I am using stepAIC for stepwise regression modeling. Is there a way to change the entry and exit alpha levels for the stepwise regression using stepAIC ? Many thanks, Berthold Berthold Stegemann Bakken Research Center Maastricht The Netherlands [[alternative HTML version deleted]]

Hello, I am using the maps library for plotting maps. To build new geograhical sets such as Europe I use europe = c('Germany','Netherlands',...) Is there a list of county codes used by the map function. Thanks, Berthold -- Berthold Stegemann Brunssumstrasse 21a 52074 Aachen Germany Tel: +49 241 401 8909 Mobile: +31 6 2041 4824

After reading a data.frame using, such as a <- read.spss("data.sav") I want to give the column index 'i', or a[i] to a function, which after some calculation, should print out the results to the standard output. I am struggling how to access the data itself, as e.g. sum(a[i]) does not work in this context. In addition I need to know the name of the variable within the

Hi, is there a possibility using the step() function together with a glm() model, to force keeping some of the covariates in the model ?? and not having them dropped ??

Hello! I like to PXE boot the 'Dell 32 Bit Diagnostics' tool. I can create a harddisk image with the linux download package. The README of the Package gives an example how to create an memdisk entry for the pxelinux menu system: <quote> Create a Bootable HDD Image File Use of the resulting image to perform a Preboot Execution Environment (PXE) boot into the diagnostics

Hi, We want to restrict acces to the shares on our samba server using "hosts allow". Can I get this to work with clients who have dynamic IP addresses and don't have revers DNS lookup ?

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

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]

Hello R users, Can someone point me to a solution to the problem below? The surf.ls() call works fine in other contexts, e.g. the example in help(surf.ls). I'm using R 1.3.1, and get the same error regardless of the platform (debian Linux, MS Windows 98).

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?
