Hello, I'd like to use package 'doSMP'. But I can only found source codes in the CRAN. I tried to build source code using 'r CMD build doSMP' in the source directory, the following error is shown: ERROR: dependencies 'foreach', 'iterators', 'revoIPC' are not available for pack age 'doSMP' So, i tried to install dependency packages. But I

Hi list, I was testing out the "doSMP" package from REvolutionR in my regular R2.11.0 installation and I got the following error message.? Well, one obvious thing is that R2.11.0 was built using "i386-pc-mingw32" which is different from what revoIPC used.? I could just use REvolutionR, but all my R peripherals were set up to work with the regular R2.11.0.? So, I really want

Hello dear list, I just noticed that: Package ‘doSMP’ was removed from the CRAN repository. http://cran.r-project.org/web/packages/doSMP/index.html Does any one know the reason for this? Is this a technical or a legal (e.g: license) issue? Thanks, Tal ----------------Contact Details:------------------------------------------------------- Contact me: Tal.Galili@gmail.com | 972-52-7275845

Some might have noticed that REvolution Computing released the doSMP package to the general public about a month and a half ago, which allows multiple cores to be accessed for parallel computation in R. Some of our physical habitat calculations were taking an extraordinary amount of time to complete and required over-weekend runs, which prompted our interest in this package. What follows

Dear all, I am looking at the R-help entry below: http://finzi.psych.upenn.edu/R/Rhelp02/archive/26640.html I have a more complicatedt problem. I have a zoo time series frame with 100+ sequences. I want to cycle through them back and forth and compare them to the 1st column at any time. I need also a button to click when I need the viewed-selected sequence (that is being compared to the

Hello, I have a zoo time series read from an excel file which has some dates the same, such as the following example: 02/10/1995 4925.5 30/10/1995 4915.9 23/01/1996 4963.5 23/01/1996 5009.2 04/03/1996 5031.9 # here 04/03/1996 5006.5 # here 03/04/1996 5069.2 03/05/1996 5103.7 31/05/1996 5107.1 01/07/1996 5153.1 02/08/1996 5151.7 Is there a

Hi, I have two zoo objects (time series of same frequency) say A and B. I need to exchange A's dates for B's. Is there and easy way? I managed to do it by converting A to a vector and pasting it on a zoo vector (all ones) with B's dates but I wonder if there is an easier way by some "zoo" command I have overlooked... Thanks in advance, Costas

Hello again, I merge different zoo time series with prices at different dates. This returns a multivariate zoo object with NA's at various points i.e., 2010-02-28 NA NA NA NA 850.2 2444.4 NA NA NA NA NA NA NA 2010-03-01 61.1 55.3 61.5 81.24 NA NA 1712.2 3.3 11139.3 163.7 2242.4 9015.6 109.791 2010-03-31

Hi, I would like to get suggestion about parallel computing package on a multicore windows workstation. I tried doSMP, but it crashes R a lot. I am wondering if "snow" and "snowfall" can be used on a single workstation (i,e, not cluster). At suggestion would be appreciated, Best, Richard [[alternative HTML version deleted]]

My parallel code is running slower than my non-parallel code! Can someone pls advise what am I doing wrong here? t and tTA are simple matrices of equal dimensions. #NON PARALLEL CODE nCols=ncol(t) nRows=nrow(t) tTA = matrix(nrow=nRows,ncol=nCols) require(TTR) system.time( for (i in 1:nCols) { x = t[,i] xROC = ROC(x) tTA[,i]=xROC } ) user system elapsed 123.24 0.07 123.47 #

Hi all, I would like to parallelize some R code and would like to use the 'foreach' package with a foreach loop. However, whenever I call a function from an enabled package outside of MASS, I get an error message that a number of the functions aren't recognized (even though the functions should be defined). For example: library(foreach) library(doSMP) library(survival) # Create the

Dear R-List member, I have a problem when I'm trying to save two arrays from a foreach-loop. I'm also not sure whether this is possible or just my inexperience. However, this works perferctly fine with a for-loop. Here is an example code - any help is much appreciated!!: ############ n.vpn = 2 n.run= 3 # create to empty matrices sme = matrix(NA,4,n.vpn) test = matrix(NA,4,n.vpn) #

Hi all, I have setup dovecot 1.1.4 and sendmail 8.14.3 with dovecot LDA on linux (RHEL5 on x86_64). I have deliberately set a very low quota (4MB) on a test account, while the actual disk usage is 5MB at the moment, in order to test overquota behaviour.. When I send an email to this account, sendmail accepts the email and tries to deliver it. Deliver fails to save in INBOX and returns an

Hello, this subject came up yesterday in ##xen@freenode.net In an Ubuntu 10.10 (maverick) domU, using /dev/xvda in ------------- mavU.cfg --------- disk = [ "phy:/dev/VG/mavU,xvda,w" ] # ------ snip cfg ------ leads to `rootfs not found` errors and the domU will not finish booting.
