Hi list, I'm building a backup server for 3 hosts (1 workstation, 2 server). I will use bacula to perform backups. The backup is performed on disks (2 x 3TB on mdraid mirror) and for each hosts I've created a logical volume with related size. This 3 hosts have different data size with different disk change rate. Each host must have a limited sized resource and a reserved space. If a

On a support forum, I was told that to turn off my board's blue led run: echo none | sudo tee /sys/class/leds/blue\:heartbeat/trigger Well, this does not survive a system reboot.? So I was told: Add the off bit to ??? /etc/rc.local Add it above "exit 0" So of course, CentOS is past using rc.local and recommends: # It is highly advisable to create own systemd services or udev

Hello! I would like to convert rows of a matrix to a elements of a list. #For example, if I have mat<-matrix(1:100,ncol=5, nrow=20) #I can do: list<-apply(mat,1,list) list #however this is not quite what I want. To get what I want, I have to do: list<-lapply(list,function(x)x[[1]]) list Is there a faster way? Best regards, Ales Ziberna

I am interested in making a random sample from a uniform distribution of points over the surface of the earth, using the WGS84 ellipsoid as a model for the earth. I know how to do this for a sphere, but would like to do better. I can supply random numbers, want latitude longitude pairs out. Can anyone point me at a solution? Thanks very much. -- Russell Senior ``I have nine fingers;

Dear Roger, I am trying to use the write.polylistShape() function of maptools for the first time and realize that it handles list of polygons of class 'polylist'. However, it seems that no as.polylist() function exist in the package. The question behind that is: in your opinion, which would be the best way to convert a list of matrix of polygon nodes coordinates into an object of

Hi R, I am familiar with the basics of R. To learn more I would like how to get data from Yahoo!finance directly into R. So basically I want a data frame or matrix to do some data analysis. How do I do this? Thank you very much.

...to do it is for the receiver to send a success message back to the sender so that it can remove the source file only when it has been successfully sent. One implementation was to use the redo channel for this ack, and that means that the above no-hang patch would need to be implemented first. An untried implementation would be to use the error channel (from the receiver through the generator to the sender) as a way to send the sender a "delete item X" message. An alternate approach that is conceptually simpler is to add a file- removal pass on the sending side at the end of the transf...

...if you loose the running disks (though it is hardly backup in depth), but what happens if you loose the server due to fire, flood, electrical problems, theft or even plain old dropping it? In general you should aim for multiple backup copies; are you willing to bet the company's future on one untried copy? You should ensure that the backup copies are held preferably off site, failing that in a separate building, or else in a secure fireproof strongbox. Start by assuming you come into work one day to find the building burnt out and collapsed. Now work out how to rebuild your system on new k...

Hi all, I have a set of 54 files that I need to convert from ASCII grid format to .shp files to .bnd files for BayesX. I have the following R code to operate on those files: library(maptools) library(Grid2Polygons) library(BayesX) library(BayesXsrc) library(R2BayesX) readfunct <- function(x) { u <- readAsciiGrid(x) } modfilesmore <- paste0("MaxFloodDepth_", 1:54,

Hi, Has anyone on this list had any success with installing and using Open Cobol on RH or CentOS? Any pointers would be very welcome. I have Googled and am working with Vince on the Open Cobol mailing list to try to resolve installation problems. ChrisG

Hi, everybody! i created a imagem by kriging using geoR package. I imported points from GRASS("zn", after converted to geodata "zn_geo"), the border "zn_border" and a raster mask. Then i interpolated the points by kriging and created a raster image. Now, i need export this image back to GRASS to use it in the module r.mapcalc. I can't do it. I tried use

Dear All, I couldn't figure and couldn't google out how to make construct a pair of \Sexpr s or a LaTeX macro that would include 5\cdot 10^{-12} into the LaTeX output istead of 5e-12 . Any ideas? Thank you G?bor

Hello all, I've got a problem with a function in a R package I've developed (MetaLandSim). One of the outputs of my function is the plotting of four images (combining a graph and a map). This plotting is made in a graphical device, with the graph in one side and the map in the other. My function works perfectly fine until it has to plot the map. Then it stops and I get an error.

Dear R users, I would like to reverse the axes on some xy plots (for example to set the origin at the top left rather than the bottom left). I had planned to use something of the following form: plot(y=y<-c(20,4,5,6),x=x<-c(10,20,30,40),ylim=rev(range(y))) ie reversing ylim to reverse the y axis. This works fine however I also want to use the parameter asp=1 to ensure that equal

...he tables in R are not that nice in respect to the formatting. Since the content is the main thing anyhow, that does not matter. In most cases, the tables have to be tweaked as least to some extent. Given my inexperience, it seems that the R2HTML path is so far the most promising (but for me untried so far) One of the nice things about SPSS and Statistica is that it is VERY easy to copy and paste output from the program right into the paper / paper. A commmon trick when using SPSS is to first paste the output into a spreadsheet (e.g. Excel), and from there into the document. In any cas...

Hi, I am trying to set up a C++ library for my R code. I followed the R-extension manual but found out that the example of "X.cpp, X_main.cpp" is somewhat too simple.

Hi, Does anyone know of a method to validate a DateTime field? I''ve looked at the validation docs and the validates_date / validates_time plug-in but I can''t find a method to validate a value in the format of yyyymmddhhmm. It seems like something that should exist already, so I''d just like to check before I attempt my own version... Cheers, Mark

I need some guidance on what is the best way to automate R I am aware of Rterm. First question: Is it true that R is not currently OLE accessible under Windows 2000? Second question: Is there an R command that echoes all R Console results to a run log system file? My first attempt to write a run log file is the example from the R Data Inport/Export documentation. > zz<-
