R: Help; error in optim
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)

Optim Problem
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

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

About warnings for non-matched items
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.

R-help: Censoring data (actually an optim issue
Your function is giving NaN's during the optimization.
The R-forge version of optimx() has functionality specifically intended to deal with this.
NOTE: the CRAN version does not, and the R-forge version still has some glitches!
However, I easily ran the code you supplied by changing optim to optimx in the penultimate
line. Here's the final output.

find errors in a directory of files
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

Problem with Newton_Raphson
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

matrix with Loop
Hello!
I got something to ask..whether you can help me with the R program...i got this for example 5x4 matrix..and i want to find:
?i) mean for each row of the matrix
ii) median for each column of the matrix
and i need to do this using a loop function...below is my program..u try to check it for me as the output that i got is not what i desired...thanks..

Please Help me!
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:

using several wine versions from .deb packages?
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

Orcad 7.2 (old) loads, but treeviews won't expand
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.

[GSoC'16] Add a Scheme Frontend for LLVM
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

Using log() on an openMosix cluster
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.

File checking problem
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
