Sum vectors and numbers
We want to sum many vectors and numbers together as a vector if there is
at least one vector in the arguments.
For example, 1 + c(2,3) = c(3,4).
Since we are not sure arguments to sum, we are using sum function:
sum(v1,v2,...,n1,n2,..).
The problem is that sum returns the sum of all the values present in its
arguments:
sum(1,c(2,3))=6
sum(1,2,3)=6
We do not want to turn sum(v1,v2,...,n1,n2,..) to

Matrix Size
hi -
i just started using R as i am trying to figure out how perform a linear
regression on a huge matrix.
i am sure this topic has passed through the email list before but could
not find anything in the archives.
i have a matrix that is 2,000,000 x 170,000 the values right now are
arbitray.
i try to allocate this on a x86_64 machine with 16G of ram and i get the
following:

r: functions
hi all
i have a function that uses two inputs, say xdata and ydata. An example
is the following,
simple1<-function(xdata,ydata)
{
ofit<-lm(ydata~xdata)
list(ofit)
}
say i use arbitray number for xdata and ydata such that
D =
x1 x2 y
1 1 10
2 6 6
3 10 7
x<-D[,1:2]
and
y<-D[,3]
if one uses these inputs and rund the program we get the following:
>simple(xdata=x,ydata=y)

Feed list of vectors to vioplot()?
Hi,
I have a list of vectors and am trying to coerce them into something that
vioplot will take as groups of data to be plotted independently. Can
someone nudge me into the right direction?
Thanks, Joh

Extracting a range of elements from a vector
Dear R users
I am R newbie creating a function that implements the poker test to test
pseudo random bit generators.
Iam reading the bits from a text file (1 bit per line), which causes
each bit to be stored in an element of a numeric vector.
What Iam trying to do is to extract a "block" of bits of arbitray size
from the original vector into a smaller numeric vector and then count

rsync for realtime filesystem replication.
Apologies in advance for a kind of long question:
I've written an application called changedfiles
(http://www.bangstate.com/software.html#changedfiles), which consists of two
parts: a linux kernel module that reports all file operations to a device
special, and a userspace daemon which can take arbitray shell action on files
matching regexp rules specified in a config file.

R support for 64 bit integers
Are integers strictly a signed 32 bit number on R even if I am running a 64
bit version of R on a x86_64 bit machine?
I ask because I have integers stored in a hdf5 file where some of the data
is 64 bit integers. When I read that into R using the hdf5 library it seems
any integer greater than 2**31 returns NA.
Any solutions?
Thanks,
Theo

Starting estimates for nls Exponential Fit
Hello everyone,
I have come across a bit of an odd problem: I am currently analysing data
PCR reaction data of which part is behaving exponential. I would like to fit
the exponential part to the following:
y0 + alpha * E^t
In which Y0 is the groundphase, alpha a fluorescence factor, E the
efficiency of the reaction & t is time (in cycles)
I can get this to work for most of my reactions,

Remove data 3 standard deviatons from the mean using R?
Hi Everyone,
I have a very long list of data-points (+2300) and i know from my histogram
that there are outliers which are affecting my mean.
I was wondering if anyone on here knows a way i can quickly get R to
calculate and remove data which is 3 standard deviations from the mean? I am
hoping this will tidy my data and give me a repeatable method of tidying for
future data collection.

LispStat, R and ViSta [was: Re: Status?]

when to use "I", "as is" caret
Dear community,
I've check it while working, but just to reassure myself. Let's say we have
2 models:
model1 <- lm(vdep ~ log(v1) + v2 + v3 + I(v4^2) , data = mydata)
model2 <- lm(vdep ~ log(v1) + v2 + v3 + v4^2, data = mydata)
So in model1 you really square v4; and in model2, v4*^2 *doesn't do
anything, does it? Model2 could be rewritten:
model2b <- lm(vdep ~

About statistical independece or cumulant books or papers
Hey
I am now studying the statistical indepdence between
arbitray two random variables.
And want to use Cumulant or related method as
the starting point.
So anybody has some hints on providing me some
good textbooks or papers on cumulant or statistical
indepdence criteria?
Thanks a lot.

Svy function doesn't work nested in user-defined function
Hi R-help,
I posted about this late yesterday but got no response. I may have put
TMI in the original request. Not to mention I couldn't cut and paste
yesterday because I was working R off a non-network computer while
asking for help on a network computer.
Essentially, I have this user-defined function:

Failing to understand getrusage()
I'm failing to understand how getrusage() works, which is a bit perplexing,
because it doesn't seem like it would be terribly complicated.
I've attached the code. My aim is to verify that I can use getrusage() to
do (admittedly crude) instrumentation of which functions in my program are
allocating lots of memory[1]. So I figure I can call getrusage() at various
points and look at
