Problems with memory
Dear all,
I've started working with R (vs 1041) a few weeks ago, and now I'm
having problems with the amount of memory.
I'm working on the windows-me, my computer has 128 Mb of memory. I'm
using the R under the emacs (ESS-5.1.20) and it is started by the
command:
Rterm --min-vsize=10M --max-vsize=100M --min-nsize=500k --max-nsize=1M

Looping through R objects with $ operator and tags
Hi all,
Suppose I want to set the values in a column to the log of the values
of another column like so:
object$LogDist <- log10(object$Distance)
How do I loop through the objects if I have object1, object2, etc to
perform this function?
object1$LogDist <- log10(object1$Distance)
object2$LogDist <- log10(object2$Distance)
object3$LogDist <- log10(object3$Distance)

Create R object
Dear R users,
I have two simple questions here, and hope someone can help me on this. Thanks in advance.
1.
I have a list object lst=list(a1=matrix(rnorm(4),2,2), a2=matrix(rnorm(4),2,2),a3=matrix(rnorm(4),2,2)). Here I only use three elements for illustration, and in fact the length of lst, n, is unknown in advance. I want to define an object for each element of this lst, and the objects have

remove multiple objects starting with same name
Hi,
I'm trying to figure out syntax R function rm() needs to remove all objects
starting with same name. For example, if I have object1, object2, object3,
i want to do an operation similar to UNIX rm object*
Thanks.

Transactions with multiple databases
hi,
i have problem with transactions and multiple databases.
Object1 and Object2 are two different models/databases with different

one model:

object1.value1 = "123456"
object1.save
do_some_error
end
it''s ok, error is produced, nothing is commited and database is unchanged.

Struggling to compute marginal effects !
In that case, I can't work out why the first model fails but not the
second. I would start looking at "Data" to see what it contains. if:
object2 <- polr(Inc ~ Training ,Data,Hess = T,method = "logistic" )
works, the problem may be with the "Adopt" variable.

Rcmdr plugins produce error
I recently updated all my plugins, and for the fun of it, I added ALL the Rcmdr Plugins to my collection to see what functionality might exist. I started Rcmdr and loaded ALL the available Plugins from to the Rcdmdr Tools menu.
To my suprise Rcmdr produced a number of warnings and finally an error. The error suggests that some of the extensions are incompatable with each other because of menu

program never enters browser mode when I add browser()
Dear All
I have a program that breaks at the following lines of code:
bigfunction =
{
...
object1 = myfunction(x)
object2 = strsplit(object1, ",")[[1]]
...
}
where myfunction is defined elsewhere outside of bigfunction.
The error I get is "error in strsplit() -- object1 not found".
However, when I insert browser() into my code so that the above reads,

Hi,
After manipulate my data I have ended up with 5 different data frames
with different number of observations but the same
number of variables (columns)
An example, if I write str(object1), I see this,

returning argument names
Dear r-list folks,
I have a problem which has been bugging me for a while now and I was hoping
someone out there might be able to help.
If I have a user-defined function with an indeterminate number of
arguments, using the well-known "..." construct, how can I get the
function to return the names of the items which were the arguments of the
function as part of the function's

validObject does not check validity of slots
The documentation for validObject suggests that slots are checked for
validity, but validObject seems only to check that the slot has
something claiming to be correct; validObject(obj) does not perform
the equivalent of validObject(obj at y) for slot y.
This is also the second problem issue reported in

Pb with validObject(..., complete=TRUE)
Hi,
When called with complete=TRUE, validObject() is supposed to work in a
recursive manner. But here is a situation where it doesn't seem to be
the case.
Let's define a class with a validity method:
setClass("PosInts", representation(ii="integer"))
setValidity("PosInts",
function(object)
{
if (!all(object at ii > 0))

books on Time serie
A time series text with a title that seems designed to hide its
wide scope is:
Forecasting with Exponential Smoothing
The State Space Approach
Hyndman, R.J., Koehler, A.B., Ord, J.K., Snyder, R.D.
Springer 2009.
This book is actually an excellent overview of time series theory,
ARIMA as well as state space. It is of course, in part, a manual

casting a character vector as an object
Greetings,
I need to compare the ratios of vector sizes like this:
length(object1) / length(object2)
I have many vector objects to compare, so I would like to do it in a loop.
I created a loop like this:
mat1 <- matrix()
for (i in 1:6)
{
for (j in 1:6)
{
mat1[i,j] <- length( paste("object",i,sep="")) /

How to create a list that grows automatically
Dear R users
I would like to know if there is a way to create a list or an array (or
anything) which grows automatically as more elements are put into it. What I
want to find is something equivalent to an ArrayList object of Java
language. In Java, I can do the following thing:
// Java code
ArrayList myArray = new ArrayList();
myArray.add("object1");
myArray.add("object2");

How do I get an array of object ids?
If a = object, then a[:id] => 11 (ie, the primary key value of object.
But if bs = [ object1, object2], then bs.each { |b| = b[:id] } => bs
What I want is an array of the object ids?
Suggestions?
