hi all, I want to get a cumsum according to the order of some variable. However, it doesnt' work. For example, ********************** test<-data.frame(cbind(x=c(3,5,2,6,7),y=c(8,1,4,9,0))) test[order(test$x),]$sumy<-cumsum(test[order(test$x),]$y) ********************** R complians Warning message: In `[<-.data.frame`(`*tmp*`, order(test$x), , value = list(x = c(2, : provided 3 variables to replace 2 variables. while the following *********************** test$sumy<-cumsum(test[order(test$x),]$y) *...

dear giovanni--- thanks for answering on r-help to me as well as privately. I very much appreciate your responding. I read the plm vignette. I don't have the book, so I can't consult it. :-(. I am going to post this message now (rather than just email it privately), because other amateurs may have similar questions in the future, and find this message and your answers via google.

Hi I am a beginner with R. I have been trying to import a tab delimited excel file but i get the following error message > file.show('C:\Documents and Settings\stats\Desktop\SUMI\plasma2.txt') Warning message: file.show(): file 'C:Documents and SettingsstatsDesktopSUMIplasma2.txt' does not exist I have understood the programming part but i cannot go ahead unless i have

Dear all I have a function in which I would like to change some values to NA according to some condition. dropout<-function(y, nahr=FALSE,...) { <some stuff for computing an index> if (nahr) y[index]<<-NA invisible(index) } in case y is a vector all works OK but if it is a part of data frame by calling dropout(df$y) or dropout(df[,number]) no change is done. Please can you

Hi, Optimizes celt_pitch_xcorr for floating point. Changes from RFCv1: - Rebased on top of commit aad281878: Fix celt_pitch_xcorr_c signature. which got rid of ugly code around CELT_PITCH_XCORR_IMPL passing of "arch" parameter. - Unified with --enable-intrinsics used by x86 - Modified algorithm to be more in-line with algorithm in celt_pitch_xcorr_arm.s Viswanath Puttagunta

Hello, I am trying to use 'R' for K-means simulatio, could you please advise me how I can read my data into a two dimesional array? Or is there any method which directly reads the excell file? Please let me know asap. Regards Skanda Kallur Cogito, Ergo Sum! Rene Descartes

Dear all, I have 9 data frames, and I'm simply trying to sum the values of column 3 (on a row-by-row basis). However, there are a slightly different number of rows in each data frame, so I'm receiving the following error: "Error in Ops.data.frame(mrunoff_207101[3], mrunoff_207102[3]) : ? + only defined for equally-sized data frames". Here is what I'm attempting to do:

...cate counts at each site N=rpois(n = n.site, lambda = lam) #True abundance # Simulate count data; only a fraction of N is counted which results in y y <- array(dim = c(R, T)) for(i in 1:T){ y[,i] <- rbinom(n = n.site, size = N, prob = 0.5) } #truncate y matrix y # R-by-T matrix of counts sumy=apply(y,1,sum) cbindysumy=cbind(y,sumy) subsetcbindysumy=subset(cbindysumy,sumy!=0) y=subsetcbindysumy[,1:3]# sites where no animals ever counted are removed C1<-c(y) #vectorized matrix y R=dim(y)[1] site = 1:R site.p <- rep(site, T) #########################################################...

Optimize celt_pitch_xcorr function (for floating point) using ARM NEON intrinsics for SoCs that have NEON VFP unit. To enable this optimization, use --enable-intrinsics configure option. Compile time and runtime checks are also supported to make sure this optimization is only enabled when the compiler supports neon intrinsics. --- Makefile.am | 11 ++

Okay, I have a server connected to the net but have not added fail2ban or anything on top of my firewall yet. Thought you guys might get a kick out of this one user, ip is from china, who has got a heck of a knack for making assumptions on possible usernames. Enjoy this..., 8000+ attempts. Scroll down for funky ones. I have no root access enabled on this server and it is pretty bare. Just using

Dear all, We have samba-3.0.11 on freebsd 5.4 as file/print server it works perfect, but if two users open the same file together the second still can write to the file it cannot be allowed in you situation. But the other server with freebsd 4.11 doesn't have this problem perfectly do write lock on open file, so may be it's freebsd 5.x problem? I can't find what's wrong,

Hi list, I was wondering is it possible for third part apps to force LEVEL_II oplocks? We have designer office with autocad 2004 which doesn't do level2 oplocks, but M$ Word do all the time. It seems that M$ Word create lock file like name.ext => ~$me.ext but autcad create name.dwg => name.dwl lock file. Thanks. -butsyk
