I'm finding that readLines() and read.fwf() take nearly two hours to work through a 3.5 GB file, even when reading in large (100 MB) chunks. The unix command wc by contrast processes the same file in three minutes. Is there a faster way to read files in R? Thanks!

I have successfully built R version 2.8.0 RC (2008-10-13 r46702) from subversion director on Ubuntu 8.04. I would like to build a version which uses goto BLAS. Thus far, I've downloaded the academic version of goto blas and run the quickbuild command on my system: ./quickbuild.32bit This command is successful creates a file: libgoto_baniasp-r1.26.so I'm a little vague on

I have created a very simple DialogBlocks project that consists of a very simple wxWizard. I have exported the project to XRC and am trying to get XRCise to process it. XRCise produces the message "Cannot create wrapper for subclass of wxWizard". Is this a symptom of the XPath parsing in Ruby 1.8.6 bug? Or am I doing something wrong? My env: ruby 1.8.6 (2007-03-13 patchlevel 0)

Hi R C. The resulting installation is smaller than the image that you download through FTP, etc. When I first installed this OS during version 5, I was amazed that the installation took a mere fraction of the time it took to go through the menu. Heh. Anyway, give it a whirl as it?s quick. I?m assuming you mean a headless installation. Oh and I?m top posting because it?s logical.

A customer is looking to replace or augment their Sun Thumper with a ZFS appliance like 7320. However, the Thumper was used not only as a protocol storage server (home dirs, files, backups over NFS/CIFS/Rsync), but also as a general-purpose server with unpredictably-big-data programs running directly on it (such as corporate databases, Alfresco for intellectual document storage, etc.) in order to

Does R do its own swapping out to disk? I disabled Linux swapping and the system still gets stuck in Purgatory where there's little CPU activity but the disk goes like crazy. That's with R having almost the whole machine to itself and running a memory hungry compute only function. I've seen this behavior with other version numbers but I'm running R 2.0.0 under Fedora Core 3.

Is there a better way to express operations between matrices and column vectors than transposing the matrix twice? This is the kind of thing I'm talking about: m = matrix(1:20, 3, 4) v = colSums(m) t(t(m) / v) ## <-- kinda ugly, ain't it? I thought of converting the column vector to a matrix: m / matrix(v, nrow = nrow(m), ncol = length(v), byrow = TRUE) But that seems even

All, I desperately need a resolution to this issue. I've asked once (about a day or two ago), but I haven't heard anything back. The only reason I press the issue is I may because without a quick resolution, I may be forced to switch over to AD (cry!). I submitted a request via Bugzilla but I saw a slightly similar problem with 3.0.20a that still hasn't been resolved, so I

Hi all, I'm having a really frustrating time with a bunch of BT-101 phones. They've been trouble-free and working very well for the past several months. A couple of days ago, some of the phones (but not all of them, yet) have started acting very strangely. All phones are running firmware 1.0.6.7, and are identically configured (except for the user/authenticate/password things) on both the
