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.

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 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

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

Dear All, Are there any existing scripts to plot Taylor Diagram (definition see http://www.ipsl.jussieu.fr/~jmesce/Taylor_diagram/taylor_diagram_definition.html ) ? Thanks a lot! Linda [[alternative HTML version deleted]]

Hello there, any ideas on how to save all the objects on my workspace inside a list object? For example, say my workspace is as follows ls() [1] "x" "y" "z" and suppose I want to put these objects inside a list object, say object.list <- list() without having to explicitly write down their names as in object.list$x = x object.list$y = y object.list$z = z Is

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 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, I'm looking for software that can perform kriging on systems with dimensionality higher than 3, say d=5. Are anyone aware of packages in R that can do this?

Hi, I am not sure to get the issue, but assuming your data are arranged as in your example with dates in column x$V1 and signals as x$V2 , I think that you could use "rle" in the following way : test<-rle(x$V2) testmat<-matrix(NA,length(test$values),2) testmat[,1]<-x[c(1,cumsum(test$length)[1:(length(test$values)-1)]+1),1] testmat[,2]<-test$values And you'll get your

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

Hi list, I thought I was used to layouts, but today I am facing a problem I cannot overcome : On my R installation (Windows 7 Pro, SP1, R version 2.13.0, daily update of packages), I am not able to put raster plots in user defined layouts : > layout.matrix<-matrix(c(1,2,3,4,5,5),2,3) > layout(mat=layout.matrix) > layout.show(5) works fine, I get the correct frames in

Hi listeRs, Maybe I have missed something, but I am facing a problem I don't understand even after reading archives and manuals (…maybe not carefully enough !) : On my PC (64-bit OS, Intel Xeon CPU , two L5506@2.13 GHz processors, 12 Go RAM) under Windows 7 SP1, I run both 32-bit (i386-pc-mingw32/i386) and 64-bit (x86_64-pc-mingw32/x64) version 2.14.2 (2012-02-29) of R, packages

Hello to everybody, ... and sorry if the question has already been answered. I am dealing with complex numbers and need a way of plotting them on angular plots (2D and 3D). Is there a package that already manage this, or can somebody in this R-world who could help me with his skill ? Thanks to all. Have a nice week-end !

The scagnostics package implements the graph theoretic scagnostics described by Leland Wilkinson, Anushka Anand and Robert Grossman (http://www.ncdm.uic.edu/publications/files/proc-094.pdf), building on an old idea of Tukey's to define indices of "interestingness" to help guide the search for interesting features in the pair-wise scatterplots of a highly multivariate dataset. The

Dear R-gurus, being very new to R, (as well as lazy and not too smart !) I have some problems (and get lost in the docs) trying to write something to find the 9 values (A1,B1,C1,A2,B2,C2....C3) which are solutions of a 12 equations system of the form : > x1-(A1/(A1+B1+C1)) = 0 > y1-(B1/(A1+B1+C1))= 0 > z1-(C1/(A1+B1+C1)) = 0 > 3 same equations with subscript 2 > 3 same

Hi again, this is a follow-up of my previous post : I've noticed that > attr(first.list[[1]]$size.ecdf,"call") gives ecdf(test.moms[, "m.pxs"]) and that there is no "test.moms" field in my records (a local variable named test.moms was used inside a function, but it was stored under another name in the list, outside the function) May this be the answer (and

Dear Everyone, I wrote a Taylor diagram program in R, but it was not very general, so I was happy to find the Taylor.diagram in the plotrix package. On the other hand I can find many problems with the pos.cor=TRUE case, in other words, when we use only the first quarter of the space (positive correlations). (When we choose pos.cor=FALSE, the program seems to me perfect) 1.There is only one line
