Is this correct?
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-...

Standard errors GLM
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 di...

how to put barchart and line chart in the same plot in ggplot2
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 hav...

Dear UserRs, I draw filled contour plot with filled.contour function. By default, colors of filled.contour is terrain.colors which alters from green (the lowest level) to white (the highest level). I want the colors to alter from white (the lowest level) to green (the highest level). How can I set this...

Availability of quadplot3d package (UseR!2006 Four Dimensional Barycentric Plots in 3D)
Dear List, I have been unable fo find the package quadplot3d referred in the Abstract/Presentation "Four Dimensional Barycentric Plot in 3D" presented in the UserR!2006. Does anyone know if it is available ? And if so, if it is ported to Windows ? Thanks in anticipation, Carlos Ortega [[alternative HTML version deleted]]

Passing a missing argument
Dear userRs, Is there a way to explicitly set an argument to a function call as missing? E.g., histogram(foo, bar, endpoints=ifelse(!missing(limits),limits,NA/NULL/whatever))) In this call I want to set a value to the endpoints argument only if the `limits' variable has been set, a...

ggplot2 - expand range?
Dear UserRs, I am trying to use systematically ggplot2 for most of my plots, but I am fighting some lack of documentation, which I try to overcome. I want to build a scatterplot where the axes cross exactly at (0,0). I tried using scale_y_continuous(limits=c(0,10)), but I always get an extra space at the...

Converting strings with internal delimiters into lists
Hi UserRs, I know that there has to be an easy way to do this in R (probably easy enough that once someone clues me in I'll smack myself on the forehead for not figuring it out myself), but my searches on my own have not yielded any hints. I have many fields in my dataset that participants entered as...

Proposal: 'global' package refactoring
...could be easily categorized, but I believe that this effort would yield significant benefit and is compatible with the goal of R-core to streamline the base packages. To put my money where my mouth is, I'll volunteer to organize a group effort to do such a refactoring in conjunction with the userR! 2004 or the next DSC, whichever folks agree is better for this purpose.

GLM and Neg. Binomial models
Hi userRs! I am trying to fit some GLM-poisson and neg.binomial. The neg. Binomial model is to account for over-dispersion. When I fit the poisson model i get: (Dispersion parameter for poisson family taken to be 1) However, if I estimate the dispersion coefficient by means of: sum(residuals(fit,type=&q...

Evaluation "conflict" in combination of replicate() and rexp()as variable inside a function
Dear userRs, "playing around" with combinations of replicate() and random number generating functions inside a self-defined "wrapper" function I encounterd a puzzling behaviour. The following are intentionally simple (and rather nonsense-) examples to isolate the relevant aspects. Ple...

options("quit.with.no.save"), and Windows installer changes
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 tha...

RADIUS
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

Trusted domain users unwantedly mapping onto local domain users
...ame. * The idmap OU in the directory now has two dozen entries (the AD domain is only used for one specialist part of the company). So far so good. "getent group" and "getent passwd" shows the TRUSTED domain users have been added and are visible as POSIX users. TRUSTED userr can authenticate to any OFFICE member servers using their own passwords (with the important caveat mentioned abouve). At this point, I'm at something of a loss. I can ssh into the domain controller as TRUSTED\test.user, whether or not there is a corresponding user in the local domain, and the...

RADIUS
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. Check for guodes con how to install and use Freeradiua on CentOS. Regards, El mi?rcoles, 14 de febrero de 2018, hw <hw at gc-24.de&g...
