Matrix indexing in a loop
How do you specify matrix location a[i,j] (or a[i-1,j], etc.) in a "for"
loop?
I am looking for a flexible method of indexing neighbors over a series
of lags (1,2,3...) and I may wish to extend this method to 3D arrays.
Example:
Data matrix
> fun
[,1] [,2] [,3]
[1,] 1 5 9
[2,] 2 6 10
[3,] 3 7 11
[4,] 4 8 12
For each element a[i,j] in

[LLVMdev] Load from abs address generated bad code on LLVM 2.4
This is x86_64. I have a problem where an absolute memory load
define i32 @foo() {
entry:
%0 = load i32* inttoptr (i64 12704196 to i32*) ; <i32> [#uses=1]

generates incorrect code on LLVM 2.4:
0x7ffff6d54010: mov 0xc1d9c4(%rip),%eax # 0x7ffff79719da

I have 2700 text files in a folder and need to apply
the same program/procedure to each individually. I'm
trying to find how to code something like:
For each file in <Folder> do {<Procedure>}
is there an easy way to do this? other suggestions?
I have tried to list all the files names in a vector
e.g.

To all TextMate users that wants to run tests with cmd + r in Rails 2.1 and above.
Because the require ''test_helper'' at the top of all the tests is
relative now (it used to be something like require ''../test_helper''),
you can''t just run the file with ruby anymore. And running the file
with ruby is exactly what command + r does. Which means you can''t
easily run your tests from textmate.

compiling tests/Embedding
I am compiling the Embedding examples in the tests directory and get an
undefined reference. I include the make output as well as grep'd output
of nm on libR.so and compiler and arch information. Do I have an
improperly built R shared library or is there a problem with the
Embedding tests or something else I am not seeing?
Thanks for any help!

aggregating data with Zoo
Is there a way of aggregating 'zoo' daily data according to day of week? eg
all Thursdays
I came across the 'nextfri' function in the documentation but am unsure how
to change this so any day of week can be aggregated.
I have used POSIX to arrange the data (not as 'zoo' series) according to day
of week, but am curious if I've missed if a similar option available
