    Dear all,
     I need to install an R package entitled "Multicore" in my PC. but I encountered an error message.
     Would you please help me to solve the problem.
     
     the error is as follows:
     When I try to install from zipped file.
    > utils:::menuInstallLocal()
    Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
     cannot open the connection
    In addition: Warning messages:
    1: In unzip(zipname, exdir = dest) : error 1 in extracting from zip file
    2: In read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
    cannot open compressed file 'multicore_0.1-8.tar.gz/DESCRIPTION', probable reason 'No such file or directory'

    Also I didn't find it in any CRAN mirror when I try to install it online.

    My system information is :

    Intel (R) Core (TM) i7-3520m CPU @ 2.9 GHz 2.89 GHz
    Installed memory (RAM)= 3.96
    System type: 64-bit operating System  x64-based processor

    Try the "parallel" package instead; according to http://cran.r-project.org/web/views/HighPerformanceComputing.html it was directly supported starting in R 2.14.0 and replaced "multicore" and "snow".

    As for "multicore", ccording to the documentation (see http://cran.r-project.org/web/packages/multicore/index.html), a POSIX-compliant OS is required (essentially anything but Windows; some Windows variants are supported experimentally, your mileage may vary).

    Dear all,
    Thanks all your attention.
    I got the point.

    mclapply that I want to use is now integrated into R's base as of 3.0. Just need to load the package

    "Parallel". So, no need to have multicore package thought it does not designed for windows.

    Cheers,

    Amir

    Multicore is a unix only package. It may work on a linux computer but it won't run on a PC. It is currently only available through the rforge page. Uf you are running linux try:

    install.packages("multicore",,"http://rforge.net/",type="source")
