Unreasonable syntax error

Hi all,
I just wrote a program in R by editing it in Microsoft Word and then pasting
into the text editor of R. The above is the file.
And below is what the console complains.... Why doesn't it recognise 'r'??
I have to mention that at least when I typed this first several lines into
the console, the first error didn't

Four concurrent Markov chains
Hi,
I am trying to write a simulation of the movements of four animals between
six patches. The movement between patches is based on a first-order Markov
chain so that the next patch they visit depends on the patch they were in
before.
I have written code that allows me to simulate the movement of one animal
but when I add more there seems to be a problem and all chains come back as
N/A. I can

matrix multiplication
Hi,
Try this:
#mat1 is the data
res<-do.call(cbind,lapply(seq_len(nrow(mat1)),function(i) {new1<-do.call(rbind,lapply(seq_len(nrow(mat1[-i,])),function(j) {x1<-rbind(mat1[i,],mat1[j,]); x2<-(abs(x1[1,1]-x1[2,1])*abs(x1[1,5]-x1[2,5]))+(abs(x1[1,2]-x1[2,2])*abs(x1[1,6]-x1[2,6]))+(abs(x1[1,3]-x1[2,3])*abs(x1[1,7]-x1[2,7]))+(abs(x1[1,4]-x1[2,4])*abs(x1[1,8]-x1[2,8]))}));new1}))

[LLVMdev] Is Loop Dependence Analysis Printing Correct Stats?
Hi;
I was playing with the -lda pass of LLVM on the following program-
#include <stdio.h>
void main()
{
int a[10];
int i;
for(i = 0; i < 4; i ++)
{
a[i] = a[i-1]+1;
}
}
I run the following commands -
clang a.c -emit-llvm -S
opt -analyze -stats -lda a.s
The output is -

Is there any easy/fast way to combine vectors with restrictions?
Example:

I want all combinations of this 3 vectors with length=2.
Like this:
1,4

call queue help
Guys I am having some serious issues with my call queue and Management

I have a single queue for my tech support department. I originally was

testing weekends, but it hasn't worked out since. It would only let one

dim enquiry
This is a minor question, but is there any difference between the two
objects
fred <- structure(1:10, dim = c(2,5))
and
fred <- structure(1:10, .Dim = c(2,5))
Should I be using one rather than the other? Thanks, Jonathan.

GoSub & Queue
I have a caller screen queue setup. Basically a caller calls in, goes
through a IVR, and before that caller is put into the queue, they get a sub
ran on them first asking for them to say there name. That gets saved and
they are entered into the queue using Queue(mainqueue,,,,300).
In the queues.conf i have a list of members these are

logistic regression - glm() - example in Dalgaard's book ISwR
Dear R-list members,
I would like to pose a question about the use and results
of the glm() function for logistic regression calculations.
The question is based on an example provided on p. 229
in P. Dalgaard, Introductory Statistics with R, 2nd. edition,
Springer, 2008. By means of this example, I was trying to
practice the different ways of entering data in glm().

Help with ddply to eliminate a for..loop
I created a small example to show something that I do a lot of. "scale"
data by month and return a data.frame with the output. "id" represents
repeated observations over "time" and I want to scale the "slope"
variable. The "out" variable shows the output I want. My for..loop
does the job but is probably very slow versus other methods. ddply

help on extract variance components from the fitted model by lm
Hey, all: Do we have a convenient command(s) to extract the variance
components from a fitted model by lm (actually it's a nexted model)?
e.g.: using the following codes we could get MSA,MSB(A) and MSE. How
to get the variance component estimates by command in R rather than
calculations by hand?

cumulative sum of within levels of a dataframe
This one should be easy but it's giving me a hard time mostly because tapply
puts the results in a list. I want to calculate the cumulative sum of a
variable in a dataframe, but with the accumulation only within each level of
a factor. For a very simple example, take:
> df <-
data.frame(x=c(rep(1,5),rep(2,5),rep(3,5)),fac=gl(3,5,labels=letters[1:3]))
