-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I installed centos4 on a raid system with 7 400GB Hitachi SATA disks in RAID 5 on the 3Ware card. I set up a 2.2TB EXT3 Partition /opt. After the install I rebooted and the system went straight into maintenance mode....! The system reported a problem with /opt, but I was able to mount it manually and init 4 with no problems. However a reboot dropped

Hi, I'm in the process of trying mdadm for the first time I've been trying stuff out of tutorials, etc. At this point I know how to create stripes, and mirrors. My stripe is automatically restarting on reboot, but the degraded mirror isn't. -- Drew Einhorn -------------- next part -------------- An HTML attachment was scrubbed... URL:

I'd vote for it to stay. It could of course suprise someone who'd expect c(list(a=1), b=2, use.names = FALSE) to generate list(a=1, b=2, use.names=FALSE). On the upside, is the performance gain from using use.names=FALSE. Below benchmarks show that the combining of the names attributes themselves takes ~20-25 times longer than the combining of the integers themselves. Also, at no

>From comments in http://stackoverflow.com/questions/24815572/why-does-function-c-accept-an-undocumented-argument/24815653 : The code of c() and unlist() was formerly shared but has been (long time passing) separated. From July 30, 1998, is where do_c got split into do_c and do_unlist. With the implementation of 'c.Date' in R devel r71350, an argument named 'use.names' is

Hello, I have a basic question. Sorry if it is so evident.... I have the following data file : http://ekumen.homelinux.net/mydata.txt I need to model Y~X-1 (simple linear regression through the origin) with these data : load(file="mydata.txt") X=k[,1] Y=k[,2] aa=lm(Y~X-1) dev.new() plot(X,Y,log="xy") abline(aa,untf=T) abline(b=0.0235, a=0,col="red",untf=T)

Dear R-users, I'm studing a DB, structured like this (just a little part of my dataset): _____________________________________________________________________________________________________________ Site Latitude Longitude Year Tot-Prod Total_Density dmp Dendoudi-1 15.441964 -13.540179 2005 3271.16 1007 16993.25 Dendoudi-2 15.397321 -13.611607

Hi R user I need to read in some values from a computer program output. I can't change the output format because the developer of the program doesn't allow to change the format of output. There are two formats. First one looks like this if I have 10 variables, ------------------------------------------------------------------------------------------------------ [ 1]

Dear R users, I am not good in R-language programming. So, i need your help. I want to convert my lower-triangle value of symmetry matrix into a vector with their row and column name. I found a function called "sm2vec" in "corpcor" package but it give only a vector of values but not row and column names. But i also want ROW and COLUMN name together with their corresponding

Hello, I hesitate to call this a bug, because I could have forgotten something important, but the MarkowitzPortfolio example in fPortfolio does not work for me. Here's my code: > library(fPortfolio) > >xmpPortfolio("\nStart: Load monthly data set of returns > ") > data(berndtInvest) > # Exclude Date, Market and Interest Rate columns from data

Dear R-Helpers, I've looked high and low for a function that provides frequencies, proportions and cumulative proportions side-by-side. Below is the table I need. Is there a function that already does it?

Sadly you failed to set your email program to send plain text and the data is corrupted at my end. I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis. I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need

OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here. My question is related to systemfit; I don't know how to get the result for the entire panel. #Reproducible script Empdata<- read.csv("/Users/ngwinuiazenui/Documents/UPLOADemp.csv") View(Empdata) install.packages("systemfit")

  Dear R helpers   Suppose I have two sets of ranges (interest rates) as   Range 1 : (7 – 7.50, 7.50 – 8.50, 8.50 – 10.00) with respective probabilities 0.42, 0.22 and 0.36.     Range II : (11-12, 12-14, 14-21) with respective probabilities 0.14, 0.56 and 0.30 respectively.     My problem is to form the combinations of these ranges in a decreasing order of joint probabilities. It is assumed that

Hello, I have a multi-year dataset (see below) with date, a data value and a flag for the data value. I want to find the monthly median for each month in this dataset and then plot it. If anyone has suggestions they would be greatly apperciated. It should be noted that there are some dates with no values and they should be removed. Thanks Emily > print ( str(data$flow$daily) )

Hello. A couple of years ago I installed two file-servers using kickstart.
