Dear all, I'm trying to combine in R the two following datasets. I'm would be very grateful if someone could help me with this problem. Dataset 1: X Y Z 1 27 48 2 25 50 3 27 40 4 28 56 Where X is a unique number and Y and Z some variables Dataset 2: X I J 1 10 12 1 12 12 1 23 30 1 40 46 2 7 8 2 8 9 2 9 8 3 2 0 4 98 87 4 78 89 Where X IS NOT this time a unique number. I and J are some

[Version fran??aise plus bas] To the R community, A quick word to announce the publication of my document "Introduction ?? la programmation en S". It is available in the French section of the Contributed Documentation page of CRAN. Many of the documents or books currently available on S-Plus and/or R present the software in a statistical analysis context. My document rather focuses

Dear R developers, I'm a former APL programmer. In that language, the "take" (up arrow) and "drop" (down arrow) operators were extensively used to, well, take and drop elements of vectors. Functions head() and tail() are equivalents in R for the "take" operator, but nothing seems to mimic the "drop" operator. I think it would be useful. For

Is there a canonical way to check if all elements of a vector or matrix are the same? Solutions below work, but look hackish to me. > x <- rep(1, 10) > all(x == x[1]) # == operator does not provide for small differences [1] TRUE > isTRUE(all.equal(x, rep(x[1], length(x)))) # ugly [1] TRUE Best, Vincent -- Vincent Goulet, Associate Professor ??cole d'actuariat

Hello Garming, In the link above (sorry, it's in French), I can read how to downgrade a feature level of a 2012-R2 domain to work in 2008 R2. https://sloze.wordpress.com/2014/06/18/active-directory-diminuer-le-niveau-fonctionnel-dune-foret-etou-dun-domaine-2/ Here is the English version of the Set-ADDomainMode command: https://technet.microsoft.com/fr-fr/library/hh852281(v=wps.630).aspx

Hi all, Is there an option in Sweave to avoid it from stopping on a code chunk with an error? (I purposefully want to include code with an error in class notes.) I suspect the answer is "no" and that I will be pointed to options("error"). That'd be fine, but which error parameter will just "do nothing" in case of an error? Thanks in advance! -- Vincent

Dear all, I ran the following model without any problem previously to the update of lme4: fm2<-lmer(data=NGud,family=poisson, seed~hab*seedtray +(1|site)+(1|site:hab)) I have 25 sites, 2 habitats ("hab") per site, 8 seedtrays per habitat (4 as control, and 4 as treatment), and I'm interested in comparing the number of seed in seedtrays as a function of the treatment and its

Hi, Is it possible to remove the points at the base of a density plot?I would like to keep only the curves of the plot, not the points. Thank you. Marie-Helene HacheyM.Sc. studentUniversite Laval, Quebec

I have a weird issue when I wanna see Security Tab in the file property's. I dont see the user and group name's but only their SID. See pictures but when I add users and group acl on this file, I get their user and group name. If I close and reopen the propetu of this file, I get again the SID Someone know how to fix this issue?? My file server is a domain member of the PDC My PDC

I created a type of object similar to a data frame. In some circumstances, It needs special methods for "[" and "[<-" and rbind() (but not cbind()). Then I found this in the cbind()/rbind() man page: The method dispatching is _not_ done via 'UseMethod()', but by C-internal dispatching. Therefore, there is no need for, e.g., 'rbind.default'.

Package grDevices has a function cm() to convert from inches to centimeters. Its definition is: cm <- function(x) 2.54*x As far as I can tell, the function is not used anywhere in the R sources (I grepped for "cm(", "cm)" and ", cm".) I did not check for all packages on CRAN, though. May I propose to remove this apparently useless function from the sources? [I

In trying to change the driver used by Sweave on the command line using R CMD Sweave --driver=foo I consistently get the "directory 'foo' does not exist' error. (For any value of 'foo', even the default 'RweaveLatex'.) Looking up the source code for function .Sweave that is called by 'R CMD Sweave', I notice that the argument 'driver', if

Dear developeRs, Compilation of the latest version (0.9-5) of my actuar package fails with r-release MacOS_X ix86 on CRAN; see http://www.R-project.org/nosvn/R.check/r-release-macosx-ix86/actuar-00check.html All errors come from accented letters in comments in latin-1 encoded files (except hierarc.R which is in UTF-8, my bad). Encoding is declared as latin-1 in DESCRIPTION. The package

A big thank you to everyone who attended the CentOS Dojo in Brussels a week ago. We had about 75 people in attendance (101 registered) and we had two tracks of great presentations. If you did not make it to the event, you can still catch all of the presentations on our YouTube channel, at https://www.youtube.com/user/TheCentOSProject/playlists Unfortunately, you miss out on the great

I have a samba server on linux with a LDAP DC, On a client server, I was do net join -S DOMSERV -Uadmin%PASSWORD and that's work The server member of DOMSERV have a share XFS filesystem. When I set manualy the acl (setfacl -m g:group:rwx the_file) It's ok, the other domain member see the ACL But when I set the acl with a Windows Workstation, that's don't work

Dear all, I'm doing univariate Poisson regressions using the "glm" and "glm.fit" functions. I have 5 independent datasets and each dataset, has one response variable and more than 20 factors to test. Currently, I run one regression at a time and manually take notes of the results in excel to have a quick overview on what is going on in my data. My poor method is very

Dear alls, Could someone tell me how to select a subset of string observations (e.g. "females" in a sex column) with sqlQuery in the RODBC library? Indeed, I'm trying to select a subset of observations on my access database with: female<-sqlQuery(mychannel,"SELECT Micromammiferes.sex FROM Micromammiferes WHERE (((Micromammiferes.sex)="females"));") The sql

Hi, I need to do several matrix multiplications with the corresponding matrices forming two 3-dimentional arrays. To illustrate my problem, let's say I have the following 3-dimensional arrays: array1 <- array(1:30,dim=c(3,2,5)) array2 <- array(1:20,dim=c(2,2,5)) I know that I can get what I want with the following computation : result <- array(dim=c(dim(array1)[1],
