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,] 

Hi everybody. I want to identify duplicate numbers and to increase a value of 0.01 for each time that it is duplicated. Example: x=c(1,2,3,5,6,2,8,9,2,2) I want to do this: 1 2 + 0.01 3 5 6 2 + 0.02 8 9 2 + 0.03 2 + 0.04 I am trying to get something like this: 1 2.01 3 5 6 2.02 8 9 2.03 2.04 Actually I just know the way to identify the duplicated numbers rbind(x, duplicated(x) |

I am having difficulty understanding how I would constrain a data set by filtering out 'records' based on certain criteria. Using SQL I could query using 'select * from my.data where LithClass in ('sand', 'clay')' or some such. Using subset, there seem to be ghosts left behind (that is, all of the LithClass *.Labels* remain after subset) > dput(tcc)

Hi, I'm trying to create an dynamic dns system by using the nsupdate (or Net::DNS) trough a non-passphrase protected ssh session. I've keygen'ed an extra key, with no passphrase and using it, i execute a litte script on the server, which updates te DNS records. (something like this: ssh pickup /usr/local/bin/updatedns 10.1.2.3) This al works fine and dandy. I would like to protect

Hello, I was unable to find clues to my problem in ?optim. Using the data and code below, I get an error ("system is exactly singular") when a particular line of code is left in, but have found that 'optim' works when I comment it out. The line of code in question is after the closeAllConnections() line of code and contains a call to "na.approx" from the zoo package.

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 all! We use pxelinux for booting a diskless Linux from whitch we install all our systems. But we discovered some Problems: - With v1.75 the Kernel is fetched from the TFTP-Server with no problem, but it gets not started on Broadcom NetXtreme with newer PXE-Bioses - With v2.04, pxelinux even seems not to be able to fetch the kernel from the TFTP-Server. This affects also Intel's

Duncan, Below are the tabulated compile times and executable sizes.

Current dragonegg svn has all of the -fplugin-arg-dragonegg-enable-gcc-optzns bugs for usage with -ffast-math -O3 addressed except for those related to PR2314. Using the -fno-tree-vectorize option, we can evaluate the current state of -fplugin-arg-dragonegg-enable-gcc-optzns with the Polyhedron 2005 benchmarks compared to stock dragonegg and stock gcc 4.5.4. The runtime benchmarks below show that

Hi, I've got pxelinux 2.00 working to boot rh 7.3, 8.0, and phoebe-beta pxe install images but I've recently tried to load the rh 9 pxe install images and I get this.. 4000 AX:0208 BX:0200 CX:0002 DX:0000. Any thoughts? Thanks aaron

Duncan, Here are the complete benchmarks rerun against gcc 4.5.4 built with... Using built-in specs.

It seems that 2.03-pre1 resolves PXELINUX problem on a reasonable number of hosts. Perhaps somewhat importantly this seems to include the RBFG PXE boot floppy, which did not work with 2.02. This was somewhat of a surprise, since it didn't exhibit the failure mode that I would have thought would have been the trigger of the bug. Instead, it was one of those stacks that would transmit packets

Dear sir/madam, I encountered some problems when running R on my computer. To be honest, I am only a beginner of computer programming and I have no idea how to deal with it. I have tried to change the font in "system preference" but it did not work. Can you tell me how to get it right? The system of my computer is Mac OS snow leopard The warnings are like these: During startup -

Hi, I just tried to boot my token ring devices with 2.05 - to no avail, it hangs after loading the kernel. I then tried older versions, and found 2.03 booting like a charm, and every 2.04-pre including 2.04 hanging. Here's the config of the devices: - Networkstation 2800 with IBM PCI Token Ring card 2 - IBM Thinkpad T21 with IBM PCI Token Ring card 2 Maybe this has to do with the changes

Hi Jack, thanks for these numbers. Can you also please measure compile times? I'm thinking of enabling gcc optimizations by default, but I don't want to increase compile times, which means choosing a value for the -fplugin-arg-dragonegg-llvm-ir-optimize option that is low enough to get good compile times, yet high enough to get fast code. It would be great if you could play around with

I have a problem with R. I try to compute the confidence interval for my df. When I want to create the plot I have this problem: Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ. I try this code: library(dplR) df.rwi <- detrend(rwl = df, method = "Spline",nyrs=NULL) write.table(df.rwi,file="rwi.txt",quote=FALSE,row.names=TRUE)

Oftentimes I want to make outputs to be displayed on the R console. However, after I execute a program with a sink command in it the R console becomes unresponsive. Meaning that the following occurs in R console: > source("Program_containing_sink.R") > a<-1 > a > >sink() >a > R help says that sink() will bring output back to the console but i's not

Hi, as I just discovered, in recent versions of rsync the "--delete" option seems to not work in certain cases. I couldn't come up with a simple scenario to reproduce the problem, so I'll have to tell the whole story: I use rsync to regularly backup a system onto other disks. The filesystems I want to save are mounted on "/", "/usr/ and "/data", the
