How consistent is predict() syntax?
I have a situation where lagged values of a time-series are used to
predict future values. I have packed together the time-series and the
lagged values into a data frame:

Problem Updating from 2.71 to 2.8 in Ubuntu
Hello,
I have recently installed Ubuntu (8.10) Intrepid Ibex and I am trying to get
R version 2.8. I have changed my /etc/apt/sources.list file to include a
mirror. I have also added the Vincent Goulet key. However, whenever I run
sudo apt-get update
sudo apt-get install r-base
it installs version 2.71. Given that I am new to Ubuntu, is there
anything that I need to do to make ubuntu get

calculate differences - strange outcome
Dear List,
I ran into some trouble by calculating differences. For me it is
important that differences are either 0 or not.
So I don't understand the outcome of this calculation

but I would like to know the reason.
Maybe someone can help me?

nls & optimize
Hi all,
I'm plotting to get the intersection value of three curves. Defining
the x-axis as dsm, the following code works;
dsm = c(800,600,NA,525,NA,450,400,NA,NA,NA,0)
s3 = seq(0.05,1.05,0.1)
plot(dsm,s3,col="blue",las=1,ylab="fraction",xlab="distance (km)")
fc <- function(x,a,b){a*exp(-b*x)}
fm <- nls(s3~fc(dsm,a,b),start=c(a=1,b=0))
co <- coef(fm)

LLVM v3.9.0 and math built-ins
A little while ago I asked a question on CFE-Dev about a change in the
behaviour of programs using the ISO C math functions, although that question
should have been put to LLVM-Dev. But I got excellent clarification of the
problem anyway. However, since then I have been trying to adapt our
out-of-tree implementation to get the previous behaviour. The problem is
that something like:

performance issue with merge
Hi,
I'm trying to merge a couple of matrices together. The matrices are created
from a couple of input files that have very similar (but not in all cases)
values in first and second column. 1st and 2nd column are used to generate
rownames, the actually interesting value is in column 3. I'd like to merge
the different files by the rownames generated from 1st and 2nd column. Files

R2WinBUGS problem
Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped
this multivariate normal model, which gives very plausible results in
WinBUGS even without any
initial values specified. However, when I then try to run the same model
via the bugs function in R2WinBUGS with inits specified as inits=NULL
the program stops in a dead end. So I have tried to make inits for the

LLVM v3.9.0 and math built-ins
Hi Mehdi,
The ISO C specification does permit the math functions to modify ‘errno’, but I thought that the ‘-fno-math-errno’ option was to tell the optimiser to assume that ‘errno’ is not modified by the math functions. Explicitly providing ‘-fno-math-errno’ is not restoring the elision optimisation that was performed by LLVM v3.8, and this is really only a driver option, with ‘-fmath-errno’

R-beta: spline problems(?)
Hi,
I am a total beginner with this whole thing so please have patience!
I am trying to run an S-plus program with a certain line:

This crashes with:

Apparently, this is caused by the last command of spline:

SE of ANOVA (aov) with repeated measures and a bewtween-subject factor
Hallo!
I have data of the following design:
NSubj were measured at Baseline (visit 1) and at 3
following time points (visit 2, visit 3, visit 4).
There is or is not a treatment.
Most interesting is the question if there is a
difference in treatment between the results of visit 4
and baseline. (The other time points are also of
interest.) The level of significance is alpha=0.0179
(because of an
