similar to: error with surf.ls in spatial

Hi there, I use the surf.gls() function to fit a variable measured over a surface. When I plot the predicted surface, there are local minima/maxima in almost every coordinate where data were measured, which seems aberrant. For instance: ?? x <- c(343,293,343,243,293,343,443,543,593,243,293,343,393,443,493,543,593,143,193,243,293,343,393,443,

Hello, I am searching for an internet usb surf-stick (umts) that works under CentOS. Is anyone using such a stick and if so, which chip has this usb-stick? Would a Huawei E160E chip work under CentOS? Or maybe under CentOS with the 2.6.35 kernel from elrepo? Thank you very much! regards Olaf

In an experimental setup we obtain z-data samples at equidistant grid points. The surf.gls (Kriging) algorithm produces an error under this circumstance when performing the Choleski decomposition. A workaround is to dither the grid coordinates using (x <- rnorm(length(x)) ; y<- rnowm(length(y))). Question: Is this an expected behaviour of the surf.gls function ? Regards, Berthold

Although the 'spatial' documentation doesn't mention that extractAIC works, it does seem to give an output. I may have misunderstood, but shouldn't the following give at least the same d.f.? > library(spatial) > data(topo, package="MASS") > extractAIC(surf.ls(2, topo)) [1] 46.0000 437.5059 > extractAIC(lm(z ~ x+I(x^2)+y+I(y^2)+x:y, topo)) [1]

I just installed CentOS 4.2 on a system that was running RedHat 9. Now the browser (Mozilla Firefox) can't connect to web sites via their name (www.google.com <http://www.google.com/> ). It can however connect if the IP address is used (66.102.7.147). Also the 'dig' command times out with either the name or the IP address. Has anyone else seen this? Any pointers would be

Hello, I am looking into description of surf.ls(spatial) and see under value $beta - the coefficients. When I use polynomial of degree 2 to fit surface I expect to get 4 coefficients: z = a_1 x^2 + a_2 xy + a_3 y^2 + a_4 What do beta really stand for and why do I get $beta vector of length 6? Thakns, Mark

I have a general question about using thin plate splines in the surf and ordisurf routines. My rudimentary knowledge of a gam is that with each predictive variable there is a different smooth for each one and then they are added together with no real interaction term (because they don't handle this well?). Now, If I have two variables that have a high D^2 score and a low GCV score (I am

My production server is using mongrel_rails on Ubuntu linux. With Firefox I can reach my production server with the URL: www.mydomain.com:3000/ but I can''t reach my production server with the URL www.mydomain.com/ Is there a way to configure mongrel so that I can reach my production server with the URL www.mydomain.com? -- Posted via http://www.ruby-forum.com/.

Ah, no, you misunderstand. Asterisk wouldn't care one little bit what is on the page - Chromevox would do all that. A screenreader usually tabs or arrows their way about, selecting headings to read content. Thus, Asterisk ONLY needs to be able to hear content FROM the browser and pipe it to the channel, and pass keypresses back TO the browser. The human is the parser, if that makes sense?

Has anyone attempted making the web phone accessible? I can only find one company which operated between 1996 and 2000. I was thinking, install Chrome with Chromevox, headless, on a server, and use something like an AGI to send basic keyboard commands to navigate a page, as a screenreader user would, and pipe the audio back to a channel, to be streamed by Asterisk. (Bear with me here - it's

Dear list: I have a problem I cannot handle yet, and need to solve it as soon as possible. Would be very greatful with anybody who can help me. I have a 512/512 link to internet, that I want to share between several computers. I have eth0, with a public IP address, conected to Internet, and also, eth1, with a private IP address, for network with the surfing computers. I have a main class with
