Hi, I was reading the book on "Mixed Effects Models and Extensions in Ecology with R" by Zuur et al. In Section 6.2, an example is discussed where a gamm-model is fitted, with a smoother for time, which differs for each value of ID (4 different bird species). In earlier versions of R, the following code was used BM2<-gamm(Birds~Rain+ID+

...ce, and I'd also like to give the data owners suggestions on how to reformat their data so that it is easier to consume by machines, while being easy to read for humans. The early records are a serious machine parsing challenge as they are tiff images of old notebooks ;-) tia Tim Tim Coote tim at coote.org vincit veritas

Hullo I may have missed something blindingly obvious here. I'm using xts to handle some timeseries data. I've got daily measurements for 100 years. If I try to reduce the error rate by taking means of each month, I'm getting what at first sight appears to be conflicting information. Here's a small subset to show the problem: A small set of data: > vv x

I have experienced a couple of power failures since installing CentOS 5, both while I was working on the system. The first time, several weeks ago, I thought there was some "feature" that I had never seen before but couldn't really put my finger on it. The power came back on after a few seconds and I never missed a beat. I also shrewdly forgot about the anomaly that I had

Hi, I'm moving (slowly) to R from STATA. I often have need to move through a set of tasks across a series of years. In this case, you can see that I'm mimicking -reshape- in STATA, but I'm less interested in the task than in programming R. library(foreign) mydata<-read.dta("z:\example.dta") for (y in 2000:2002) {

Hi Peter, I tried isolinux-1.73, its great! Because of some problems making a universal boot-CD I tried to use bocs-1.4 (a PC emulator, very good). This emulator is able to boot a win98-installation-CD but fails on self made isolinux-1.73-CDs. I can coot the isolinux-CD by a real PC without problems. Also a SuSE-Linux CD or an image of it which claims to use solinux-1.62 is bootable in bochs, but

I've hunted around to try to work this out and cannot find anything aposite, although there are exhortations to read News files and the fine manual in response to similar queries. Hope I haven't missed anything obvious. I want to read in csv files that contain dates, or date times. If I read them in directly: x <- read.csv ("file") the relevant dataframe column is of type
