Dears, anyone has experiences with text mining and R? I'll be very greatfull for tutorial or examples. Thanks -- Daniele Medri - http://www.medri.org

Dear list, I am sorry to bother you with this. I just upgraded yesterday to R 2.0.0 (using apt-get under Debian Sid), and now have problems running e.g., summary(lm(...)) the lm is calculated, but the summary statement gives me the following error: Error in La.chol2inv(x, size) : lapack routines cannot be loaded In addition: Warning message: unable to load shared library

Hi, I'd like to install the optimized libraries on my Thinkpad with an Intel Core Solo chip, which apparently supports the following instruction sets: MMX, SSE, SSE2, SSE3 instruction sets, XD-Bit. In a recent r-help message, the following was said (by Dirk I think): <quote> Yes, on Ubuntu, use 'apt-get install atlas3-base' for basic tuned Atlas, or 'apt-get install

Hi All, I'm still having significantly difficulty getting the quantreg library running in R. I'm running R on MEPIS using the debs created by Dirk Eddelbuettel and placed in apt testing. When I try to install quantreg using the install.packages() function it fails with: /usr/bin/ld: cannot find -lblas-3 Dirk was nice enough to send me a .deb for quantreg which installs without

I have R under Linux Kubuntu Hardy Heron 8.04 LTS.

Hi everyone, I'm trying to use samba in a small video post production house but we are not getting the performance we expected. Our setup: - CenOS 5.6 x86-64 - samba.x86_64 (3.0.33-3.29.el5_6.2 and 3.6.0rc1) - Intel based server (One 4 core Xeon E5620 @ 2.40GHz, 8 GB RAM) - 4 Intel Gigagit ethernet NIC ports with 802.3ad bonding connected to a switch configured tu use 802.3ad - 8 2TB 7.2

Hi all, I am trying to get some decent speed out of a vanilla Debian (Proxmox) box and am running out of ideas. Basically I can exchange data at 110MB/sec (raw, nfs, ftp) but not with Samba shares. I tried almost every samba tuning tip I could find to no avail. The only optimisation left to smb.conf at the moment is debug level = 0. As one can see the robocopy throughput is merely half of what

On RedHat Enterprise Linux 6, the test below fails (this is using the stock GCC 4.4.7) from R-devel r72707. LC_CTYPE is unset when I run it, but LANG=en_US.UTF-8 It also failed "yesterday" where as far as I recall the test code looked a bit different.

DeaRs, I have a doubt about: BIC (Bayesian Information Criterion) SBIC (Schwartz Bayesian Informarion Criterion) SIC (Schwartz Information Criterion) In many references these are know as the same (eg. stepAIC() function) but I just found a SAS8.2 output that show either the BIC and SIC values for a logistic regression.. simillary values but different. 1) question: What are the differences?

??Hi all! We use Samba 3 server for some video stuff (editing, rendering, and so on) -- that's why performance is critical. We've tried a lot smb.conf options, but Samba can't satisfy our requirements. Our server configuration is as following: * Hard drive: RAID5 (8 x Seagate 7200.10), 3ware 9550SX-8LP controller * NICs (trunked): 2 x Broadcom NetXtreme BCM5704 * Processor: Opteron

I looked for evidence that this is supposed to happen, as it was news to me that it did on some versions of R. Possible sources of documentation seem to be R CMD INSTALL --help ?INSTALL R-intro.texi, R-exts.texi, R-admin.texi none of which mention this AFAICS, and all seem to be written assuming an existing library tree. DId you find something to suggest otherwise? Clearly no alpha/beta

Hi, I'm using Ubuntu Hardy i386, and the R 2.7.1 Ubuntu packages from CRAN. The CRAN r-base-dev package depends on refblas3-dev or atlas3-base-dev, but octave3.0-headers depends on libblas-dev. The two blas packages seem to conflict, so r-base-dev and octave3.0-headers can't be installed together. Is this a known issue? Thanks, Gad $ sudo apt-get install octave3.0-headers Reading

Reading a flat text file 138 Mbyte large into R with a combination of scan (to get the header) and read.table. After conversion of text time stamps to POSIXct and conversion of integer codes to factors I convert everything into one data frame and release the old structures containing the data by using rm(). Strangely, the rm() does not appear to reduce the used memory. I checked using

Hi All, I'm trying to install the quantreg library on my MEPIS box (debian-based linux). When I try >install.packages("quantreg") it fails to loads and errors with: /usr/bin/ld: cannot find -lblas-3.

Hi, I've setup a wlan ap using a an alix 2d2 (AMD Geode LX 500 Mhz + AES Offload) and am now trying to encapsulate the wlan traffic into a vpn (tap bridge). Though even when disabling crypto and digest (there is a crypto engine onboard can be setup to handle tinc encryption), the best throughput I get is aroung 2,9 MByte per second (wget+http) (even if the client is run locally).
