alloca combining, not (yet) possible ?
...? Should I
adorn something with some attributes ? As far as I can tell no, but I am
no llvm expert...
For what I want to do, i will probably have a few dozen combinable
allocas in my produced code each function. So it would be worthwhile to
reduce stack space needs.
Ciao
Nat!

Wildcard for indexing?
...t with logical operators:
"Select all elements of a vector that start with A (A*) OR that start with B (B*)"
Probably that is quite easy. I looked into grep() which I think might perform such tasks, but probably there is a more straigth forward solution.
a <- c("A_A","A_B","C_A","BB","A_Asd")
a[a=="A_A"| a=="A_B"] # here I'd like an index but with wildcard

Why is as.function() slower than eval(call("function"())?
...3400 3.906 4.1055 23.153 100 b
At first I thought the gap was due to the overhead of calling c(a, list(b)). But this turns out not to be the case:
make_fn_weird <- function(a, b) as.function(c(a, b), env = parent.frame())
b_wrapped <- list(b)
make_fn_weirder <- function(a_b) as.function(a_b, env = parent.frame())
a_b <- c(a, b_wrapped)
microbenchmark(make_fn_1(a, b), make_fn_2(a, b),
make_fn_weird(a, b_wrapped), make_fn_weirder(a_b))

listing the files in a directory using regular expressions
Hi Experts,
This might be silly question that I am asking, but no way as I am new to
R.
I want to list the files in a directory using regular expression like
A_B*_C*.csv etc.
How to make this possible in R ?
I tried like this list.files(dir=".", pattern="A_B*_C*.csv") but this gives
no output, whereas list.files(.... pattern="*.csv") giving all the .csv
files in the output, which I do not want.
Thanks

Association data clobbering (foreign keys too?)
...elongs_to :b
end
so my Model A has a habtm collection of Bs *plus* a direct belongs_to
link to one B (and vice versa).
So
a = A.find(:first)
b = a.bs.first
a2 = b.a
might not give me back a, because b''s direct belongs_to a reference is
clobbered with the reference from the join table a_b (because the
foreign keys have the same name)?
Or does this only apply to non foreign key attributes?
There are no such problems if I''d make a_b a join model and have no
habtm, but a has_many :through instead?
What other options to circumvent this problem do I have (besides

How to avoid converting "_" to "." ?
It is minor thing, but how can I avoid converting "_" to "." ?
e.g. I have a data set "test.csv"
A,A_B,A_C,C,D
X,11,0,13,14
Y,21,0,23,24
and when I read it all underscores are converted to dots (:<)
> d <- read.csv("test.csv")
> d

1 X 11 0 13 14
2 Y 21 0 23 24

xtable and column headings
...order to get features like subscripts in the
column headings. I recently had to reinstall xtable and discovered that all
my LaTeX column headings were printing out in LaTeX code rather than with
LaTeX formatting. For example, with the older xtable I could give my column
a name something like "$A_b$" to get printed column heading of "A" with the
subscript "b." Now my printed column heading is "$A_b$" and the LaTeX code
in the .tex file generated by Sweave is "\$A\_b\$". It seems that the
newest version of print.xtable takes all my LaTeX special cha...

Help with Vectors and conditional functions

AA,B,C,D.. Are time series. Then there is a vector called coint_tests of length 15 which yields "yes" or "no".
I need to add a function to plot the time series Ai_Bi if the coint_tests vectors gives me a "YES".

This is a pretty basic, easy, and practical application for RoR. If you
guys know of any resources on the net to answer these questions let me

Question 1:
Basically, I have a many-to-many relationship that I want to add records
to. I use something like this to add records in the A_B table:
c.clubs<<Club.find_all_by_name(params[:clubs])
This takes the ones that already exist and establishes a relationship
between A and B.
What if I want to take ones that don''t exist in params[:clubs] and have
those added to Club table? Is there any shortcut operator for doin...

problems with strsplit using a split of ' \\\ ' : a regex problem
...bol).
So I wrote a simple little function to do this:
get.first.id.func <- function(vec, splitter){
vec.lst <- strsplit(vec, splitter)
first.func <- function(vec1){vec1[1]}
vec.out <- sapply(vec.lst, first.func)
vec.out
}
For a trivial example, this works:
> a <- c("a_b", "c_d")
> get.first.id.func(a, "_")
[1] "a" "c"
I am running into problems, however, with the real world split of ' \\\ '
I'm not even able to construct a sample vector of my own! Here is what I
get:
