Hello All First - a warning. I'm not very R or programming savvy. I am trying to do something without much luck, and have scoured help-pages, but nothing has come up. Here it is: I have a matrix (m) of approx 40,000 rows and 3 columns, filled with numbers. I would like to convert the contents of this matrix into another matrix (m_p), where the numbers of (m) have been coerced into a

Hi, i've been trying to apply the lme apprach to growth curves of children, but lme keeps running for ever and ever as soon as I use a reasonable basis.

Hi! I'm new to the list. I have a problem with mounting my home directory since my PC crashed. I hope that I can get some help on this list as I don't know much of ext3 myself. The mount command for my /home gives me the following output: # mount /dev/sda6 /mnt/tmp/ mount: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or other error In some cases useful info

Hello, I am trying to fit gamma, negative exponential and inverse power functions to a dataset, and then test whether the fit of each curve is good. To do this I have been advised to calculate predicted values for bins of data (I have grouped a continuous range of distances into 1km bins), and then apply a chi-squared test. Example: > data <- data.frame(distance=c(1,2,3,4,5,6,7),

All: I am tasked with creating an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.)

Hi all, I hope someone here can help me with the following problem: we have a router/firewall machine which connects our local network to the internet. As there are also some servers in the local network working as mail- and webservers, we are using DNAT to make this machines reachable from the internet. The firewall-machine is connected to the internet with two connections, one ADSL connection

Hello, my patch separates usage of the callback between the user, combination effects, and the core effects. Consider these use cases. a) user - core effects b) user - combination effects - core effects For a), the existing callbacks can be used by the user For b), the existing callbacks are partly used by the combination effects as a communication channel to the core effects, therefore they

Hi all!

Hello everybody! For my academic project work I intend to use only open-source software. My objective is to carry out classification of satellite digital images using Geostatistics. I found out GRASS is a good software for image processing. Also a good geostatistics software is R. It is also known that R can be used in combination with GRASS. But I am not able to confirm that satellite digital

Hi, using the attached script to implement an incremental rotating backup of my home directory works fine if I run it myself, however if it is run as root the -- link-dest fails and all files are recreated rather than linked to. Can someone explain the problem to me? I'm using rsync version 2.6.5 on Darwin Kernel Version 8.1.0 (OS X Tiger) Thanks, Simon.

Hi, I would like to know if anyone knows how to compute a variance of the non-linear combination of the coefficient estimates. Say, I get a model of y~c+ax+bz (1) where x and z are the independent variables, c is the constant estimate, and a and b are the coefficient estimates. Then, I want to know the variance of b*c/a (2). How am I going to get it? In Stata, I can just use

Looking at the warnings about not running samba 4 (tp3) in a working environment, because of the missing file printing features make me wonder if one could get away with only using the AD controller features of samba 4 for now and have a samba 3.x DC, that has joined the samba 4 controlled Active Directory domain, handle the file and print sharing. How much of an issue would the missing samba4

Hello all, I am facing difficulty in deciding how to go about analysis of a situation explained as follows: I have two variables Y (response) and X (explanatory) (There are several other potential candidate explanatory variables, but right now I am looking at only one variable.) Y is binary taking values 1 and 0. X is a continuous variable. Both variables are observed over a equally spaced
