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,

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

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?

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

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

write dataframes
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,
data.frame': 47 obs. of 3 variables:
$ ORF : Factor w/ 245 levels "YAL038W","YAL054C",..: 10 19 38 39 44

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

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:

samba-tool ldapcmp without --filter errors out.
Hai,

I've just upgrade samba on my DC's from 4.10.10 to 4.11.2.
Which went fine offcourse ;-) but when i checking my replications i noticed the following.

I want to calculate the bias and variance of an estimator for several values
of two parameters a and b.
For example :

Can one do array of arrays ? I have tried and it did not work.
Actually I would like to get this array for several values of the number of

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
Explorer it clears the list box (instead of filling it) and Netscape
shows all the counties cramped together on one

[LLVMdev] Another missed optimization opportunity?

I was thinking along those lines, but I haven't been able to come up
with a specific instance of what could possibly be aliased.

[LLVMdev] Another missed optimization opportunity?
I was suprised to find that some bitcode I'm generating isn't getting
optimized. Here, I'm doing the equivalent of "myarray[5]++" (on an
"extern int *myarray"), repeated three times:
