Saving iterative components
Hi, I need help!
I am trying to iterate an iterative process to do cross vadation and store
the results each time.
I have a Spatial data.frame, called Tmese
> str(Tmese)
Formal class 'SpatialPointsDataFrame' [package "sp"] with 5 slots
..@ data :'data.frame': 14 obs. of 17 variables:
.. ..$ ID : int [1:14] 73 68 49 62 51 79 69 77 57 53 ...
.. ..$

continue for loop in case of erros
Dear all,
I have a for loop which includes nls model estimation.
The loop breaks after the first non-convergence error.
How can I make the loop continue and try to estimate all models?
I suppose it should be sth like: if(...) { next }
but I have no idea how to setup the arguements...
Thank you!

applying a function over an array
Is there a way to apply a function with several arguements over an
array? For instance if you had a function d<-function(a,b,c) {a+b+c} and
a 4,3 array, could you apply the function over each line of the array?
tapply seems to only allow one argument, and I just can't think of a way
to explicitly tell R that I am passing it 3 distinct objects instead of
1 complex one. Thank you as

question about deparse(substitute(...))
Dear R helpers:
I like to apply deparse(substitute()) on multiple arguments to collect the
names of the arguments into a character vector.
I used function test.fun as below. it works when there is only one input
argument. but it does not work for multiple arguements. can someone kindly
help?
test.fun <- function(...){deparse(substitute(...))}
test.fun(x) #this works
test.fun(x,y,z) # I like

DRBD question.
I'm going to have to be a little vague on this one, but hope I provide
enough to make the question clear. I'm not doing the work on this
server, a co-worker is, but I said I would ask for him.
He is trying to get DRBD installed. He's using Centos 5.1 and the yum
repos, but is getting problems with things like the kernel, drbd.so, and
the likes. All install fine, but I'm not

R-beta: Polynomials in lm/glm
R users,
I was a bit surprised to find that when I attempted to add a polynomial
term to a linear model using either lm or glm as could be done in S
resulted in a fit without that term included and without warning(!!), e.g.
> lm(response ~ x + x^2, data).
As far as I can gather, there is no poly() yet in R, and if lm/glm do not
allow functions of variables as their formula arguements, is

Forward Stepwise regression with stepAIC and step
Dear all,
I cannot seem to get the R functions step or stepAIC to perform forward
or stepwise regression as I expect. I have enclosed the example data in
a dataframe at the end of this mail. Note rubbish is and rnorm(17) variable
which I have deliberately added to the data to test the stepwise procedure.
I have used
wateruse.lm<-lm(waterusage~.,data=wateruse) # Fit full model

Help using tapply with multiple variables
Dear list,
I have the function (as a simple example, which is actually part of a
larger function)
pres.test<-function(N0=N0, N1=N1)
{
dt<-5
r<-log(N1/N0)/dt
r
}
which calculates the annual growth rates in a population
Where N0 is the population classified into age intervals, say 5
years, at time=1995, and N1 is the population by 5 year age classes
at time=2000.

diax request
First of all great job on diax. I downloaded it and tried it, could not
connect, got an authentication rejected,but I have not had a chance to
figure out why yet - tried with a working gnophone setup in the
configuration files.
Is there any way to pass command line arguements to the program ? Where I
see a real niche for a lightweight softphone is being able to serve the

"vcov" error in svyby and svytable functions
Hi,
I'm trying to compute survey svytable statistic on subsets by using the
svyby function.
Here is the code:
b<-svyby(~V024+V751, by=~V025, design=strat2, svytable, round=TRUE)
The vars, V024, V751 and V025 are factors. The by var has 2 levels, and
hence there will be two subsets. strat2 is created by the svydesign function.
It's giving me the following error:

question on assigning an argument in a function that is create by the function itself
Hi,
I need some help with making a function a bit more elegant. How would you
all suggest avoiding the problem I've made myself below - I've written a
function that creates a temporary matrix by subseting a larger one I assign
it. I then call vectors from that matrix, add each item in the vector to
create a cumulative vector for each factor, and then patch them all back
together.

T1 or T1PRI? which sould i use?
Hi
i'm using asterisk in a pre-paid calling card like system
and have a few questions.
1) Should i use Voice T1's or PRI. Please give arguements
for and against.
2) is there any already configured * scripts for making
calling card calls? are they GPL or Commercial?
3) if they are GPL where can i get my hands on them.
4) is there any work on intergrating openDSP libraries into

Centos 4.0 and Named
I am failing to get Named started.
I copied my named.custom and zone files to a diskette from my 3.3 build.
I installed 4.0 from scratch and did the updates.
I edited /etc/named.conf (which I realize is a link) to include named.custom
I cp named.custom into /etc (all of this was done while logged in as root)
When I try to start named from the services GUI (using GNOME) and I get

iterative variable names
Hi,
I'm trying to assign iterative names to variable, but all my attempts have
failed. I have a loop, and for every iteration, I need to create a variable,
and I'd like to name them iteratively, such as:
for(i in 1:10)
{
x_i <- c(values)
}
I need it to return ten variables: x_1, x_2, ..., x_10
How can I do it?
Thank you very much!

Simplify formula for iterative programming
Dear R-ians,
I am looking for the simplification of a formula to improve the
calculation speed of my program. Therefore I want to simplify the
following formula:
H = Si (Sj ( sqrt [ (Ai - Aj)?? + (Bi - Bj)?? ] ) )
where:
A, B = two vectors (with numerical data) of length n
sqrt = square root
Si = summation over i (= 0 to n)
Sj = summation over j (= 0 to n)
Ai = element of A with index i

how to run .r batch file
I am completely new to R, but have some bg in cs and stat.
since R has an interactive programming environment, I thought I could write my command in a file and run it in batch mode in the Rgui. but it didnt work. I checked the doc. it said Rcmd BATCH inputfile. it didnt work either.
Can someone help? thank you. thank you.
also if you can shed some light on passing command line arguements (like

iterative output to file by row
Hi,
I'm sort of a newbie to using R to deal with array data. I'm trying to
create a simple filtering function, which outputs only the rows of a
data frame that satisfies a specific criterion. I've set up an
iterative loop to apply the condition to each row. I can create a new
matrix and use rbind to fill it in row by row in the loop, before
writing the whole matrix to file. But

Migrate BACK to WINDOWS -> Talk me out of it QUICK
Not thinking about migrating back due to issues, it is more due to
implementation needs and a little situation I have been wrestling with
with for a bit now, and would love some feedback
First a little history:
We currently have 10 locations connected via a dedicated 1/2 T-1.
Last year I migrated from a WINNT domain to a Samba/LDAP domain. It
has been running great. Basically did this for
