applying random functions to multisets
Hi,
I am solving following problem:
Suppose I have some multiset:
> multiset <- c("a","a","c","d","d")
and rules, which operate with it (for simplicity not writen in R functions)
> rule1: "a" -> c("a","b")
> rule2: "a" -> c("a","c")

Multiset Permutations
Dear R users,
I want to perform an exact permutation of multisets. I have looked at the
coin package, but it doesn't seem to offer what I am looking for. I want to
perform permutations (exact - without duplications) on multisets of scalars
(e.g., the multiset 0,0,1,2,2). I want to output all the possible
permutations into a data frame so that each multiset p...

generate combination multiset (set with repetition)
Hi,
This has been asked before but not sufficiently answered from what I
could find. How do you create combinations
with repetitions (multisets) in R?
If I have
> set <- array(1:3)
And I want to choose all combinations of picking 2 numbers, I want to
get a print out like
[,1] [,2]
[1,] 1 1
[2,] 1 2
[3,] 1 3
[4,] 2 2
[5,] 2 3
[6,] 3 3
subsets(set, 2, allow.repeat=T) should work, but I can&...

[LLVMdev] RFC: Indirect Call Promotion LLVM Pass
...nts become available in llvm IR.
b. Current implementation only transforms the first hot target, the rest
of the targets are never considered even if they are relatively hot.
We are evaluating a new solution which depends on the
presence/availability of functions counts in clang. We form a sorted
multiset of all functions counts. A given indirect target is considered
for inlining if the targets count at the call site falls within one of
the ranges that form the top 0-10%, 10-20% or 20-30% of the sorted
multiset. Weve added checks which become stricter as the target count
falls farther away from t...

New package: sets
Dear useRs,
The new 'sets' package made it to CRAN, supporting:
o data structures for sets, fuzzy sets, multisets, and fuzzy multisets
o the use of (most) R objects as elements
o standard set operations (union, intersection, complement, Cartesian
product, power set, ...)
o support for several fuzzy logic systems
An introductory vignette is also available.
David and Kurt.

R, VR, and Debian
...stallation, and installed R on it,
along with several packages -- including e1071 and
the "Bundle" VR -- by means of the Debian package
manager. Most of the time, R works fine. But not always.
Just now, I wanted to try the code suggested by
Johannes H?sing for "Stroparia"'s Multiset Permutation
question.
The first line is "library(e1071)" -- this failed
because:

[LLVMdev] SUBALLOCATOR
...//dl.dropbox.com/u/8437476/works/countertree/index.html ). I am
writting you because I think a part of this library, the suballocator, can
be useful to you.
The suballocator works with the allocator for to improve the allocation
speed of fixed size elements, like in the Standard Library list, set,
multiset, map and multimap.
In the benchmark done with CLANG 3.0 (

Need help imputing missing data using mice and outputting them
...I've been doing:
imputationmodel<-mice( MyData[ c (grep("Q20_", names(MyData)) ) ] )
multipledataset<-complete(imputationmodel,action="long")
write.table(as.data.frame(lapply(multipledataset,function(x) {as.numeric(is.element(x,5))} )), sep="\t",file="multiset.txt",row.names=F)
The last line (write.table) makes it so that all the values get changed into 0s and 1s. How could I output the original imputed values (in my case, they should be 1s or 2s or 3s or 4s or 5s) rather than 0s and 1s?
Thank you very much!

suggestion for "sets" tools upgrade
First, let me apologize in advance if this is the wrong place to submit
a suggestion for a change to functions in the base-R package. It never
really occurred to me that I'd have an idea worthy of such a change.
My idea is to provide an upgrade to all the "sets" tools (intersect,
union, setdiff, setequal) that allows the user to apply them in a
strictly algebraic style.

a complex availability problem
Ok, this is a hard one and I just thought I''d see if people on the
list had any suggestions on how they would approach this, I''ve not
started to implement the rails to handle this yet as I''m still at the
paper planning phase.
I''m building an app that has to handle availability for travel packages.
The complexity comes in that a person can choose a start

Generating unique permutations of a vector
Hi all,
I try to generate sets of strategies that contain probability
distributions for a defined number of elements, e.g. imagine an
animal that can produce 5 different types of offspring and I want to
figure out which percentage of each type it should produce in order to
maximize its fitness. In order to do so, I need to calculate the fitness
for all potential strategies. As an example, if I
