Re: [R] Value-at-Risk Portfolio(both equity and option)
One thing that comes to mind immediately is the 'blotter' package which I believe is designed to handle and track multiple instruments. A sloppy temporary solution I guess would be to do some type of lookup or a flag that denotes which instrument is an option and apply the VaR methodology appropriately. I am not in front of my desktop for now, else I would dig around the blotter code to evaluate a proposal to handle the scenario you mention. Perhaps some people who have done more work with these types of issues can shed more light on this. Hth -c On 3/31/10, zhang yn19...@msn.com wrote: Thank you very much. It is very helpful.

Re: [R] cluster-lite
perhaps a long shot but maybe the package 'nws' could handle some of it. I've recently begun looking into something similar lately as well. -c ivo welch wrote: I am about to write a cluster-lite R solution for myself. I wanted to know whether it already exists. If not, I will probably write up how I do this, and I will make the code available. Background: we have various linux and OSX systems, which are networked, but not set up as a cluster. I have no one here to set up a cluster, so I need a hack that facilitates parallel programming on standard networked machines. I have accounts on all the machines, ssh access (of course password-less), and networked file directory access. what I am ultimately trying to accomplish is built around a simple function, that my master program would invoke: master.R: multisystem( c(R slv.R 1 20 file1.out, R slv.R 21 40 file2.out, ssh anotherhost R slv.R 41 80 file3.out), announce=300) multisystem() should submit all jobs simultaneously and continue only after all are completed. it should also tell me every 300 seconds what jobs it is still waiting for, and which have completed. with basically no logic in the cluster, my master and slv programs have to make up for it. master.R must have the smarts to know where it can spawn jobs and how big each job should be. slv.R must have the smarts to place its outputs into the marked files on the networked file directory. master.R needs the smarts to combine the outputs of all jobs, and to resubmit jobs that did not complete successfully. again, the main reason for doing all of this is to avoid setting up a cluster across OSX and linux system, and still to make parallel processing across linux/osx as easy as possible. I don't think it gets much simpler than this. now, I know how to write the multisystem() in perl, but not in R. so, if I roll it myself, I will probably rely on a mixed R/perl system here. This is not desirable, but it is the only way I know how to do this. if something like multisystem() already exists in R native, please let me know and save me from reinventing the wheel. if it does not, some perl/R combo for this soon will. regards, /iaw __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

In addition: Warning messages:
1: In structure(.Internal(as.POSIXct(x, tz)), class = c(POSIXt,
POSIXct), :
unknown timezone 'merica/New_York'
Strange thing: I set up the same thing with R2.9.0 (and as expected, I got
warnings when loading libraries that were built on 2.9.1, but that's ok) --
everything above works with 2.9.0 fine and dandy.
I am wondering how could the TZ, which is America/New_York become a
malformed character ('A'). It seems to be either a RODBC issue or something
more sinister under the hood with retrieving the TZ environment variable?
Note, this all works in 2.9.1 if the TZ variable is set to GMT. I can live
with that for the time being as a workaround. To further aid in debugging,
I've attached my sessionInfo output:

Any help would be much appreciated.

Re: [R] Standalone program from R script
You could perhaps try Rserve (I'm not sure of your level of familiarity with Java, and the full functionality required of your application) or . From Gabor's link: Take a look at Rwui: http://rwui.cryst.bbk.ac.uk/ Or, my roundabout way of solving problems like this suits you: Basically if all you need to do is have coordinates sent to this R app/formula/script and then output spit out via either an image or textual format, that should be pretty easy to do with Rserve and a few hours with Java and an applet. Have the applet accept inputs (coordinates?) and then send them to Rserve. Once Rserve/R is done, pickup the image or text generated and have it display in the applet. HTH, cj -- Cedrick W.

The program takes the co-ordinates through mouse-click at any point of the co-ordinate plane and then does the necessary computations. But the guys for whom I wrote the program , are now demanding a standalone program, ie they don't want their users to install R first to use this facility. So is there any way, without switching over to any other language, to change a R-script to a standalone program , it 'll be great even if a web-application is possible, I mean, the client will send the co-ordinates, R 'll be installed at server side and after the computation the results will be sent back to the client. So please tell me, if anyone of this two(standalone desktop program or web application) is possible.
