Dear R-users, I am looking for an elegant way to change some levels of a factor column in data frame according to a condition. Lets look at the following data frame: > data.frame(crit1=gl(2,5), crit2=factor(letters[1:10]), x=rnorm(10)) crit1 crit2 x 1 1 a -1.06957692 2 1 b 0.24368402 3 1 c -0.24958322 4 1 d -1.37577955 5 1 e

Dear R experts, I have a problem with a function I wrote. The fuction looks like this: series<-function(x,s){ foo<-list(); ind3<-integer(); for (j in diff){ for (i in 1:(n-12)){ if (!(x[i,j]==0)&!(x[i+1,j]==0)&!(x[i+2,j]==0)&!(x[i+3,j]==0)&!(x[i+4,j]==0)&!(x[i+5,j]==0)&!(x[i+6,j]==0)

We had a situation over the weekend with our production database that we can't figure out, hoping someone can shed some light.

We shut down the database for san

I am trying to override variables in a class that is defined in the default node profile. I want parent class to be included in every single node, but override its variables in others. I have tried it several different ways now, and every single time the variables either become unset (undefined) or are set to the value of the first if statement. Here is my current iteration of failure.

samba-3.0.10-1.4E on RHEL4-AS. I've got a test domain setup and working just fine. Windows XP clients are authenticating just fine. The only problem I have so far is my domain browser list is not correct. I can see everything in my subnet fine, but can't see anything outside my subnet. This is different than my NT4 domain, who's browse list shows me every domain within the larger

Dear all, I am a newcomer to R programming, I met the problem: I have a lot of .txt files in my directory. Firstly, I check whether the file satisfies the conditions: 1.empty 2.the "Rep" column of the file has no "useractivity_idle" or "useractivity_act" 3.even The "rep" has both of them, numbers of "useractivity_idle"==numbers of

Dear All, I have many files in my directory. I want to transfer each data into one which is readable. They have so many possibilities, i have collected(manually and visually) all possibilities and represent them as different numbers.

Hello, I have being trying to estimate the parameters of the?generalized?exponential distribution. The random number generation for the GE distribution is?x<-(-log(1-U^(1/p1))/b), where U stands for uniform dist. The data i have generated to estimate the parameters is right censored and the code is given below; The problem is that, the newton-Raphson approach isnt working and i do not know what

Hello, When i run the code below from Weibull distribution with 30% censoring by using optim i get an error form R, which states that Error in optim(start, fn = z, data = q, hessian = T) :? ? objective function in optim evaluates to length 25 not 1 can somebody?help me remove this error. Is my censoring approach correct. n=25;rr=1000 p=1.5;b=1.2 for (i in 1:rr){ q<-c(t,cen)

Hello, I want to estimate the exponential parameter by using?optim?with the following input, where t contains 40% of the data and q contains 60% of the data within an interval. In implementing the code command for optim i want it to contain both the t and q data so i can obtain the correct estimate. Is there any suggestion as to how this can be done. I have tried h<-c(t,q) but it is not working

Hi, R-users, I have a problem: Because there are few files which can't be readed into R completely, so on the following subsequence programme, I use write.table, which creates the "NA" files for those incomplete files autimatically. I don't want those NA files. My programes formats looks like: name_c<-Sys.glob("C:/Documents and Settings/lma/My

Dear All, Can you help me, with the code below how do I obtain the fisher information from it. Is my q<-replicate(1000,x) the right way to do simulation. thank you. x<-rweibull(100,0.8,1.5) q<-replicate(1000,x) z<-function(p){ beta<-p[1] eta<-p[2] log1<-(n*log(beta)-n*beta*log(eta)+(beta-1)*sum(log(x))-sum((x/eta)^beta)) return(-log1) } zz<-optim(c(0.5,0.5),z) zz Chris

Hi all, I was hoping to get some advice about a problem that I realize will be difficult to reproduce for some people. I'm running R 1.7.1 on an openMosix (Linux) cluster and have been experiencing some odd slow-downs. If anyone has experience with such a setup (or a similar one) I'd appreciate any help. Here's a simplified version of the problem. I'm trying to run the

Hi, Wine documentation says that it can be installed anywhere, locate its libraries and just run. This is certainly true for self-compiled sources which could e.g. be run from their compiled location. I wonder if this is also possible with pre-built Debian/Ubuntu binary packages. Normally, Debian installs exactly one version of a package in /usr/. Is there some possibility to use multiple

Hi Everyone, In order to make life easier and to do debugging easier I want to observe "sip set debug originator" and "sip set debug terminator" on two different putty screens. Trick is that originator calls the terminator. I can of course put two separate calls and get sip debugs at different times but that's not what I want to do. I want both to spit out on my two
