similar to: File checking problem

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

Hi, All. I have a data frame with the part as : ..... 142 2006-02-22 16:28:18 useractivity_act 8 0 143 2006-02-22 16:28:26 4 2 0 144 2006-02-22 16:28:28 3 3 0 145 2006-02-22 16:28:31 4 4 1 146 2006-02-22 16:28:35 3 159 0 147

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. Rep[grep('context_log',log1$Remain[1:length(log1$Date)]),]<-"2" Rep[grep('gs',log1$Remain[1:length(log1$Date)]),]<-"5"

hello list, I'm trying to write a script that will search through a directory of trace logs for an oracle database. From what I understand new files are always being created in the directory and it's not possible to know the exact names of the files before they are created. The purpose of this is to create service checks in nagios. Because you don't know the names of the files ahead

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 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, 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

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, 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

Posted this to xen-users back in Oct (http://www.gossamer-threads.com/lists/xen/users/186768), but just confirmed that I''m still seeing this behavior on 4.1. Polling the UCE-SNMP-MIB::ssCpuRawIdle counter results in a total that''s double the actual number of cpu''s on the system, so for example: nms ~ # snmpwalk -v 2c -c ''XXX'' xen1

Has anyone noticed a delay in sending DTMF to zaptel devices? I have a T100P connecting to an NACT telecom switch. All calls are sent just fine, but there are 4 seconds of delay between when the channel goes off-hook & the digits are collected by the NACT switch. I also have some cisco 5300 boxes connected, but there is no delay. Any ideas? -g

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,Barry. Thanks a lot for your details reply. I have already rewritten the programs. Now it totally works. Your comment: " Note the use of comments and breaking the code up into small independent, testable functions" is really Valuable! Thanks again. Hi,David, You are right, My previous code was really horrible. Its not good to make multiple codes at the same time, sometime I feel

I'm on freeBSD 7.0, wine 0.9.53. When I run Orcad, it can load projects, but schematics never open (unlike other users' experiences in the apps db from Orcad v9.0). You open schematics by expanding them in the 'project' treeview window, and under wine, the little "+" box next to the treeview just dissapears when you click on it instead of expanding.

Hi, everyone This proposal covers the OpenProjects idea 'Port the Bigloo Scheme compiler, from Manuel Serrano at INRIA Sophia-Antipolis, to output LLVM bytecode.' There is not a popular functional language frontend yet on LLVM. To my knowledge, this is mostly because LLVM is lack of runtime support for the functional language needs, and C foreign function interface calls are relatively

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
