuda que brindan los softwares, es que los objetos ya definidos para las distintas tareas.Hay algunos de estos programas: Enterprice guide y miner de SAS,

I've just committed a couple of changes to R-devel related to requests at userR about the Windows installer. The first of these affects all platforms, but I've only tested it on Windows: I added an option "quit.with.no.save". If TRUE, then the default q("ask") prompt will not offer to save the workspace. This is in response to the observation that new users who

Looking over the contents of various packages, including my own, it is clear that lots of things end up 'hidden away' in packages where they don't belong. My gregmisc package is a particularly egregious example, containing something from almost every functional category. I propose that from time to time the R community go through the complete set of packages and 'refactor'

Having set up two way trust between a Samba domain (with LDAP backend) and an AD domain, I find that 1. Users from the trusted domain are authenticated against the proper DC (that is, their regular password works), but only if there is a corresponding local domain user. 2. Users from the trusted domain are being mapped onto Samba/POSIX users associated with the local Samba domain, despite

I have four large two-dimensional matrices of which I want to create contour plots. Something like filled.contour(<matrix>) contourplot(<matrix>) works but only gives me one plot at a time. If I combine the four matrices into one three-dimensional matrix, which I'll name "seven", there should be a way of doing something like this contourplot(seven[,,k] for k in 1 to 4)

One of the recurring themes in the recent UserR conference was that many people find it difficult to find the functions they need for a particular task. Sandy Weisberg suggested a small idea he would like to see: a hints function that given an object, lists likely operations. I've done my best to implement this function using the tools currently available in R, and my code is included at the

So I'm trying to track an special value in IPA instruction generation. https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gm107.cpp#L2561 Register on 0x14 (20) is set to some source on "insn->op == OP_PINTERP" I have found while emulation that such value can be set sometimes to FragCoord.w, I don't however know what that value is and

Hi, I?m trying to figure out how to practically use RADIUS to authenticate users. So far, I have only found documentation explaining that the idea is that users somehow magically need to authenticate against a RADIUS server via a device like a switch or a wireless access point before they are given or being denied access to a network. I understand that I have to refer to the documentation of

Hello, I have a x,y,z file.Z is not corresponding to a simple analytical function of x and y (see below). I am trying to find the minimum location of this surface and the z value corresponding to this location by a spline interpolation or from a polynomial fit. I tried with the akima package but as the location of the point I am looking for (the minimum) is outside of the convex hull it's

In the next version of the survival package I intend to make a non-upwardly compatable change to the survfit object.? With over 600 dependent packages this is not something to take lightly, and I am currently undecided about the best way to go about it.? I'm looking for advice. The change: 20+ years ago I had decided not to include the initial x=0,y=1 data point in the survfit object

I have 3 vectors: p1, p2, and p3. I would like each vector to be any possible value between 0 and 1 and p1 + p2 + p3 = 1. I want to graph these and I've thought about using scatterplot3d(). Here's what I have so far. library(scatterplot3d) p1 <- c(1,0,0,.5,.5,0,.5,.25,.25,.34,.33,.33,.8,.1,.1,.9,.05,.05) p2 <- c(0,1,0,.5,0,.5,.25,.5,.25,.33,.34,.33,.1,.8,.1,.05,.9,.05) p3 <-

Hi, Radius is a AAA protocol (Authorization, Aurhentication and Accounting) you can use rhe three methods or only one of them. Authentication can be done by usong a Freeradius Server, aitvorization will give a userr profile with certain privileges for example In a network connection, and accounting (user connection details) can be registered In a MySQL database if needed.

Hi All, Over the weekend I bit the bullet and migrated my entire office from server to another and converted everything from MBOX to Maildir. Althought it took ages and their we're a few little problems along the way, the migration was a complete success with no users reporting any problems(Mbox used to always cause file lock ups) or even noticing anything had changed... Which is

We have been asked for a couple of years about builds of R for 64-bit Windows, e.g. at UserR 2006. Users of 64-bit Windows still seem very thin on the ground, but apparently 'Microsoft scraps 32-bit operating systems Microsoft has announced that Windows Server 2008 will be the last 32-bit system it releases, for servers or clients, as it makes its way fully into the world of

Dear userRs, when applied the summary function to a glm fit (e.g Poisson) the parameter table provides the categorical variables assuming that the first level estimate (in alphabetical order) is 0. What is the standard error for that variable then? Are the standard errors calculated assuming a normal distribution? Many thanks, -- View this message in context:
