Hi R users, Wonder if somebody could give me help on how to reshape this type of data: ----------------------------------------------------------------------------------------------------------------------- Date:10.09.19 Time:21:39:05 Lat:N62.37.18 Long:E018.07.32 0000-0010 | 28| 28 0010-0020| 302| 302 0020-0030| 42| 42 0030-0040| 2| 2 0040-0050| 1| 1 0060-0070| 1| 1

I'm booting the default kernel on a dual quad core Xeon machine. I only see four CPUs and I expect to see 8. Do I have to build a custom kernel? Is there a switch or configuration parameter I need to set? Thanks, Jerry -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I am looking for dual or quad fast ethernet NICs that work with CentOS. There is no need for high performance so regular fast/pci is ok. -------------- next part -------------- An HTML attachment was scrubbed...

For a new file server that doesn't really do much other than run samba, is there any advantage to quad core CPUs vs dual core? Say the two options are equivalent in price. Thanks, Mark

Dear R-users, I use R to run spatial stuff and it takes up a lot of ram. Runs can take hours or days. I am thinking of getting a new desktop. Can R take advantage of the dual-core system? I have a dual-core computer at work. But it seems that right now R is using only one processor. The new computers feature quad core with 3GB of RAM. Can R take advantage of the 4 chips? Or am I better off

Hi people, Do you have pointers to web documents that help me make comparisons between buying a server with two quad core 2.33 ghz or buying a 4 dual core 2ghz server? I am trying to answer a question of performance. It is not important the redundancy/failover or the price of the server. Just the performance. obviously all the hardware specs are the same, the question is the CPU. --

Dear all, I am managing a departmental purchase of an Opteron based workstation/server for scientific computing on which we will be running R. The environment will probably be either Unix/Linux or Solaris and the amount of RAM will be 8-16Gb, depending on the number of processors. My main concerns are the following: 1. How much does R benefit from passing from one processor to two/four

hi! anyone please recommend/guide me of purchasing a resonably high performance server system regarding processor(s) & motherboard (+ other compulsary peripherals i.e. VGA, Soundcard).

What have I done wrong? I installed an xp (service pack 2) domU using the virt-install example from the man page, on a zfs volume. I noticed this behavior on build 129, and I replicated the behavior on build 130: root@opensolaris:/tmp# virsh version Compiled against library: libvir 0.7.0 Using library: libvir 0.7.0 Using API: Xen 3.0.1 Running hypervisor: Xen 3.4 root@opensolaris:/tmp#

Hello, I am new to non-linear growth modelling in R and I am trying to reproduce an analysis that was done (successfully) in S-Plus. I have a simple non-linear growth model, with no nesting. I have attempted to simplify the call as much as possible (by creating another grouped object, instead of using subset= and compacting the fixed and random expressions.) This is a what the grouped

Dear all, I would like to conduct a Pearson's correlation using cor.test separately for each individual in my data set. Each individual has nine observations of the measurement variable 'Delta13C'. I can figure our how to do it manually one 'Individual_ID' at a time, but I cannot figure out how to automate the process (a loop I am guessing). In addition, I would like to

Do you have anything detailing what the goal of each phase in Xenrt is? Phases 4 and 5 seem to be pretty much identical. Thanks, Paul Larson _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Dear list, The below dataset and code creates a new dataset with the results from the function cor.test being performed on each individual ('Individual_ID') from my original dataset. How do I convert each variable from the cor.test results to a numeric data type, as it is passed into the new dataframe? For example, 'estimate', 'p.value', and 'conf.int' should be

I have MySQL Cluster set up for OpenSIPS which allows for the best Redundant High-Availability. I was wondering if it's possible for Asterisk to also use multiple database servers for Realtime? Currently with Realtime I am only able to point to a single IP address for a database. If that database server goes down that Asterisk is pointed to then Asterisk won't be able to do anything.

I start my dovecot with the "-c /path/to/custom/config" option so I can run multiple instances. Been trying out 2.0.1 so I can upgrade my boxes cleanly, but I require managesieve. So after installing the latest sources of the Pigeonhole plugin, I'm getting this when trying to start dovecot: # /usr/local/sbin/dovecot -c /usr/local/etc/dovecot/dovecot_custom.conf managesieve(root):

Hi, I was trying to write a RESTful service and was planning on testing via tools such as cURL and the basic http libs. With the InvalidAuthenticityToken piece that is turned by default in Rails 2.0.2, I have to provide the token with each request. This is something of a pain for a programmable client that may not make a GET request before performing other actions, specifically POST, PUT and

Hi all Does Digium make a quad BRI card? I can't see anything of the sort on their page but I thought they might call it something else in the States. Failing that, can anyone recommend a make/model that would handle 4 BRI ports? -- Cheers Wayne

I've installed the rpm's and everything seems to be set up fine. I've been through many documents (even the one on redhat that says i must change localhost to 127.0.0.1 in one of the config files (/etc/xinetd.d/swat). When i direct mozilla to http://localhost:901 I get, "The connection was refused when attempting to contact localhost:901 I think maybe that something is not
