My question is really to Robert and Ross (and also to Bill Venables and Dave Smith) -- but I thought that there might be wider interest in it. The "Notes on R" in the file Rnotes.tgz is copyrighted to the above authors -- can I make copies of it to distribute? I suspect that the intention of the authors is that Rnotes be as re-distributable as R itself. However there is no GNU license

Dear R users, how do I e.g. square each second element of a vector with an even number of elements? Or more generally to apply a function to every 'nth' element of a vector. I looked into the apply functions, but found no hint. For example: v <- c(1, 2, 3, 4) mysquare <- function (x) { return (x*x) } w <- applyfun(v, mysquare, 2) then w should be c(1, 4, 3, 16) Thanks for

Dear R users, Given this data: x <- seq(1,100,1) dx <- as.POSIXct(x*900, origin="2007-06-01 00:00:00") dfx <- data.frame(dx) Now to play around for example: subset(dfx, dx > as.POSIXct("2007-06-01 16:00:00")) Ok. Now for some reason I want to extract the datapoints between hours 10:00:00 and 14:00:00, so I thought well: subset(dfx, dx >

Hello, Two lapply questions (system info and sample data below): 1) Why does the first form of command1 add the name of y _after_ the str() output rather than before as does the second (preferred) form? # command1 version1 invisible(lapply(ls(pattern='bn'), function(y) cat(y, "\n", str(get(y)), "\n") )) # command1 version2 (preferred output)

Hello, I am member of research team on our Faculty of Information Technology (university VUT in Brno Czech Republic). We use LLVM for many projects and actually we want to create system, which will be able compile and profile aplication for VLIW processors in few iterations. We want to load profile information in 'opt' part of LLVM and use it for create superblocks. Note, when

Hi r-users,   I would like to extract the data that match.  Attached is my data: I'm interested in matchind the value in column 'intg' with value in column 'rand_no' > cbind(z=z,intg=dd,rand_no = rr)             z  intg rand_no    [1,]  0.00 0.000   0.001    [2,]  0.01 0.000   0.002    [3,]  0.02 0.000   0.002    [4,]  0.03 0.000   0.003    [5,]  0.04 0.000   0.003    [6,] 

Dear R Users, Lets assume I have this data frame: x y z 1 1.00 5 0.5 2 1.02 5 0.7 3 1.04 7 0.1 4 1.06 9 0.4 x and y columns are sorted and the values not necessarily integers. z values are not sorted. Now I would like to create a matrix out of this with x as first column values and y as first row values. Matrix element a_11 shall be left NA. The a_ij should have the z value for the

Hi, I'm getting horrible performance on my samba server, and I am unsure of the cause after reading, benchmarking, and tuning. My server is a K6-500 with 43MB of RAM, standard x86 hardware. The OS is Slackware 10.0 w/ 2.6.7 kernel I've had similar problems with the 2.4.26 kernel. I use samba version 3.0.5. I've listed my partitions below, as well as the drive models. I have a

Hi, I am trying to find m breakpoints of a linear regression model. I used the segmented package. It works fine for small number of predicators and breakpoints.(3 r.v. 3 points). However, my model has 14 variables it even would not work even for just one breakpoints!. The error message is always estimated breakpoints are out of range. Since my problem is time related problem. So I

Dear list, How is the tolerance for a model parameter in an lm() call extracted? I did not see a solution in the documentation for lm(), or predict(), nor in the archives using 'tolerance' as the search string. I also checked into the nlme package, though nothing popped out at me. Sincerely, KeithC.

I have two Internet connections which connected to different ISP. one is for normal usage , 2nd one is for backup fault tolerance how do I implement fault tolerence multiple internet connections in shorewall ?

Hi people, Now I am using the version of gluster 3.6.2 and I want configure the system for fault tolerance. The point is that I want have two server in replication mode and if one server down the client do not note the fault. How I need import the system in the client for this purpose.

Hello, I have been using the step() function for stepwise regression and was wondering if there was a way to specify a tolerance level either using step() or another stepwise function. So far I have only found an option to specify tolerance in lm.fit() but I am not an experienced R user and am not quite sure if this command can be implemented using a stepwise function. I have tried simply

Hello, We are trying to use R to simulate a model based on parameters 'a' and 'b'. This involves the following integration: model<-function(s,x,a,b)(exp(-s*x*10^-5.5)*(s^(a-1)*(1-s)^(b-1))) g<- function(x,a,b){ out<-c() for (i in 1:length(x)){ out[i]<-1- (integrate(model,0,1,x[i],a,b)$value / beta(a,b)) } out } x<-

Hi people... I want know if Source Codes Virtulization Solution from Red Hat has be release? Thanks -- Gilberto Nunes

dear all i have a web server on centos 4.6. i have configured one more back up Webserver with the same configuration as the same on the primary web server Now how to configure this servers for fault tolerance. that is. if one server gets down the other should automatically become up. Please any one help me out how to configure the above. i am new to Linux ... Regards, Gopinath M Signal

Hi all, When I ran the experiments to compare an application''s execution time in both a domU (named cctest1) and a native Linux machine (named ccn10), I noticed the application executes faster in domU. The host of the domU (named ccn9) and ccn10 are two nodes of a cluster and they have same hardware configurations. domU (cctest1) is created by exporting loopback files from dom0 on
