Help in splitting ists into sub-lists
Dear List,
Let's say I have a list whose components are 2 matrices (as exemplified in
the "mylist" object below). I'd like to create a list with components being
4 matrices based on an logical index vector. is there a way to simplify what
I'm doing to obtain the results in "mylist2"? I'd like something that would
work on an arbitrary number of elements in

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)

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,

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

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.

multiple R sessions from one working directory using GNU screen
Dear all,
I am using GNU screen to run multiple R sessions from one working
directory in order to split task, however I noticed that dataset is not
synchronized e.g. if I have two sessions R1 and R2, and I remove an
object from R1, R2 doesn't change as expected or change at random.
I have tried to save.image(), q() and then restart both sessions, but it
does not help.
Any suggestions?

Merging nested lists

I have multiple "list of lists" in the form of

I would like to merge these lists by each Name_i using rbind, but I couldn't figure out how to do it. What I want at the end is a single "list of lists", again in the form of

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.

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");

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

After manipulate my data I have ended up with 5 different data frames
with different number of observations but the same

I have two simple questions here, and hope someone can help me on this. Thanks in advance.

RJS in Internet Explorer to update a list box
Hi,
I''m trying some RJS to update a series of list boxes in which the user
selects a state, and the following list gets updated with a list of
counties, and the same for the next list of areas.
My code works perfectly (albeit a bit slow) on Firefox, but on Internet

Batch files in R
When I submit more than one batch file (same programs, different parameter
values, huge simulations, different result names) the only results that get
saved are from the *last* batch file to finish. They are all being run in
the same subdirectory (so same .RData file?)
I've done:

and I've also put
