Expressions returned by a Package function
Hello,
I have a function 'ewrap' (see below for definition).
It takes 3 expressions and returns another expression e.g.
map <- ewrap({
len <- length(r$addon)
rhcollect(len,1)
})
becomes:
expression({
NULL
result <- mapply(function(.index, k, r) {
{
len <- length(r$addon)
rhcollect(len, 1)
}
},

handle large matrix in R
Dear all,
I've run into a question of handling large matrices in R. I'd like to
define a 70000*70000 matrix in R on Platform:
x86_64-apple-darwin9.8.0/x86_64 (64-bit), but it seems to run out of memory
to handle this. Is it due to R memory limiting size or RAM of my laptop? If
I use a cluster with larger RAM, will that be able to handle this large
matrix in R? Thanks much!
Best,
Hui

scaling of parameter errors in a weighted regression using nls
I noticed that nls treats weights as relative and that the absolute size of the weights w in
the following script has therefore no influence on the errors of the parameters reported in the summary
a<-1
b<-3
x<--100:100
y<-a*x+b
yeps<-y+rnorm(length(x),sd=1)
w<-rep(1,length(x))
plot(x,yeps)
lines(x,y)
fit<-nls(yeps~p1*x+p2,start=list(p1=a*1.5,p2=b*1.5),weights=w)

How to subset a matrix?
Hi all,
Lets say I have a matrix A which is m x n.
I also have a mask matrix MASK which is m x n with values in T/F, where T
values make a sub-matrix in regutangular shape...
I applied B=A[MASK] and it didn't work as expected...
Any thoughts?

Quadrat counting with spatstat
I have photographs of plots that look like so:
http://r.789695.n4.nabble.com/file/n4631960/Untitled.jpg
I need to divide it up so each circle has an equal area surrounding it. So
into 20 equal segments, each of which contains a circle. Quadratcount is not
sufficient because if I divide it up into 36 equal quadrats, some quadrats
do not contain one of the circles.
I'm not even sure how to

In STATA, the "y" appended to " var_" is called the local variable and

Remove reciprocal data from a grouped animal social contact dataset
Hi r-help forum,
I have been collecting contact data (with proximity logger collars)
between a few different species of animal. All animals wear the
collars, and any contact between the animals should be detected and
recorded by both collars. However, this isn't always the case and more
contacts may be recorded on one collar of the two. This is fine, it
depends on battery life and other

Questions and a blockpull issue
Coming off of xen environment; still testing with kvm, just a few
questions:
1. What is the roadmap for release of qemu-kvm 1.1 and libvirt 0.10.2 for
el6, cause I had to compile from upstream to get the latest stuff.
2. Should not virt-manager show the sparsed disk size instead of actual
reserved size of a vm?
3. Where is the virsh bash_completion conf.d file from upstream; since el6

Creating "%d/%m/%Y %H:%M:%S" format from separate date and time columns
Hi R forum,
Each row of my data (below) show a new contact event between animals.
In order to ultimately look at the patterns of intervals between
contacts, I need to calculate a contact end time. The contact starts
at the date and time shown in V4 and V5, and lasts for the duration
shown IN SECONDS in V6:

R and Hadoop Integrated Processing Environment - RHIPE
Hello,
We have created an interface between R and Hadoop so that the user
can, after a fashion, interact with very large datasets
using the Map Reduce programming model. We also use IBM's TSpaces to
implement a shared memory implementation that can be
accessed via R(somewhat like networkspaces). RHIPE uses Rserve to
execute R code.
Some of the functions implemented are:

lib.fixup, .GlobalEnv, and R1.5.0 (PR#1556)
Full_Name: Mark Bravington
Version: 1.5.0
OS: Windows 2000
Submission from: (NULL) (140.79.2.3)
In R1.3.1, I used the following code inside a function to set a "path" attribute
to .GlobalEnv:
env_ pos.to.env( 1)
attr( env, 'path')_ .Path # .Path is a named char vector of length 1
.Internal( lib.fixup( env, .GlobalEnv)) # adds the attribute
And this works fine. But in
