Folks, I have a dataframe comprising a column of dates and a column of signals (-1, 0, 1) that looks something like this: 30/01/2007 0 31/01/2007 -1 01/02/2007 -1 02/02/2007 -1 03/02/2007 1 04/02/2007 1 05/02/2007 1 06/02/2007 1 07/02/2007 1 08/02/2007 1 09/02/2007 0 10/02/2007 0 11/02/2007 0 12/02/2007 1 13/02/2007 1 14/02/2007 1 15/02/2007 0 16/02/2007 0 What I need to do is for each signal

Hi R-listers, I run R version 2.13.0, on a i386-pc-mingw32/i386 platform under Windows XP. I perform daily update of my installed packages. I've got the most recent Java for this platform installed, as I am told by the JavaUpdater when checking. (and I've read the posting guide, so that I'm not going to get fired by Uwe as poor wwreith [joke])... But : since one of the last daily

Hi Hadley, thank you for providing this "scagnostics" primer.... I was trying to do some basic testing, and I see that I probably missed some points : first it's not clear for me if the argument of "scagnostics" should be raw data or "processed" data (results of calling "splom" or whatever...). If the first, I thought (from Wilkinson & al.) that if

Sorry if this answer was already given, or if I miss the point, but did you have a look to "lowerTriangle" and "upperTriangle" functions in the "gdata" package ? # example # A<-matrix(rnorm(9),3,3) # B<-B<-matrix(NA,dim(A)[1],dim(A)[2]) # lowerTriangle(B)<-lowerTriangle(A) # upperTriangle(B)<-lowerTriangle(A) # diag(B)<-diag(A) Hope this helps,

Dear list, (sorry if I post to the wrong place...), Though having spent some time on it, I cannot find an answer by myself to the following behaviour of the read.image function (adimpro package) : I'm running R.2.6.2 on Windows XP. The home directory is C:\Program files\R\R-2.6.2 Version 0.4.4 of adimpro is loaded. ImageMagick 6.3.0 is installed, its directory is C:\Program

Hello eveRybody (and probably special regards to Gabor G....), I recently upgraded from R-2.9.2-win32 to R-10.1.0-win32, and I'm using Windows XP Professional 2002 with service pack 3 on a PC with IntelCore Duo CPU@ 3.00 GHz. Last time I used it (some weeks ago, before upgrading), one of my scripts (including the two lines cited below) used to run OK. When I ran it yesterday evening (after

Hi again, Awfully sorry John, I should have been sleeping and did not see your full post.... here is a way, unless I miss the point again : fake<-as.data.frame(cbind(seq(1,10,by=1),c(rep(1,4),rep(0,4),rep(2,2)))) # from my previous post # one moree column this time ! fake3<-cbind(fake,fake$V2) index<-c(2,3) fake3[,index][fake3[,index]==0]<-NA not nice, but seems to do the job.

Hi John, Unless I miss a point, why dont you try something like : # some fake data > fake<-as.data.frame(cbind(seq(1,10,by=1),c(rep(1,4),rep(0,4),rep(2,2)))) V1 V2 1 1 1 2 2 1 3 3 1 4 4 1 5 5 0 6 6 0 7 7 0 8 8 0 9 9 2 10 10 2 # change 0 by NA > fake[fake==0]<-NA # or fake$V2[fake$V2==0]<-NA if you

Hi list, My attention was drawn to the foreach package by recent posts...I decided to have a look... I'm using R.2.9.1 on Windows, I have downloaded the foreach package today (v 1.2.1), together with iterators (v. 1.0.1) and codetools (v.0.2-2). Full of hope I try the most simple thing of all out of the package vignette : > x <- foreach(i = 1:3) %do% sqrt(i) and get : > Erreur

Hello, list why not add the smart proposal by Greg Snow as a built-in function in {stats}, just changing the "x234" and "newc" lines to allow for more distributions to be generated ? Or do I miss an already existing function to do that ? Regards. Olivier # slight modification of the original code by Greg Snow [mailto:Greg.Snow at intermountainmail.org] # on April 04, 2007

Dear List.... sorry to bother you R-gurus with such an "unstatistical" question... but I face a problem using Crimson Editor with R 2.01.1 that I never had using R 2.00.1. I already posted on the Crimson Editor forum but it seems to be VERY few R-users there.... I successfully used R v2.00.1until now (under Windows XP professionnal, version 2002, Service Pack 2, P4 processor CPU 1.8

With rw2010dev I get a strange protect(): protection stack overflow error with a small data frame which otherwise is usable: If anybody wants to have a look I can provide an RData file with the problematic data frame. Doesn't seem to be necessary, the following simulated example generates the error: > testmat <- matrix(1:80, 20,4) > dim(testmat) [1] 20 4 > str(testmat) int

Hello All, I'm trying to run a maximum likelihood analysis using dmultinomial (i'm avoiding dmultinom as I'd like to run it with vectors for the ML stuff). However, I'm having a hard time getting even the simplest example running. Any help would be greatly appreciated. > library(mc2d) > dmultinomial(x=c(0,0,1),prob=c(1,1,1),size=1,log=TRUE) Error in if (ncol(x) != K)

Hi, The Matrix package and the as.matrix method do not seem to be compatible inside of a package. Here's an example. I've created a simple package "mat" that defines an eponymous class and as.matrix method on that class. All is well, unless that package has the Matrix package in its Depends or Imports (and imports, e.g. the "Diagonal" function). Then my as.matrix

Georgi, Brilliant, thank you very much for the helpful reply and explanation! I added 'importFrom("Matrix","as.matrix")' to my NAMESPACE and all worked fine! As my 'as.matrix' method is used entirely internally to the 'testmat' function (and not "used outside the package"), I don't think I actually need to export it. In my case, testmat is

Hi, Short answer: import 'as.matrix' and export your method(s) for it. From WRE: "All S4 classes to be used outside the package need to be listed in an exportClasses directive. Alternatively, they can be specified using exportClassPattern.(46) in the same style as for exportPattern. To export methods for generics from other packages an exportMethods directive can be used."

Resolved this morning, the issue is that the qemu-kvm-ev rpm's released by centos have not been compiled with curl support, I rebuild it myself from source with curl support and it works fine now. Thanks you for your input everyone. ________________________________ From: Vasiliy Tolstov <v.tolstov@selfip.ru> Sent: 09 August 2018 10:32:07 To: Inception Hosting Cc:

Avent Coupons can go a long way in improve the quality of your child?s well being. The best way to look out for these coupons is on internet. But that does not mean it is the only way. These are available in America?s finest magazines about parenting and child upbringing. But still there is no denying that fact that 75% of Americans search through the internet before making any purchases.

Did you have a backup of your information? My upbringing and was tought to have backups of backups. In case of emergencies. Your situation is not different your a very good admin but always keep backups. My advice is try to find matching components and see if that fires up your server to get it going. Then if it starts to work. If not. ...... Your up a creek. Sent from my T-Mobile 4G LTE device
