The use of F for False and T for True
Sampling with and without replacement I seem unable to use "replace = F" when I want to sample without replacement. I would think that it comes down to "F is not a legitimate abbreviation for FALSE." except that Dalgaard (p. 118) uses F for FALSE and it works "pairwise.t.test(folate, ventilation, pool.sd = F)" I am having trouble when I try to sample a vector

Subscript in axis label
Dear R help list members, I am experiencing difficulty in trying to generate a subscript '2' in an axis label. Although I can get the '2' into a subscript using expression(), R then forces me to leave at least one space between the '2' and the following character. My label is supposed to read 'N2O concentration (ppm)', and the space between the '2' and

Misuse of $<matn expressions>$ in Rd files
'Writing R Extensions' tells you that $ needs to be escaped in Rd files outside \code and similar. So I was surprised to find that ca 80 CRAN packages have constructions like (from ISwR) \item{\code{folate}}{ a numeric vector, folate concentration ($\mu$g/l). } This does not render sensibly in non-latex conversions, and it is what we have \eqn{} for. That $ needs to be

Headless Linux system for Asterisk
Because of space limitations and because of the location of the punch-down blocks, my * server is located on the shelf in a coat closet. Sadly, there is not enough space (or ventilation) for the monitor and keyboard. This will all change when we move to new quarters, but... Does anyone have experience running Linux/Asterisk without a monitor? What, if any, are the issues? TIA

How big is *your* ego?
http://www.elna-america.com/tech_al_reliability.php Capacitors are one of the components on that motherboard that have a finite life span. Other components are more or less tolerant of these changes over time. Eventually the caps WILL fail...this could be 5 years or 25, but it WILL happen with electrolytics. I have a well maintained, regulated (3 phase power distribution all ups'd

vegan -varpart is bigger than 100% in total?
I am trying to find the percentage of the parameters explaining the bacterial community composition. I have one data matrix with relative abundance of OTUs and one with environmental parameters. I used varpart in vegan package but the values in the venn diagram is bigger than 100% in total.How is it possible? What might be the reason? Thank you library(vegan) gotud <-

Laptop for CentOS-5
I have a defective HP-Compaq nx9420 and so I am looking to replace it. I have pretty much decided to buy no further MicroSoft based products and would very much like to hear recommendations for a suitable notebook host to provide me with Linux based alternative. Given that all the basic functionality required is provided, the main thing that I am looking for is reliability of the host itself. I

[newbie] how to find and combine geographic maps with particular features?
SUMMARY: Specific problem: I'm regridding biomass-burning emissions from a global/unprojected inventory to a regional projection (LCC over North America). I need to have boundaries for Canada, Mexico, and US (including US states), but also Caribbean and Atlantic nations (notably the Bahamas). I would also like to add Canadian provinces and Mexican states. How to put these together? General

.Net Framework Wrapper
I am going to attempt to develop a wrapper for the R.dll library in the .Net framework. I successfully interfaced with some very simple functions from the library, but nothing close to do some data analysis. I dumped all the "publicly" available functions and attributes from the windows dll and found there are 2671 functions and attributes. I created an API document that

Using Wine - Random machine switch-off?
Hi, I'm wondering if anyone else is experiencing this... I'm using an ASUS X59GL using Ubuntu 10.10, 64 bit - 4Gb ram, nvidia Nvidia GeForce 8200M G (256Mb Graphics?) - I'm using the Nvidia drivers too... I can play a game (Star Wars Rebel commando / Tomb Raider Underworld), however, at random times the system crashes - big style, to the point that the entire machine just switches

ATA with pulse dialing support over FXS
Hi. Does anyone know about a simple one-fxs ATA with pulse dialing support that can work with Asterisk? A SIP one would be ok. I've been told that the Digium S101i IAXy does support pulse dialing; although it's a iax2-only ata it could be enough. I need a bunch of them to convert some old fashioned rotary phones into VoIP ones (I'd like to disassemble the ATAs to remove the boards

samba failover plan on unix OS using hardware RAID
Hi all, I've been asked to produce a plan for samba failover for an office with about 30 2000/XP machines and a few unix servers. We currently have a FreeBSD single-harddrive SCSI box providing samba, dhcp and dns services. Reliability and cost are the priorities, in that order, over speed/performance. We just need the reliability - we don't ever ever want to have to switch to a new pdc.

Windows guest eats as many CPU as available
Hello, I run Debian on my Laptop Lenovo X60s (with VT). I've created a Windows-XP as well as a Windows-Vista guest on it. Both, XP as well as Vista, eats as many CPU as available. Therefore the CPU always has high load and will never reduce cpu-frequenz or ventilator. Did this works as designed or should I modify something? Thanks in advance Matthias -- Don't Panic

Anyone know of a pass through ATA
Anyone know of a company that makes a pass through ATA? By pass through I mean have an Ethernet switch built into the ATA, like most desktop phones have. All of the dual ethernet ATA's I have seen have WAN/LAN ports, not two LAN ports. I fooled around with DMZ etc...but it just doesn't work as well.

Memory problems with CentOS box
Hello all I am running CentOS 5 on a small server and I am having very strange memory malfunctions. The computer runs perfectly with no problems whatsoever. From time to time, after a soft reboot, the computer emmits beeps corresponding to a memory fault. It never reboots again until I find and remove a now defective DIMM. That DIMM can never be used again because it is out of order. This just
